Most homes have multiple external doors — but not all of them have locks of the same strength. And that’s a problem.
Burglars don’t attack your strongest lock — they attack your weakest.

This is why ensuring consistent lock grades throughout your property is essential.

🔍 What Are Lock Grades?

Lock grades are security ratings that determine how resistant a lock is to forced entry. For UK homes:

🔐 BS3621 is the required standard for wooden external doors
🔐 TS007 3-Star or Sold Secure Diamond for euro cylinders

These ratings indicate high resistance to snapping, drilling, picking, and bumping.

🚪 Why Mismatched Locks Create Vulnerabilities

If your front door is secure but your back door isn’t, burglars simply bypass the stronger lock.

Common weak points include:

🚪 Back doors
🛖 Side garage doors
🪟 Conservatory entrances
🔑 Old or budget cylinders

🔐 Which Locks Should Meet Insurance Standards?

For full coverage, insurers may require:

✔️ BS3621 mortice locks
✔️ Multi-point locking systems
✔️ Anti-snap euro cylinders
✔️ Approved window locks

If one entry point fails to meet these standards, claims may be rejected.
