As professional locksmiths with years of experience, we've seen it all — from simple lockouts to sophisticated burglaries. Here's our expert advice to help you keep your home and family safe.
Lock Maintenance Tips
- Lubricate locks annually — use graphite powder or a PTFE-based lubricant (not WD-40, which attracts dirt)
- Check for wear — if your key is getting harder to turn, get the lock checked before it fails completely
- Inspect door alignment — doors that have dropped put stress on locks and can cause premature failure
- Replace worn keys — a worn key can damage the lock mechanism over time
Home Security Essentials
- Fit BS3621 locks on all external doors
- Use anti-snap cylinders on uPVC doors
- Secure all ground floor windows with secondary locks
- Install security lighting around the perimeter
- Consider a burglar alarm and CCTV
When to Call a Locksmith
- You're locked out of your home, office, or car
- You've lost your keys (change locks immediately)
- You've moved into a new property
- Your lock is stiff, damaged, or not working properly
- You've been burgled or had an attempted break-in
- You want to upgrade your security
Choosing the Right Lock
The right lock depends on your door type and security requirements. Our locksmiths can advise on the best option for your specific situation. As a general guide:
- Wooden doors: Five-lever mortice deadlock (BS3621)
- uPVC doors: Anti-snap euro cylinder with multipoint lock
- Composite doors: High-security euro cylinder
