Need a reliable locksmith in London? Watchdog Locksmiths provides emergency and planned locksmith services for homeowners, tenants, landlords, property managers and businesses across London. Whether you're locked out, have lost your keys, need a faulty lock repaired or want your locks changed, our experienced DBS-checked locksmiths provide practical assistance with no call-out fee.
Our London locksmiths deal with a wide range of residential and commercial lock problems, including emergency lockouts, lock repairs, lock replacements, lock changes, snapped and stuck keys, uPVC door lock repairs, failed multipoint mechanisms and burglary repairs. From period houses and converted flats to apartments, rental properties, shops and commercial premises, we'll assess the lock and door before explaining the appropriate solution.

Emergency Locksmith London – 24 Hour Help

If you're locked out in London, have lost your keys, snapped a key inside the lock or have a door that suddenly won't open, our emergency locksmith London service can help. Where appropriate, our locksmiths aim to regain access without causing unnecessary damage to the existing lock or door.
Our 24 hour locksmith service in London is also available when a lock fails unexpectedly or a property needs securing following a burglary or attempted break-in. Once the immediate problem has been resolved, we'll check the lock, cylinder and door mechanism and explain whether any further repair or replacement work is needed.

Locked Out of Your House or Flat?

Being locked out of your home doesn't automatically mean the lock needs to be drilled or replaced. The correct method of entry depends on the lock, door and reason you're unable to gain access. Our locksmith will assess the situation first and use an appropriate method to regain entry wherever possible.
If the lock itself has failed, we'll explain what's wrong and whether it can be repaired or needs replacing before additional work is carried out.

Lock Repair London

If your lock has become stiff, the key is difficult to turn or your door is becoming unreliable, our lock repair service in London can help identify the cause. We work with common residential and commercial locks including Euro cylinders, mortice locks, nightlatches and uPVC multipoint locking systems.
Not every faulty lock needs replacing. Where an existing lock can be repaired safely and returned to reliable operation, we'll discuss that option first. Addressing a sticking or unreliable lock before it fails completely can also help avoid an unexpected lockout later.

Lock Replacement & Lock Changes in London

When an existing lock is damaged, badly worn or no longer suitable, Watchdog Locksmiths can provide a suitable lock replacement in London. We'll assess the door and current locking system before recommending the appropriate replacement.
We also carry out lock changes in London following lost or stolen keys, moving home and changes of tenancy. For landlords and property managers, we can assist with planned lock changes and access problems across rental properties.

uPVC Door Lock Repairs

A uPVC door that won't lock properly doesn't necessarily need an entirely new locking system. Problems can develop with the Euro cylinder, gearbox, multipoint mechanism or the alignment of the door itself. Symptoms can include a stiff handle, a key that won't turn or locking points that fail to engage.
Our locksmiths can inspect the complete system, identify the fault and recommend the appropriate uPVC door lock repair or replacement without unnecessarily replacing components that are still working correctly.

Commercial Locksmith London

Watchdog Locksmiths also provides commercial locksmith services in London for shops, offices, landlords, property managers and other business premises. We can assist with commercial lockouts, broken or unreliable locks, planned lock changes and other door access problems that affect the security or operation of a premises.

Burglary Repairs & High-Security Lock Upgrades

If your property has suffered a burglary or attempted break-in, our London locksmiths can inspect damaged locks, cylinders and door mechanisms and carry out the locksmith work required to secure the property again.
Where an older Euro cylinder needs upgrading, we can also fit higher-security options including the Watchdog 3 Star ALPS Euro cylinder lock, with TS007 3 Star security, a BSI Kitemark and anti-snap protection. If you're upgrading locks because of home insurance requirements, always check the specific requirements stated in your individual policy.

London Locksmith Case Study – Access Problem at a Period Conversion

A customer living in a period conversion near Caledonian Road contacted Watchdog Locksmiths after the communal front door lock had been changed by the building management without notice. Their existing key no longer operated the new cylinder, leaving them unable to access the building.
Our locksmith attended that evening, assessed the newly fitted cylinder and cut a replacement key for the customer, restoring access to the communal entrance without replacing the new lock.

How Much Does a Locksmith in London Cost?

The cost of a locksmith in London depends on the type of problem, the lock involved and whether replacement parts are required. Gaining entry during a straightforward lockout can involve different work to repairing a failed uPVC mechanism, replacing a damaged mortice lock or changing several locks at a property. Watchdog Locksmiths charges no call-out fee and will explain the work required before proceeding.
