British Standard Locks and Insurance Compliance
Every lock we fit meets or exceeds BS3621 standards, which is the benchmark required by UK home insurance policies. We supply locks from trusted manufacturers including Yale, ERA, Avocet, Brisant and Ultion, and we can recommend the right option based on your door type, security needs and budget. Need a new lock fitted from scratch? See our lock installation and repair service.
We understand that needing a lock change can sometimes be stressful - especially after a break-in or if you are concerned about security. If you have been locked out of your home, we can gain entry and change the lock in the same visit. That is why we aim to make the process as smooth and straightforward as possible: clear pricing upfront, fast professional work, and a tidy finish with your new keys in hand.

Got Questions?
Lock Change FAQ
Common questions about our lock change service in London.
How much does a lock change cost in London?
Our lock changes start from £89 including a British Standard lock and 2 keys. The exact price depends on the type of lock and door, but we always give you a clear quote before starting. There is no call-out fee.
How long does a lock change take?
A straightforward lock change typically takes 15 to 30 minutes. More complex jobs, such as changing a multipoint lock mechanism, may take a little longer. Your locksmith will give you a time estimate when they assess the job.
Should I change locks when moving into a new home?
Yes, we strongly recommend it. You have no way of knowing how many copies of the existing keys are in circulation - previous owners, tenants, tradespeople or neighbours may still have access. A full lock change costs very little compared to the peace of mind it provides.
Do you supply the new lock or do I need to buy one?
We supply the lock. Our locksmiths carry a full range of British Standard cylinders and locks in their vans. You do not need to buy anything in advance - and our supply prices are competitive with retail.
Will the new lock work with my existing keys?
No. A lock change means fitting a completely new lock mechanism with new keys. This is what ensures your security - the old keys will no longer work. You will receive 2 new keys as standard, with additional copies available on request.
What types of locks can you change?
We change all types of door locks including Yale-type rim cylinders, 5-lever mortice deadlocks, euro cylinders (on uPVC and composite doors), multipoint locks, and night latches. Whatever your door has, we can replace it.
