Lock Re-Key and Master Re-Key for Your Home

Rekey Locks and Master Rekey

If you want to replace locks in your home, it may be cheaper to have the locks rekeyed by a locksmith instead. Rekeying is when the pins within the lock cylinder are replaced to fit a new key; that way any of the old keys won’t open the lock, and your new key will.

Rekeying locks yourself is not recommended, as you may damage or compromise the security of your locks. Locksmiths are professionally trained to rekey locks, so you should contact your local locksmith to request rekeying.

Master Rekey

You can also have your locks rekeyed so that one master key can open multiple locks of your choosing. Master keying involves installing what’s known as a spacer pin, or master wafer, between the key pins and driving pins in your lock.

After you’ve had your locks master rekeyed, your new master key is then able to unlock all the locks rekeyed for the master key system. The other keys, which you don’t want to have as much access within the house – known as change keys – are then only able to open locks which have been specifically rekeyed for them.

Cost to Rekey Locks

The cost to rekey house locks is usually between £50 and £70, depending on the type of lock. If you want multiple locks rekeyed that will inevitably cost more as you pay a fee for the additional time taken to rekey each lock. Roughly the same fees apply for a master rekeying service.

These are the average costs for specific lock types:

  • Garage door lock: £55
  • Internal door lock (bedroom/bathroom): £45
  • uPVC window lock: £55
  • Door handle: £55
  • Front or back door lock: £65
  • uPVC door lock: £65
  • Patio door lock: £65

    Excellent quick service! Lost my car fob 2 days ago. Which caused massive panic! Advised to phone Tony who came out to My work the next day and sorted the whole thing! Great service and great price! The Ford garage in comparison were very unhelpful and double the price! Thanks Tony!!

    Outstanding service. I phoned Tony, arranged a suitable time and day. He arrived when agreed and made a new car key within 30 minutes at an excellent price - much better value than anyone else in the area. Would highly recommend and will use Tony again in the future.
