Cambridge Lock Rekey – What Is It ?

Lock rekeying is the process of changing the lock code. The lock is taken apart and the locking pins are replaced with new pins and springs, then new keys are cut to match the new locking pins. At this point the old keys will not operate the lock.


The reasons for rekeying a lock are many, but they should all revolve around security and key control. Let’s say that a bank has 5 keys that open the bank doors, when they do an audit it is discovered that they cannot account for one key. They have two choices: replace all the locks that the lost key opened or rekey all those locks. If the door hardware is in good condition then the choice should be to rekey. A locksmith can do this job at the bank and cut new keys to match the rekeyed locks.


Key control is the process of knowing where all your keys are and who has them. If you can’t account for even one then rekeying should be your first action. Remember, without Control you do not have a secure facility. Most quality locks can be rekeyed and if the lock happens to be high security, then when it is rekeyed you will get a new registered code with registered keys.Cambridge Lock Rekey


When Does ReKeying Make Sense?

  • Keys are lost
  • The cost of rekeying is very low when compared to new locks
  • The existing door hardware is in good condition
  • Need to have new keys for your locks very quickly
  • When the lock you are rekeying is considered high security
  • Need multiple locks to operate with the same key
  • Need to convert to a master key system


Rekeying has an advantage if you want to change the keying sequence of your building. For example, if you have multiple doors that work with a different key (keyed different) and you want these doors to all open with the same key (keyed alike). All of these locks can be taken apart and rekeyed so that they all open with the same key. To take this a little further you can create a master system. This is when all the doors open with different keys, but you have one (master) that will open all the doors.

So, as your needs change reKeying is an option to inexpensively change the lock codes without purchasing new locks. Rekeying also allows you to change your current locking system to a new system.


What Is Rekey?

Rekeying is the process of altering a lock so that it uses a different key. This is different from changing a lock because it that situation, the entire lock and accompanying hardware is completely removed and replaced. In rekeying, new keys are made and the existing lock mechanism is reset so that it will only open with the new keys.


The interior cylinder of a lock contains a series of upper and lower pins. When you insert a key into the lock, it pushes the pins into alignment, enabling you to open the door. To rekey a lock, a locksmith replaces the lower pins with ones that fit perfectly along the ridges of the new key. This way, only that key will unlock the door, even the old lock is still in place. It is a simple process that takes a skilled locksmith only minutes to accomplish.


Rekeying is recommended for security reasons any time you move into a new home, apartment or office space. Prior residents or tenants could have made duplicate keys without your knowledge and could easily enter any time they wish. This is also a wise precaution for business owners who have fired an employee who had access to company keys. Losing keys is another good time to have your locks rekeyed.
