How a Lock is Re-keyed

When a lock is rekeyed, the mechanical locking mechanism is changed to ensure that previous keys will no longer work to open the lock. The lock is then reset to open with a completely different key. During a rekey, no hardware is replaced, as the only the internal component of the lock that rejects or accepts the key is modified. If you’re looking for a cost-effective way to change keys on any rental or business property, call us first.

Lock re-keying is recommended in the following situations:

  • Keys are unreturned, lost or stolen
  • Multiple locks need to work with the same key
  • New tenant in a leased property
  • New service or cleaning company
  • New building owner wants to limit the use of old keys

Frequently Asked Questions
About Lock Rekeying

  • Do I need to change all the locks if my keys are stolen?

    If your keys are stolen, you have two options: change the lock set or have it rekeyed. Replacing the lock set means that your entire lock, including the knob or handle, will be removed and replaced. Rekeying the locks only involves replacing the tumbler. You can keep the same hardware and lock, but a new key will open it and the old key won’t work. Read more about Great Valley Lockshop’s commercial rekeying service.

  • Do I need to change my locks or just have my existing locks rekeyed?

    Changing a lock requires replacing the whole lock, knob or handle, and hardware. When a lock is rekeyed, we change the existing cylinder and leave the rest. Your old key will no longer work and we’ll supply a new one. Read more about Great Valley Lockshop’s commercial rekeying service.
