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.

Solar Powered Power Option For Controlling Electronic Security Products
We have seen a great number of pageviews for this particular post and thought we'd follow up that article with an opinion about the multitude of electronic wireless, battery powered products that continue to enter this (getting) crowded market segment.
In a number of other articles we have written here, we have continued to question the benefits and quality of many battery powered security products.
We believe that the battery powered security devices, specifically deadbolts, entrance sets and the like can offer only 2 primary benefits that can make them appealing.
These benefits are:
1. The ability to remotely lock or unlock the product and the ability to inquire as to the lock status (is the door locked or not)
2. The ability to set automatic locking on the product, to ensure your product locks independent of human involvement.
Understanding that many consumers today are increasingly interested in the many and varied battery powered options, aimed at simplifying their lives, unfortunately the convincing sales pitches will rarely tell you about the genre's shortcomings. Specifically, the need to be constantly replacing batteries to maintain continued operations and the other primary issue, being that as all doors and frames move with weathering, settling, ground movements etc. your beaut $200+ deadbolt or entrance set WILL become useless before long and suffer electronic operability issues.
We believe that the best security offered by deadbolts and entrance sets, is still the mechanical options that can be physically operated by hand. When a condition occurs that inhibits your ease of use, mechanically you can still play with it to get it to operate. Electronically, this is not possible.

Godrej - 19th Century Indian Manufactured Money/Cash Box/Safe - Open And Make Key
A few months ago, a customer contacted us to get their money box opened and have a key made.
We made sure to take some pics of this very old box and how we made the key.
After combing through multiple key blank provider sources and trying to find even something close, our misfortune to find an appropriate key blank made us decide to modify another key blank that was suited to another product.
This particular box, we sourced back to about 1908. It appears to be in surprisingly great condition for it's age.
You can see the key blank we decided to use to modify.
This money box used a coin slot/note slot on the reverse side
of the key operated lock. The slot has a welded on flap inside that is designed to prevent removing coins or notes from the locked box.
Some of the tools, we locksmith craftsmen choose to use when impressioning keys to locks include a selection of files.
In this case we used a 4" warding file as our primary file of choice for this project.
The impression system of key fitting is a long time treasured skill, unique to the craft/trade of locksmithery. There are many books written over the years that teach the skill to new players, but practise makes perfect. After all, "Repetition Is The Mother Of Learning", according to popular theory.
One of our most popular posts in this blog is "How To Open And Make Keys To Antique Furniture Locks" and explains the method to impression keys to old fashioned 'skeleton key' type locks without damage.
You can see in this pic, we were required to drastically modify our selected blank and hand file the key. We were required to reduce the guage of the key to enable it to enter the keyway, because we could not find a suitable blank.
The finished key works beautifully in the lock, maintains it's originality (and antique value) and can only be withdrawn from the lock when the door is closed and locked.
Not a difficult project for an experienced locksmith, but rewarding nonetheless.
There are many talented locksmiths around this country and the world who still practise the art of impressioning today.
The skill is unique to the locksmith trade and one that can save customers money and heartache when needing service to their antique lock, safe or furniture product.

History Of Locks - Sargent & Greenleaf
Sargent & Greenleaf are arguably the second most well known lock industry brand. Right behind Yale. Their history dates back to 1857, when young James Sargent, an engineer with Yale & Greenleaf, decided to branch out on his own with his invention, a magnetic dial combination lock.
Halbert Greenleaf was the partner and financier (known today as Venture Capitalist) of Linus Yale Jr. Yes, the same Linus Yale Jr credited with the invention of the modern day pin tumbler lock cylinder system, which was awarded it's patent in 1865. Their joint company was called originally Yale & Greenleaf. Halbert Greenleaf ended his partnership with Linus Yale Jr. at the outset of the American Civil War to become an officer in the Union army. After completing his service, Halbert sought out his former employee James Sargent and decided to finance his company, creating what we know today as Sargent & Greenleaf.
The above 7 minute video gives a brief history of the evolution of the company from it's roots.
It is interesting to see in the video, some of the products that Sargent & Greenleaf produced, many of which are still in operation today in the field. Products like the reversible panic exit device, door security bolts, entrance door hardware, push/pull plates among others.
Below find a 15 minute industrial video from the 1950's that shows the production of Sargent & Greenleaf products.

Unlocking Antique Furniture Locks
Antique furniture locks come in all shapes sizes and styles. Often people lose their keys when the pieces are locked. As a locksmith, I have been called upon numerous times to open and make keys to these antique furniture pieces.Many antique furniture pieces including curio cabinets, use really old hardware made from brass and iron. Many of the locks are small and can be rusting.
The most efficient and easiest method for opening a locked drawer or door, is to impression a new key to the lock. The impression system of key fitting is the one skill that is unique to locksmithing.
Impressioning is used daily by few locksmith technicians these days and the art and talent is diminishing.
Impressioning enables the use of a keyblank, some hand files and some practised techniques to produce working keys to locks without the need to dismantle the piece of furniture. Largely, there is also rarely any damage to the woodwork, which is a good thing, because this maintains the value of the piece.
How does one impression an antique cupboard lock?
- Select Key blank
- Cut down flag to enter keyway.
- Blacken the flag (with carbon or a match)
- Insert key into keyway and turn as far as it will go.
- Turn and wiggle key numerous times.
- remove key from keyway
- Examine keyblank for "impressions"
- File minimally, where the impressions occur on the keyblank
