Changing your locks is one of the most effective ways to improve your home security. But when exactly do you need a lock change locksmith, and what does the process involve? This guide covers everything you need to know.
When Should You Change Your Locks?
There are several situations where changing your locks is strongly recommended:
- Moving into a new home: You never know how many copies of the previous keys exist
- After a break-in: Your existing locks may be compromised or damaged
- Lost or stolen keys: Anyone who finds them could access your property
- After a relationship breakdown: Ensure ex-partners or former housemates no longer have access
- Worn or damaged locks: Old locks are easier to pick or force
- Upgrading security: Replacing old locks with BS3621 certified models
What Type of Lock Should You Choose?
The right lock depends on your door type and security requirements:
- 5-lever mortice deadlocks — the gold standard for timber external doors
- Multipoint locks — ideal for UPVC and composite doors
- Night latches — convenient for everyday use, best combined with a deadlock
- Smart locks — keyless entry with smartphone control
