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 on Cabinets, Armoires, Hutches and more
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.

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).
