How to Avoid Locksmith Scams
Locksmith scams are unfortunately common. Protect yourself:
1. Check the address — Legitimate locksmiths have a physical business address, not just a mobile number
2. Get a price before they start — Reputable locksmiths quote before opening the door
3. Ask for ID — Master Locksmiths Association (MLA) members carry photo ID
4. Check reviews — Look for verified reviews on multiple platforms
5. Avoid "£1 call out" ads — These are typically bait-and-switch operations that charge hundreds on arrival
6. Save a trusted locksmith number — Find one before you need one
Frequently Asked Questions
Can a locksmith open my door without damage?
A skilled locksmith can open most locks non-destructively using specialist tools. If drilling is required (rare with modern locks), they should discuss this with you first and replace the lock afterwards.
What is a BS3621 lock?
BS3621 is the British Standard for door locks. Most home insurance policies require BS3621-rated locks on external doors. These locks are tested against drilling, picking and bumping attacks.
