A mobile locksmith covering Bayswater and nearby W2 districts can replace or upgrade your locks. This covers front doors, back doors, internal doors and communal entrances. People change a lock for many reasons, such as a move to a new property, lost keys or a relationship breakdown.
Others change a lock at the end of a tenancy, or because the lock has grown worn, stiff or damaged. We remove the old hardware and fit a new cylinder or a complete lock case. Before we leave, we run a quick function test.
Yale nightlatch or mortice lock
Most UK front doors use either a Yale nightlatch or a mortice lock. A nightlatch is a surface-mounted latch with a separate cylinder. A mortice lock has a body set into the edge of the door.
A nightlatch is quicker to swap, because only the cylinder needs to change. A mortice lock often needs the whole lock case replaced. The right choice depends on the door thickness, the existing cut-out, and whether you want a deadbolt as well as the latch.
Repair or replace?
A lock that sticks does not always need a swap. A worn or misaligned mechanism can often be fixed for less. Our guide on how to tell if you need a lock repair or a replacement sets out the signs.
If the lock has been forced, snapped or drilled, replacement is usually the better route. Similarly, a lock that no longer meets your insurer’s standard should go. For the other path, see our lock repair page.
Upgrading to BS3621 at the same time
If your current lock does not meet the BS3621 standard, a lock change is the ideal moment to upgrade. Many insurers name BS3621, so your policy wording is the thing to check. A BS3621 lock also resists forced entry better. For a full guide to the standard and the models on offer, see our page on BS3621 locks.
Moving into a new flat or house
Changing the locks on move-in is standard practice for anyone who wants to be sure that no previous occupant or contractor keeps a key. It is a simple job, and we can usually finish it on the same day. You get peace of mind straight away, although the law does not oblige you to do it.
Landlords and letting agents
At a tenant changeover, landlords and letting agents often need a fast, documented lock change. You will find the process and any paperwork needs on our landlord lock changes page. For shared houses in particular, read about lock changes between tenants in an HMO.
Frequently asked questions
How much does a locksmith cost to change locks?
The price varies with the lock type and the number of cylinders. It can also change if you need extra hardware, such as a new keep or strike plate. For typical UK market ranges, refer to the locksmith prices London page.
How long does a locksmith take to change a lock?
A simple cylinder swap on a nightlatch can take under 30 minutes. However, a full mortice lock replacement may take longer, because the door needs preparation and alignment. Timing also depends on the time of day and the travel distance.

London labour rates and parts cost more than the national average. As a result, the total reflects the lock model and any extra fittings. See the locksmith prices London page for indicative ranges.
