Why Choosing the Right Lock Matters
Your door lock is the first barrier against burglars. Even the sturdiest door material won’t keep your home safe without a reliable lock. A proper locking mechanism:
- Prevents unauthorized entry
- Meets insurance and safety standards
- Offers peace of mind for you and your family
Understanding UK standard door dimensions can also help ensure your chosen lock fits properly and functions correctly.
Common Types of Locks on a Door
1. Deadbolt Locks
Deadbolts are among the most secure locks and are widely used on exterior doors.
- Single Cylinder Deadbolt: Key operated on the outside and a thumb turn inside.
- Double Cylinder Deadbolt: Requires a key on both sides, ideal if you have glass panels near the door.
- Lockable Thumb Turn: Offers flexibility to lock/unlock from inside with a key.
Deadbolts are often chosen as a second lock on a door for extra security.
2. Euro Cylinder Locks
If you’re asking what type of lock is on a uPVC door, the answer is usually a euro cylinder lock. These locks are fitted into a multipoint locking system securing the door at multiple points.
Why Euro Cylinders?
- Easy to replace without changing the entire door mechanism.
- Available in high-security versions like anti-snap, anti-bump, and anti-pick.
- Compatible with both uPVC and composite doors.
For composite doors, the euro cylinder is also the go-to option. Knowing what type of lock is on a composite door helps when upgrading or maintaining your home security.
3. Mortice Locks
Mortice locks sit inside the door and are common in wooden doors, especially older homes.
- 3-lever mortice locks are usually for internal doors.
- 5-lever mortice locks meet insurance standards for external doors (look for BS3621 certification).
They are very durable and often combined with other locks like night latches or deadbolts.
4. Night Latch (Yale Lock)
Night latches automatically lock the door when it shuts, providing quick security.
- Easy to operate from inside.
- Can be deadlocked with a key.
- Often used alongside mortice or deadbolt locks.
Adding a night latch is a practical way to install a second lock on a door.
5. Multipoint Locks
Multipoint locking systems secure the door at several points—top, middle, and bottom—usually activated by turning one key or handle.
- Common on composite and uPVC doors.
- Increase door strength and security.
- Often incorporate euro cylinders.
Multipoint locks are highly recommended for modern exterior doors.
What Type of Lock for a Second Lock on Door?
For enhanced security, many homeowners add a second lock on a door. The most popular choices include:
- A deadbolt lock: Provides an extra layer of strong security.
- Night latch: Quick locking and easy to use.
- Chain lock or security bar: Adds protection while allowing limited door opening.
Choosing the right second lock depends on your door type, usage, and security needs.
