ABOUT US
Real locksmiths. Real vans. Real fast.
We are a UK locksmith firm that runs 24/7. If you are locked out at 3am with a key snapped in the lock, a uPVC door that has decided it will not shut, or a door that has been forced, you need an actual locksmith on the line and a van at yours inside 20 minutes. A call centre passing the job to whoever is nearest is not the same thing.

Services
What we do
-
Emergency lockout
Locked out of the house, flat or office, at any hour. We bring the tools to open most doors without breaking anything and you are usually back inside in 15 to 30 minutes. Lines staffed every day of the year, bank holidays as well.
-
Lock change & upgrade
Lock worn out, cylinder snapped, or one that does not meet your insurer's BS3621 standard. We fit British Standard locks from brands you have heard of and finish most jobs in a single visit.
-
uPVC door repairs
Door will not lock, handle has dropped, or the multipoint has packed in. On uPVC doors it is nearly always the gearbox or the cylinder, not the whole door. We carry the common parts on the van and sort it the same day.
-
Burglary repair
After a break-in we get the door and locks back to a secure state. Forced cylinders out, damage looked at, BS3621 fitted, usually inside the hour from your call. Every van keeps British Standard hardware on board.
-
Safe opening & auto locksmith
Forgotten the safe code, lost the key, or the mechanism has seized. We open safes without damage where the model allows. We also cover most cars for lockouts, replacement fobs and ignition keys.

Call 0800 048 5569About the locksmith behind your call

James Carter has been fitting, repairing, and breaking into locks across the UK since 2008. What started as a sole-trader callout business in his home patch grew into a 24/7 nationwide service, now operating as SECURITY DOOR LOCKS LTD.
The customers who come back tend to come back for the same reasons: we arrive fast, the price quoted is the price paid, and the lock works when we leave. Every engineer on the team is DBS-checked, fully insured under our £5M public liability policy, and trained to British Standard BS 3621 lock specifications.
If you call 0800 048 5569 at 3am, it's the same business answering. Same engineers. Same prices. That's what seventeen years of running this looks like.
