Practical security expertise
The right lock for your door
We check the cylinder, handles, door alignment and multipoint mechanism before recommending a repair or replacement. A stiff door does not automatically need a new lock — and a failed cylinder does not mean replacing the whole door.

Straight answers
Frequently asked questions
How fast can a locksmith get to me?
It depends on where our locksmith is when you call, so we give you an honest ETA on the phone before you agree to anything — 24 hours a day across West London, Berkshire and Buckinghamshire.
Do you charge a call-out fee?
Your written quote sets out the total and what is included before dispatch. There are no surprise extras for the same agreed scope.
Will you damage my door or lock?
Non-destructive entry is our default. We try picking, latch bypass and other non-destructive methods first, so in most lockouts your existing lock keeps working. Drilling is a last resort and is explained before it happens.
How do I know what I am agreeing to?
Your written quote explains the agreed work and included charges before dispatch. You can ask us to confirm business and insurance details when you call.
What lock brands do you supply?
Yale, ERA, ABS, Avocet, Brisant Ultion, Mul-T-Lock, Ingersoll, Chubb, Banham, Union, GU, Fuhr, Maco and more — with availability confirmed for your job.
How much does an emergency locksmith cost?
Send a photo for a fixed written quote. We confirm the agreed work, quoted parts, labour and any call-out charge before dispatch. The price is 100% fixed for the agreed scope.
Are you open 24 hours?
Yes — we run a genuine 24 hour locksmith service, including nights, weekends and bank holidays. Calls go straight to a working engineer, not a call centre or a national dispatch board.
Can you cut keys while I wait?
Yes. We cut and copy house, padlock and mortice keys on the van, so key cutting is usually done on the same visit. Restricted and patented keys (Banham, ABS, Ultion) need proof of ownership before we duplicate them.
Can you repair a UPVC door that won't lock?
Almost always. A UPVC door that lifts but won't lock usually has a failed multipoint gearbox, a dropped hinge or an out-of-alignment keep. We carry gearboxes, cylinders, handles and hinges, so most repairs are finished in one visit rather than needing a whole new door.
Do you cover my area?
We are a mobile locksmith serving Staines-upon-Thames, West London, Berkshire, Buckinghamshire and nearby areas — including Harrow, Wembley, Uxbridge, Ealing, Slough, Reading, Maidenhead and High Wycombe. Check the postcode checker above or call and we'll confirm straight away.
