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

The Latest Security News & Tips

Frequently Asked Questions
About Lock Rekeying

  • Can I rekey my apartment lock?

    Probably not without the landlord’s permission. Most common lease agreements indicate unequivocally that a tenant may not make improvements to the rented property without the authorization of the landlord and that the landlord must have access to the property. This is because, if the renter is not at home, a landlord with a key can let maintenance workers into the apartment to make necessary repairs. However, double-check your state's legislation to be sure. Tenants in California, for example, can alter the locks and refuse to share keys with their landlords.

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

    If your keys are stolen, you have two options: change the lockset or have it rekeyed. Replacing the lockset 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.
