After a security issue at your Buffalo NY business, you might be wondering whether to invest in master rekeying or a complete security overhaul. It’s a question that we know many of our Red Key LLC customers will face as business owners and we want to make the decision easier for you!
Let’s take a look at some of the benefits of commercial rekeying as well as situations in which this service is not recommended. And when you’re ready to call in the pros, we’ll cover everything you can expect from lock rekeying!

What is commercial rekeying?
Rekeying is a process by which a locksmith can alter the internal workings of a lock in order to correspond to a new set of keys. Here’s how it works:
- The locksmith removes the internal cylinder of the lock
- The locksmith removes the pins and springs that are calibrated to the previous key
- A new key is inserted into the lock so that the pins can be replaced according to that key’s configuration
- The cylinder is replaced back into the lock
This is typically a quick, simple solution to retire the old set of keys and introduce a new one. While a trained professional can complete this project in a matter of minutes, it does require a specialized set of tools and knowledge of how the lock cylinder functions.
When is rekeying necessary?
The first thing you may think of as a reason for rekeying is a security breach such as a stolen key. That’s because a key that has fallen into the wrong hands can be used to access your storefront, restaurant or warehouse with minimal effort.
But, even if you’re not dealing with key theft, there are a few other scenarios in which you may want to render the old set of keys unusable:
- You’re moving your business into a new commercial space
- You have had a staffing change
- One of your staff members has misplaced their keys






What is the difference between rekeying and master rekeying?
Whereas standard rekeying allows you to replace a single set of keys that correspond to a lock, what about systems that use a master key system?
Locks that have been configured to a master key system will use something called a master wafer or spacer that allows the master key to function on a variety of locks. This also allows for rekeying of the master key independently of the single keys that correspond to the individual lock.
In a more practical way it means that every employee can have have their own specific key to their office, while the owner will have one key that opens all of them.
That being said, if a master key is lost or stolen, that means that all of the locks that can be opened by the master key should be rekeyed as soon as possible to cut down on security threats.
What are the benefits of keying and master rekeying?
Rekeying can offer a preferable alternative to replacing the locks in your system. Here are a few reasons why:
- Rekeying is fast. A trained locksmith can rekey a lock within a matter of minutes. So, even if you have to rekey a number of locks, you’ll be able to restore your security in a reasonable timeframe. Having to order and install brand new locks, on the other hand, can be a days- or weeks-long process.
- Master rekeying saves you the headache of overhauling your system. Master key systems are supposed to make your life easier, not more complicated! And, rekeying a single level of key hierarchy can be much more logistically accessible than the alternative or replacing the locks.
- Rekeying is typically more affordable. Because rekeying doesn’t require additional hardware or changes to the door, it is a more cost-effective option than replacing your locks.






When is lock replacement preferable to rekeying?
While commercial rekeying can be an affordable, convenient option for your business, it’s not always the best one! Here are a few reasons why your local locksmith may recommend lock replacement over rekeying:
- The original key or change key has been lost. No matter if you’re rekeying a lock for a single key or a master key system, you need to have access to the original key or the change key in order to complete the process successfully.
- Your locks are worn down or damaged. If your current locks pose a security risk because they are no longer in good working condition, your locksmith will recommend replacement over rekeying.
- You could benefit from increased security. Maybe there has been a rash of lock-picking in your area, you want to switch over to a smart lock system, your business staff will be expanding. In these kinds of cases, replacing your locks could be the best move.
- You want to implement a master key system but your current locks aren’t compatible. In order to install a master system, your locks must be able to work together. So, a security breach may be the opportune time to get your locks aligned in order to install a master key system.
What kinds of locks can be rekeyed?
Most information on lock rekeying has to do with cylindrical locks, but rekeying can also be done on a variety of other design models! Mortise locks, emergency exit locks, sliding glass door locks, for example, can all be rekeyed.
