Cost to rekey locks

We all want to feel secure in our homes, and door locks provide one of the main security features for a property. Keeping your locks in good working order is therefore important, but that doesn’t mean you have to constantly replace the whole lock system.

In the guide, we look at the average cost to rekey locks in the UK. By rekeying your locks instead of replacing them you can save money and give new life to your existing door lock systems.

Rekeying locks is increasingly popular with landlords, who don’t want to change the locks every time they have a new tenant but still want to ensure their property is secure.

What is rekeying?

Rekeying a lock simply means changing the inner tumblers of the lock cylinder, so that old keys will no longer work. Think of it as the lock being re-coded to be able to accept a new set of keys instead.

It’s a fairly straightforward process for a locksmith to perform, and the cost to rekey locks is less than replacing the whole locks themselves. Once a lock has been rekeyed successfully, it will work with the new set of keys and you can throw away the old set, as they’ll then be useless.

How much does it cost to rekey locks?

The average cost to rekey locks on a house will depend on exactly which locks you need rekeying. An internal house door is the cheapest, with the cost to rekey being about £45 per lock. If you need to rekey a garage door, uPVC window lock or a door handle then the average cost is around £55 per lock.

The cost to rekey a front or back door lock, uPVC door lock or a patio door lock is in the region of £65 per lock. Though these prices will also depend on a number of factors.

Factors affecting the cost of rekeying a lock

  • Type of door / lock
  • Access to the lock
  • Any prep work needed
  • Where you live
  • Any emergency or out of hours work (locksmiths will charge a pretty hefty fee for emergency or out of hours work)
