Called at 11pm after being locked out. The engineer arrived in 18 minutes and had the door open in 5. Brilliant service, very fair price, and no hidden charges. Highly recommended.

What Our Customers Say
Had our UPVC lock repaired and upgraded to an anti-snap cylinder. Very professional — explained everything before starting, and left no mess. Will definitely use again.

Frequently Asked Questions
Everything you need to know about our locksmith services.
What locksmith services do you offer?
We offer a full range: emergency lockout, lock change and repair, UPVC and euro lock work, wooden door locks, lock upgrades to BS3621, domestic locksmith, commercial locksmith, and new lock installation. All services are available 24/7 with no call-out fee.
How much does a locksmith cost in the UK?
Prices depend on the service and time of day. Emergency lockouts start from £69. Standard lock changes start from £49. We always give you a clear, fixed price before starting — no surprises on the invoice.
Do you charge a call-out fee?
No. FastLockAssist never charges a call-out fee for any service, anywhere in the UK. You pay only for the work carried out.
How quickly can a locksmith reach me?
Response times vary by location — typically 15 to 45 minutes. Emergency lockouts are prioritised for immediate dispatch. Check your local city page for the specific ETA in your area.
Will my door be damaged during an emergency lockout?
In the vast majority of cases, no. Our engineers use non-destructive entry techniques — picking or bumping — which typically leave your lock and door frame intact. Force is only used as a last resort, and we tell you before doing so.
What parts do you use?
We carry British Standard (BS3621) approved cylinders and mortice locks on every van. All replacement parts are insurer-approved and come with a written guarantee. We never fit substandard parts without your knowledge.
Are your engineers DBS checked and insured?
Yes. Every FastLockAssist engineer holds a current DBS (Disclosure and Barring Service) check. We carry full public liability insurance, and all work is guaranteed in writing.
What is a BS3621 lock — do I need one?
BS3621 is the British Standard for thief-resistant locks. Most home insurance policies require a BS3621 mortice or cylinder lock on external doors. If your lock does not meet this standard, your insurer may not pay out in the event of a burglary. We can assess your current locks and advise you at no charge.
Can you help with commercial premises?
Absolutely. Our commercial locksmith service covers offices, retail units, warehouses, and multi-occupancy buildings. We fit high-security cylinders, access control systems, and master key suites. Out-of-hours emergency response is available for business customers.
Which areas of the UK do you cover?
We cover England, Scotland, and Wales, with engineers across hundreds of cities and towns. Use the city pages to find your nearest engineer and local phone number, or call our national line 24/7.
