Lock re-key or replace

re-key your home or office keys

In this article, we are going to explain what is the difference between rekeying a lock vs replacing it. This is one of the most popular locksmith services, and some people may think that this is an old school and locks are cheap, and you can buy a new lock anywhere, not like a long time ago, but this is not really true.

People still call us for that type of service, and yes it is one of our favorites because we love to bring back to life some old antique lock, with a lost key, or even rekeying a house for a new homeowner, who wants to replace the locks but can’t afford new locks after making the biggest investment in their life.

That is where the rekey service gets so efficient and is preferable for most clients on the market.


Re-key is the process of making a new key to the old lock, by changing the key combination and re-pinning the lock. This is a standard procedure, for example when a manager gets terminated usually we come out and rekey every single lock on the store. Or when the tenants moved out, we change the key and give it to the new tenants.

Most of the time this service is been used when you need to have one key for all the locks, instead of different keys for every single lock. At Cobra Locksmith we can make all the locks on your home key alike, by rekeying them all and providing only one key that opens all doors. This is very convenient for our customers.

But this service also can be used if the lock is not working properly, or the key that you have is worn out so much, that can not turn the lock anymore. In a situation when the key goes in the cylinder, but can not turn it, that means have to do something either with the key cuts (maybe a bad key), or some of the pins in the lock are stuck. Easily that can be fixed by rekeying the lock cylinder, and a new key by code is made.
