FAQs

Is this lock suitable for external doors?

Yes, this Yale 5 Lever Deadlock is designed for both internal and external use on wooden doors.

Do I need to cut a hole in my door for this lock?

Yes, this is a mortice deadlock, which means a rectangular opening (mortice) needs to be cut into the edge of the door to house the lock case.

Can this lock be used on a UPVC door?

No, this lock is specifically designed for wooden doors and is not suitable for UPVC or metal doors.

How do I know if it's for a left or right-handed door?

This deadlock is designed with universal handing, meaning it can be fitted to doors that open to your left or to your right without any special conversion.

What is the difference between a 3-lever and a 5-lever lock?

A 5-lever lock offers a higher level of security than a 3-lever lock. It is more difficult to pick or force, making it a more robust security option.

How do I maintain the lock?

Keep the exterior clean with a dry cloth. For the internal mechanism, use graphite powder sparingly if the lock becomes stiff. Avoid oil-based lubricants.

Troubleshooting

Key will not turn

Ensure the bolt is fully retracted. Check for any obstructions in the keyway or if the mortice is too tight for the bolt.

Bolt is stiff or jams

Verify that the mortice is large enough and that no part of the door is binding the bolt. Clean the keyway and bolt with graphite powder.

Lock was difficult to install

Double-check the measurements for the mortice. Ensure the door is not warped and that the lock case fits snugly without forcing.

Key gets stuck

Do not force the key. Gently try to jiggle it while turning. Apply a small amount of graphite powder to the keyway.

Setup, Compatibility & Care Instructions

  3. Insert the deadlock body and secure it with the provided screws.

Compatibility:

Care:
