Common Door Lock Types Used in the UK – AMZ Locksmith

In the UK, most homes and commercial properties rely on a small number of proven, high-security lock types. At AMZ Locksmith, we work with every major lock system used nationwide, and we know exactly which locks offer the best protection, reliability and long-term value for our customers.

1. Euro Cylinder Locks

These are the most common locks found on UPVC and composite doors. They come in standard, anti-snap, and 3-star high-security versions. Anti-snap and 3-star cylinders are strongly recommended because they protect against common break-in methods such as snapping, drilling and picking.

2. Mortice Deadlocks (BS3621)

These are typically fitted on wooden front doors. A proper British Standard 5-lever mortice lock offers excellent security and is usually required for home insurance. It’s strong, durable and extremely resistant to forced entry when installed correctly.

3. Night Latches (Yale-type Locks)

Often combined with a mortice lock, night latches allow quick entry with a key and auto-locking when you close the door. British Standard night latches provide added strength and are ideal for improving security on timber doors.

4. Multipoint Locking Systems

Found on UPVC and composite doors, these systems lock at several points around the frame when the handle is lifted. They offer very high security when paired with a 3-star cylinder. Most issues can be repaired without replacing the whole system.

5. Rim Cylinders

These are the round cylinders used with night latches. They’re quick to replace and available in standard, anti-pick and high-security options.

6. Smart Locks

Smart, keyless, and coded locks are becoming increasingly common across UK homes and offices. When installed properly, they offer convenience and strong security, especially for rental properties and busy households.
