Lock Replacement & Front Door Lock Changes in North London
Need to change your door locks after moving house, losing your keys or discovering a faulty lock? Lock Luxe helps customers in Hendon and nearby North and North West London find the right replacement.
From replacing a euro cylinder to changing a mortice lock, nightlatch or faulty multipoint mechanism, the work depends on your door and existing hardware. You don't need to identify the lock yourself — send a photo and your postcode.
Change the Locks on Your Front Door
A front door lock change isn't the same job for every property. Sometimes a cylinder can be replaced to give you new keys. Other times, the lock case, gearbox or complete mechanism needs attention.
Mortice Locks & Nightlatches
Traditional timber doors may use a mortice deadlock or sashlock alongside a Yale-style nightlatch. A worn lock case may require replacement, while a rim-cylinder change can sometimes provide new keys without changing the entire nightlatch.
Euro Cylinders & Multipoint Locks
A cylinder change can be suitable when you need new keys. If the handle won't lift or the door won't lock, a gearbox, locking strip or door-alignment problem may need attention instead.
Lock Changes & Security Upgrades
Composite doors commonly use euro cylinders with multipoint locking. Changing the cylinder may be enough for new keys or a suitable anti-snap upgrade; a failed mechanism requires a different assessment.
Locked out or unable to secure your door? Let us know straight away so we can discuss the urgency. See our emergency locksmith service for urgent lock and access problems.
What Part of the Door Lock Needs Changing?
Changing the entire lock isn't always necessary. These are common possibilities, but the correct solution depends on inspecting the existing hardware.
Euro Cylinder
The key-operated cylinder may be changed separately on many uPVC and composite doors, including when moving home or upgrading security.

A damaged or worn mortice case may need a compatible replacement. The door's measurements, security requirements and safe-exit needs matter.
Mortice lock typesNightlatch or Rim Cylinder
A Yale-style lock may need a new outside cylinder, a replacement latch body or other work depending on the fault and hardware.
Nightlatch replacementGearbox or Multipoint Mechanism
A stiff handle doesn't always mean the locking strip has failed. Door alignment, gearbox wear and the multipoint system should be considered.

Lock Fitting vs Lock Replacement — What's the Difference?
Replacing an Existing Lock
This means changing some or all of the hardware already fitted to your door. If you simply need different keys, changing a compatible cylinder might be sufficient. A damaged mortice case or multipoint gearbox is a different type of replacement.
Fitting a Lock Where There Isn't One
Installing a completely new lock can involve assessing the door, preparing the correct position and choosing suitable hardware. It's not the same as a straightforward lock change. Contact Lock Luxe to discuss whether the fitting you need can be provided.
Planning a security upgrade? For a suitable timber door, a British Standard BS3621 lock may be relevant to your insurance requirements. For doors using euro cylinders, anti-snap cylinder options involve different standards. Check your own policy and door requirements before choosing.
Why Do People Change Their Door Locks?
New Home, New Keys
You may not know who holds copies of the old keys. Changing the relevant lock or cylinder helps you control access without necessarily replacing all the door hardware.
Lost or Stolen Keys
If keys are unaccounted for, especially with anything identifying your address, replacing the keyed component may be sensible.
Faulty Hardware
A broken lock case or cylinder may require replacement. If the issue is repairable, our lock repair service may be more suitable.
Upgrading the Door
Discuss suitable rated locks, anti-snap cylinders or changes after a tenancy. The right option depends on the door and its existing fittings.
How Much Does It Cost to Change a Door Lock?
The cost of a lock change depends on the lock type, replacement parts, labour and whether the door opens and closes properly. A cylinder change is different from replacing a mortice case or multipoint locking system.

Front Door Lock Replacement FAQs
Can I change the locks on my house without changing the whole door handle?
Often, yes. On many doors, the cylinder can be replaced separately while the existing handle and sound locking mechanism remain in place. It depends on the lock type and condition.
Do I need to change my locks when I move house?
It can be a sensible precaution if you don't know who has copies of the keys. Changing a compatible cylinder or keyed lock may be enough; replacing all the hardware isn't always necessary.
How much does a front door lock change cost?
The cost depends on the lock, parts and work required. Contact Lock Luxe for a job-specific quote, or see our locksmith prices page for more information.
Can you replace uPVC and composite door locks?
Lock Luxe handles enquiries about euro cylinders, gearboxes and multipoint lock problems on uPVC and composite doors. The right replacement depends on whether the issue is with the cylinder, mechanism or door alignment.
What's the difference between a BS3621 lock and an anti-snap cylinder?
BS3621 is relevant to certain complete lock assemblies, commonly mortice locks; anti-snap protection relates to suitable euro cylinders and their security ratings. Check the requirements for your door and insurance policy. Read our BS3621 lock guide.
