High security rating

The Yale M552 5 Lever Dead Lock is a high level security solution designed for wooden doors. The 5-lever mechanism offers increased resistance against unauthorized access, providing reassurance when leaving your property unattended.

  • Peace of mind

    • This dead lock is operated by a key from both sides of the door and requires handles on each side
    • Comes with a 2 year guarantee.

5 levers

Compared to a lock with a lower number of levers, a five-lever dead lock offers enhanced security for external doors. The extra levers make the lock more difficult to pick and provide a greater number of possible key combinations.

  • How a five-lever lock works

    • Smart Lever System: When you insert and turn the correct key, it lifts five internal levers into the exact positions needed to unlock the door.
    • Secure Bolt Action: Once everything is perfectly aligned, the lock’s bolt slides open or closed, letting you safely access your home.
    • Extra Protection: Compared to a three-lever lock, the five-lever design offers much stronger resistance against tampering or picking—giving you greater peace of mind.

Secure and protected

This dead lock requires two door handles and is designed to work with bolt-through door handles, meaning your handles are firmly attached without needing extra screws. Available in a variety of finishes and colours to match your home’s style. 

 

  • Includes two keys as standard

    You’ll receive two keys with your lock, so you have a spare right from the start.
