 The cost of changing locks can vary significantly depending on several factors. Here's a breakdown of the potential costs involved:

1. Locksmith Fees:

 Hourly Rate: Locksmiths typically charge an hourly rate for their services, which can range from $50 to $100 per hour.

 Service Fee: Some locksmiths may charge a flat service fee in addition to their hourly rate. This fee can cover the cost of travel and other expenses.

 Emergency Fees: If you need a locksmith to change your locks outside of normal business hours or in an emergency situation, you can expect to pay higher rates. Emergency fees can range from $75 to $125 per hour, and there may be an additional trip charge of $100 to $150.

2. Lock Costs:

 Type of Lock: The cost of the lock itself will depend on the type and brand. Basic doorknob locks can cost as little as $20, while high-security or smart locks can cost several hundred dollars.

 Number of Locks: The total cost will also depend on the number of locks you need to change.

3. Additional Factors:

 Door Type: The type of door you have can also affect the cost of changing locks. Some doors may require more specialized tools or techniques, which can increase the labor cost.

 Complexity of Installation: If the installation is more complex, such as if you need to change the strike plate or reinforce the door frame, the cost will be higher.

Overall, you can expect to pay anywhere from $100 to $500 or more to change your locks, depending on the factors mentioned above.

Here are some tips to help you save money on changing your locks:

 Get quotes from multiple locksmiths: Compare prices from several locksmiths in your area to find the best deal.

 Consider changing the locks yourself: If you are comfortable with basic DIY projects, you may be able to save money by changing the locks yourself. However, it is important to make sure you have the necessary tools and knowledge to do the job properly.

 Choose basic locks: If you are on a budget, you can save money by choosing basic doorknob locks instead of high-security or smart locks.

 Change locks during normal business hours: You can avoid paying emergency fees by scheduling the work during normal business hours.

Antique and Specialty Furniture Locks

How Locksmiths Open and Make Keys for Antique Furniture

Antique furniture carries a unique sense of history, character, and elegance. Whether it is an inherited mahogany desk, a vintage wardrobe, a delicate curio cabinet, or an old cedar chest, these treasured pieces often feature intricate mechanical locks. However, time takes its toll: keys get lost during moves, mechanisms rust, and vintage drawers become permanently stuck shut. Restoring functionality to these specialty items requires a unique blend of historical appreciation and technical expertise in Antique Furniture Lock Repair & Key Making.

Unlike modern doors that use standardized cylinder locks, antique furniture typically utilizes lever locks or bit-key mechanisms. Opening a locked vintage piece without a key requires immense patience and specialized tools. A skilled locksmith uses a delicate technique known as lock impressioning. By inserting a blank metal key into the locked cylinder and applying gentle pressure, they can read the subtle marks left by the internal levers, allowing them to file down the blank until a brand-new, perfectly fitting skeleton key is crafted from scratch—all without damaging the delicate historical wood, brass, or iron around it.

Maintaining antique hardware also requires specialized care. Lubricating vintage cabinet locks with the wrong substances can attract dust and gum up the internal springs. Professional locksmiths can safely disassemble, clean, and restore old cabinet locks, preserving their historical value while ensuring they open smoothly for generations to come.

Why Your Business Needs an Advanced Commercial Access Control System in St. Louis

Why Your Business Needs an Advanced Commercial Access Control System in St. Louis

Securing a business in today’s environment requires much more than a standard padlock and a set of brass keys. As companies grow, keeping track of physical access becomes increasingly complicated. Traditional keys can easily be lost, duplicated without authorization, or stolen, posing a direct threat to your corporate assets, inventory, and employee safety. Upgrading to a modern Commercial Access Control System in St. Louis is no longer just a luxury for Fortune 500 companies—it is a vital necessity for local businesses of all sizes.

Traditional master key systems offer a solid foundation, but integrating modern electronic door access control changes the game entirely. With electronic solutions, business owners can manage credentials centrally. Instead of handing out physical keys that are difficult to track, you can issue keycards, mobile smartphone credentials, or biometric fob scans. If an employee leaves the company or loses their credential, you can instantly revoke their access with a few clicks on a dashboard rather than paying for an emergency rekey of every exterior and interior door.

Furthermore, high-security commercial locks and advanced access panels give you detailed audit trails. You will know exactly who entered a sensitive room—such as a server room, human resources office, or inventory warehouse—and at what precise time. This level of oversight deters internal theft, boosts regulatory compliance, and provides invaluable data if an incident ever occurs.

When paired with master key systems like BiLock or high-end panic hardware, electronic access control creates a multi-layered security ecosystem. It bridges the gap between physical durability and remote digital convenience, allowing managers to lock down facilities remotely in the event of an emergency.

The Evolution of Commercial Master Key Systems in St. Louis

 For businesses throughout St. Louis, maintaining strict physical security while ensuring operational convenience is an ongoing challenge. Implementing a robust commercial master key system allows facility managers to streamline building access without sacrificing safety. Historically, mechanical master key hierarchies—such as those utilizing high-security cylinders like ASSA Max+ or BiLock interchangeable cores—have provided reliable credential management for office complexes, retail centers, and industrial warehouses across Creve Coeur and greater St. Louis. By establishing clear access tiers, property owners can grant custodians or temporary staff entry only to designated utility zones while executive teams retain universal access. Modern GEO-targeted security audits further ensure that businesses comply with local Missouri building codes while defending against sophisticated lock-picking and bumping threats.

Allegion, a leading provider of security solutions, offers the S123 patent-protected keying system as a reliable and effective way to manage access control.

What is the S123 Keying System?

The S123 keying system is a high-security mechanical key system designed to provide enhanced protection against unauthorized key duplication. It utilizes a unique keyway design and a patented undercut feature, making it extremely difficult for unauthorized individuals to replicate the keys. This system is ideal for applications where security is paramount, such as schools, hospitals, government facilities, and commercial buildings.

 * Unique Keyway Design: The keyway features a distinctive design that is difficult to replicate, further enhancing security. This design also helps prevent unauthorized key duplication by traditional methods.

 * Restricted Key Availability: S123 keys are only available through authorized Allegion dealers, ensuring that they are not readily accessible to the public. This helps maintain the integrity of the key system and prevents unauthorized duplication.

 * Master Keying Options: The S123 system can be integrated into a master key system, allowing for hierarchical access control. This enables different levels of access for various users, simplifying key management while maintaining security.

 * Durability and Reliability: Allegion is known for its high-quality products, and the S123 keying system is no exception. The keys and cylinders are made from durable materials, ensuring long-lasting performance and reliability.

How Does it Work?

The S123 keying system relies on a combination of physical and administrative security measures. The unique keyway design and patented undercut make it difficult to physically duplicate the keys. Additionally, the restricted key availability and controlled distribution process ensure that only authorized individuals can obtain keys.

Why Choose the S123 Keying System?

 * Enhanced Security: The patent protection and unique keyway design provide a high level of security against unauthorized key duplication.

 * Controlled Access: The restricted key availability and master keying options allow for precise control over who has access to your property.

Development Of The Large Format Interchangeable Core

The development of the large format interchangeable core (LFIC) was a significant innovation in the field of lock security and convenience. It primarily aimed to address the need for scalable, versatile, and secure keying systems, particularly in environments like universities, hospitals, government buildings, and corporate campuses, where managing access across a large number of locks and users is a challenge. Here’s a brief overview of its development:

Origins of the Interchangeable Core Concept

1. Early Locking Systems: Traditional pin tumbler locks required a full disassembly of the lock cylinder to change the keying, a labor-intensive process.

2. Development of Small Format Interchangeable Core (SFIC): SFIC was introduced as a way to allow quick rekeying without disassembling the lock hardware. Manufacturers like Best Lock Corporation pioneered this design in the early 20th century.

Evolution to Large Format Interchangeable Core

1. Demand for Larger, More Robust Systems:

• SFIC had limitations in terms of durability and the ability to handle complex keying systems.

• For institutions requiring higher security and larger master keying systems, a more robust interchangeable core was necessary.

2. Design and Functionality:

• LFIC shares the same basic principle as SFIC: a removable core that can be easily swapped using a specialized control key.

• The larger size accommodates more robust internal components, better durability, and enhanced compatibility with high-security keyways.

3. Key Industry Players:

• Companies like Schlage, Sargent, Medeco, and ASSA ABLOY contributed to the development and proliferation of LFIC designs, each with proprietary features and security enhancements.

4. Benefits of LFIC:

• Ease of Rekeying: Facilities can rekey locks in seconds by swapping cores without specialized tools.

• Scalability: Supports complex master key systems with hundreds or thousands of locks.

• Security Features: Advanced LFICs include hardened steel inserts, restrictive keyways, and patented key control systems to prevent unauthorized duplication.

Current Applications and Future Trends

• Applications: LFIC systems are widely used in commercial, institutional, and government settings.

• Advancements:

• Integration with electronic and smart locks.

• Enhanced resistance to lock-picking, bumping, and drilling.

• Modular designs that allow integration with other locking technologies.

Story Of My Life...

 

What Is Your Preferred Door Hardware Color Finish?

 What Is Your Preferred Door Hardware Finish?

What is your preferred door hardware color finish? We have been taking a long look through our invoices over the last 15 years and determined the most popular and preferred color finish selections from our vast list of clients.

The stock photo above is an image of a piece of nickel. We include it here because of the sudden rise in the market price of nickel ore, just in the last 2 days. We suspect there are obvious reasons for this sudden spike, given the political and economic upheavals our world is currently experiencing, but this story made me think about the most common request for color finishes of door hardware, knobs, deadbolts, lever entrance sets. thumbpress entrance locksets, hinges, peepholes, door sweeps, blocker plates, wrap-arounds etc, among some of the products we have sold, serviced and installed over the years.

The common finishes in the market in the USA and other countries around the world are pretty much similar even though some places choose varying preferences, which could be regional among other reasons. 

I'm sure people across the industry and around the world, decorators, interior and exterior designers, locksmiths, builders, retailers etc would enjoy understanding why some color selections are made over others and if you would like to share your preferred color finish choices in the comments below that'd be great.

According to our deep dive into our books, the preferred door hardware color finishes are topped by the Satin Nickel choice.

Antique Brass comes a distant second followed closely by polished brass, with venetian bronze and florentine bronze bringing up the rear. Black is finding more traction in recent years but is still farther down the list of preferences.

We have been representing a few manufacturers over the last 15 years, including Serrature Meroni products, Assa-Abloy Lockwood, Schlage, Kwikset, Weslock, Hooply, to name a few. 

Many contractors and retailers will offer a variety of color options to fit the unique tastes of clients. Simply ask your chosen contractor if your desired door hardware color finish is available.

Sliding Patio Door Repairs - Continuing Requests for our Experience

 

We have been operating in the lock and door hardware and door repair industry for most of the last 40 years across four continents and continue to service and repair doors and door hardware for our clients today. Sometimes we receive requests to install new hardware and lock and key systems, unique door furniture that is also of a more pleasing aesthetic nature

Today, we attended to a returning clients needs after about 5 years, where the particular sliding door we worked on, had a new issue.

Previously (5 years ago) the door was incredibly difficult for the homeowners to operate because the sliding door rollers fitted to the bottom had seized up. At that time, we removed the door and carefully cleaned the sliding door rollers of the build up of animal hair, dirt, grime and other blockages, that were contributing to the problems. We used our preferred brand of lubricant to lubricate and protect the existing sliding door rollers ensuring continued use for many years to come.

Yesterday, the customer called us after 5 years requesting additional service to the same door but not for the same issue. This time the actual handle had snapped on the inside. As luck would have it, we actually had one left of the same design handle mechanism, in the same color finish and made the appointment to attend today to complete the necessary repair.

Upon our arrival onsite, the customer explained that the handle snapped yesterday because the door was slowly becoming increasingly harder to operate and slide and the handle was becoming more loose over time.

We try to be pedantic about our repair methods and after replacing the broken handle, also decided to lubricate the track and sliding door rollers again (after 5 years). The resulting repairs allow the door to slide like butter on a hot fry-pan again.

Securing Church Sacristy - Installing New Lock

 A long time and continuing client of ours contacted us last week to install their provided cam-lock to their church sacristy and wanted it keyed to suit their existing key, that operates other locks across their facility. The church already had their maintenance person install a barrel bolt to the fixed leaf of the proposed cupboard.

The difficulty was, they currently use a Ronis brand of cam-lock system in many of their other cupboards across other parts of their facility. They decided to purchase the particular cam-lock from a big box hardware, hoping it could easily be just keyed alike to their existing key. Ronis brand hardware is not a common brand of hardware found in many general supply houses or big box hardware stores and it can be difficult to re-key any old lock to their desired key.

A professional tradesperson will understand the requirements to be able to convert another brand of lock to operate with a different brand of key and often there is no way to perform the miracle and purchasing the same brand of lock is required. 

In this case, we immediately discovered that their desired key would not enter the key-way of the new lock. Being the trained and field experienced tradesman I am, i was able to modify the core to accept their desired Ronis key and could then re-key the core to the Ronis key combination.

We are choosing to not show the method we use to modify the chosen brand of core and below we will show you the installation procedure.

The first step in any installation project is to always protect the contents of the cupboard where you are working. Now, you can obviously empty the cupboard if you want, prior to beginning your work or you can choose to cover the contents with drop/cover sheets.

By using covering material to protect the contents of the cupboard, the valuable contents are protected, ensuring continued usability and cleanliness.

Again, the choice is for the installer or the site manager to make but in this case, they chose to just get it done and let the installer choose. 

It's very important that any installer of anything, be sure to accurately measure and mark before drilling anything at all. A professional will not just measure once, but probably 2-3 times, to ensure they are being as accurate as possible. It makes no sense to just do anything by eye or just wing it, as some DIY'ers might choose. If your customer is paying for a professional service, then do it the right way please.

I choose to pre-drill my first holes with a smaller drill bit, to enable me to make sure of my accuracy. If I'm out a bit, by using a smaller drill bit, i can still relocate my first hole if needed.

I like to start with a small hole drilled from the inside in the right location before switching to the outside and drilling too. This way I make a nice clean hole, generally without cracking the edges of the nicely finished and painted door.

After drilling a small hole from each side, I then can either use a spade bit or a hole saw of the appropriate size to drill the hole required for the case of the lock assembly.

Then put the collar ring and lock case into your hole, attach the appropriate cam, in this case an off-set cam that butts against the fixed leaf (other door).

Dont forget to clean up all your mess and test to finish.

How To Re-key Old Yale Mortise Deadbolt Locks

How do you re-key old Yale mortise deadbolt locks? 

This week we completed a re-key project for a new customer that involved these 75 year old Yale double cylinder mortise deadbolts. Pictured here is the image of one cylinder installed to the outside of the back door. At the left of the image you can see where someone had deliberately drilled the connecting screw to remove the ability to unscrew the screw from outside.

To be able to remove the cylinders from these really old Yale mortise deadbolts, both inside and outside connecting screws require to come out before the cylinders can be removed for re-keying.

Getting the screws out is not difficult, but that's why we are called as opposed to a handyman or carpenter contractor.

Just about any locksmith with some experience will know the method and skill required to easily disassemble any lock that uses these type of blind screws or bolts, without destruction and enabling the ability to reuse the same screws or bolts when putting the locks back together.

 Pictured next is the image of the cylinder on my bench, already removed from the door. You can clearly see the connecting screw hole.

This image displays the reverse side of the Yale mortise deadbolt cylinder. This style of Yale Mortise deadbolt lock was designed using the original rim style of pin tumbler cylinder, originally patented in 1865 by Linus Yale Jr.

Rekeying these types of older Yale cylinders can be a trap for younger players or less experienced technicians and we will explain the method below to help you with disassembly.

My pointer here is aimed at the retainer clip that holds the tail piece and cover to the rear of the cylinder and core. It is necessary to carefully squeeze the ends of the clip together first.

The next image shows me applying pressure to the retainer clip to allow the clip to be withdrawn from the back of the core.

Here you can see the clip beginning to come out of the cover plate that holds the tail piece on. Carefully use an awl to lever the clip from the core.

This image shows the retainer clip, almost fully withdrawn from the tail piece cover assembly. If you're careful enough, you will not damage the tiny clip enabling you to reuse it for reassembly,

Next, we were also required to disassemble an equally as old entrance knobset to extract the cylinder core for re-keying. To be able to remove the core (plug) from the cylinder it is necessary to remove the rear tail piece and cap assembly and retainer circlip, before you can then remove the core (plug) from the cylinder and replace the tumblers.

Here is an image of the tail piece assembly and retainer circlip removed and the cylinder ready for re-keying.

Some technicians may choose to not disassemble the clip and tail piece, preferring to remove and replace the top cap from the bible (top pinning chamber).

We choose to not show the actual re-pinning method and combination of the re-keyed locks, to protect the customers interests.
