New homeowners, customers who want to change their home or business locks for better security usually wonder what is the difference between changing the locks and rekeying locks.


First, a general explanation what rekeying a lock means.


When a locksmith rekey a lock –


It means that you keep the existing lock, but changing only the key.

Therefore, the old keys won’t work, but you still get to keep the same lock you had.

In addition, you can choose to have all locks operated on the same key, giving you the convenience of having only one key.

When can locks be rekeyed to the same key and when they must be changed?

The only way to rekey two locks to the same key is when they have the same keyway.

The keyway of the lock is determined by the lock manufacturer. E.g. Kwikset locks and Defiant can be rekeyed to the same key because they have the same keyway.

However, when locks have a different keyway, e.g. Schlage and Kwikset, they cannot operate on the same key and therefore one of the locks must be changed.

When should I rekey my locks?
We recommend calling a locksmith to rekey your home or business locks in the following situations:
  1. First, when you moved into a new home or business. Most times many contractors had the key to the house to perform some work and therefore it would be wise to rekey the locks
  2. Lost keys – in cases where you lost your key. Since someone may have gotten your keys, it would be wise to rekey or change the locks. A Very similar situation where someone has your password for your email account – it is a smart move to change it.
  3. Upgrade your home or business security – in cases where you are worried about your home or business security and would like to have a better security system or have better control on who has and can gain access to your property
  4. Divorce, separation etc. – in situations of divorce, where the other party have the key to gain access, it is recommended to rekey the locks to make sure you are the only one who has the key to get into the property.

What a locksmith actually do when he rekey the lock?

The process is pretty simple one. The core of the lock is taken out and instead of the pins that are currently there are taken out and replaced by new ones.

Thus, the old key won’t “fit” to the new “code” created by the new pins.

A locksmith will provide a new key that fits the new code and therefore unlock the lock.

Furthermore, when the locksmith matches the key for a few locks, he inserts the same code, or use the same pins for all the locks and therefore the same key will operate them all.
