24 Hour Locksmith in London: Emergencies We Attend

Most lock emergencies fall into a handful of situations. We carry the common locks, cylinders and tools for each, so the job is usually finished in a single visit.
◆

Locked Out of Your Home

The door pulled shut behind you or keys left inside. We use non-destructive methods wherever the lock allows, so you are back in without a new door or lock.

Non-Destructive First
◇

Lost or Stolen Keys

If someone else has your keys, they may have your address too. We change or rekey the locks so those keys stop working, then hand you new ones.

Lock Change
◈

Snapped or Stuck Keys

Half a key left in the cylinder or a lock that will not turn. We take out the broken piece, test the lock and only replace the cylinder if it is damaged.

Key Extraction
▣

After a Break-In

A forced door has to be secured tonight, not next week. We repair or replace the damaged locks and fit temporary protection until the frame is fixed.

Make Secure
▤

Failed uPVC and Multipoint Locks

Handle stuck, key will not turn, or the door will not lock after lifting the handle. We find the fault in the gearbox, cylinder or keeps and fix it on the spot where parts allow.

Gearbox & Cylinder Fixes
▥

Business Lockouts

A shop, office or unit that will not open, or will not lock at closing time. We get you in or secure it, and agree any repairs in writing first.

Getting You Back In Without Replacing Your Door

When you are locked out, the quickest option is not always the cheapest. Our locksmith identifies the lock first, checks whether it is deadlocked, then chooses the least damaging way in. If picking or bypass will work, we use it. If not, we explain why before drilling and fit a good replacement lock straight away.

From Emergency Entry to a Door You Can Trust

An emergency visit should never end with a door that the next person can open. Once you are inside, we check your locks and frame and tell you plainly what is worth upgrading. The decision is always yours.
✓

New Locks When Keys Are Gone

We change cylinders or locks straight away when keys are lost, stolen or copied, so old keys stop working that night.

✓

Locks Your Insurer Expects

Where your policy asks for a British Standard lock, we fit BS 3621 mortice locks on timber doors and TS007 3-star cylinders on suitable doors.

✓

12-Month Workmanship Guarantee

Every repair and every lock we fit is covered for 12 months, with a written note of what was done.

Emergency Locksmith FAQs

Clear answers on cost, call-out fees, damage, proof of residence and spotting a rogue locksmith.

A 2026 price guide puts a London emergency locksmith call-out at about £100 to £200 in the day and £160 to £250 at night, with an emergency lock change at £180 to £360 (Fantastic Services). We confirm our own price in writing before any work starts.

We never add hidden travel surcharges. Because an emergency visit involves travel and assessing the lock, we tell you on the phone how that part is charged and what the likely total is, so you can decide before a locksmith sets off.

We aim to reach lockouts across London as fast as traffic allows, and we give you an honest arrival estimate for your postcode when you call. If your property is insecure or someone vulnerable is locked out, tell us and we will put your job first.

Not usually. Most locks can be opened by picking or bypass, and we always try those first. Some deadlocked or high-security locks have to be drilled. If so, we explain why and agree the price of the replacement lock with you before we go any further.

Stop turning it and do not try to glue or force it, as that can jam the cylinder. Keep the broken piece if you have it. We extract the fragment, test the lock and only replace the cylinder if it is damaged, then cut or supply working keys.

Yes. A responsible locksmith must check you are entitled to enter. We ask for photo ID with a bill or letter showing the address, or a tenancy agreement or the agent’s permission if you rent. This protects you as much as anyone else.

Be wary of very low phone quotes that rise once the locksmith arrives, pressure to pay in cash and calls answered by a call centre. Which? advises checking reviews and accreditation first. We give a written price before work and our accreditations can be checked.
