Frequently Asked Questions

Can a broken door lock be repaired?

Often, yes. A locksmith can assess whether the fault is in the cylinder, latch, keyway or locking mechanism and repair the workable parts where appropriate. If the lock is badly worn, damaged or no longer secure, replacement may be the safer option.

When should I choose Door Lock Repair & Replacement London services rather than a simple repair?

Replacement is usually recommended when a lock is damaged beyond reliable repair, repeatedly fails, has been forced, or does not provide the level of security you need. Watchdog Locksmiths will explain the condition of the lock and the practical options before work begins.

How much does lock repair or replacement cost in London?

The cost depends on the type of door, lock, fault, parts required and whether security upgrades are needed. Watchdog Locksmiths has no call-out fee and can assess the issue before advising on the appropriate repair or replacement work.

Should I change the locks after moving into a new home or commercial premises?

It is sensible to change or rekey locks after moving in, as you may not know who has copies of the existing keys. A locksmith can review the doors and recommend suitable lock changes or security upgrades for the property.

What should I do if my key is stuck, snapped or the door lock is sticking?

Avoid forcing the key or repeatedly turning a stiff lock, as this can cause further damage. A locksmith can safely inspect the issue, remove a broken key where possible and repair or replace the affected lock if needed.

What types of locks can be repaired or replaced, and will they meet insurance requirements?

Watchdog Locksmiths can help with common residential and commercial door locks, including euro cylinders, mortice locks, night latches and multipoint locking mechanisms. Higher-security options, such as TS007 3 Star cylinders, may help meet common home-insurance security requirements, but you should check your own policy for its specific conditions.
