The Yale 89 Series Deadlocking Nightlatch in Grey is designed for homeowners seeking enhanced security for their front doors. Its primary benefit is the automatic deadlocking mechanism that engages upon closing, offering peace of mind. A potential caveat is the 60mm backset, which requires careful measurement to ensure compatibility with existing door preparations. This nightlatch is operated by key externally and a lever handle internally, featuring a snib function to hold the latch back and an option for internal deadlocking via key for increased security.

The backset is 60mm, which is the distance from the edge of the door to the center of the keyhole (or lock cylinder).
No, the internal deadlocking feature requires a reverse turn of the key from the inside to engage. The lever handle cannot deadlock it.
It is primarily designed for standard wooden or composite front doors. Ensure your door has the correct dimensions and pre-drilled holes for a 60mm backset.
Yes, the Yale 89 Series nightlatch is supplied with the necessary keys for operation, along with the 1109 Cylinder.
To use the snib function, push the bolt hold-back button (snib) and then close the door. This keeps the latch retracted and the door unlocked until the snib is released by opening the door or engaging the deadbolt.
While it enhances security, it's considered a nightlatch. For maximum security, especially on external doors, it is often used in conjunction with a separate deadbolt lock.
The deadlocking nightlatch automatically locks when the door is closed. A standard nightlatch may not automatically lock, requiring manual engagement for security.
Ensure the door and frame are aligned correctly and not sagging. Check that the deadlocking bolt is not obstructed and can fully extend. Verify installation is correct per manufacturer instructions.
Confirm the snib button is being pressed correctly before closing the door. Check for any debris or damage preventing the bolt from retracting and holding.
Ensure the correct key is being used. Try applying a small amount of graphite lubricant to the cylinder. Check for any obstructions in the keyway.
Verify that the internal deadlocking mechanism is not engaged. Check for any internal obstructions or damage to the handle mechanism. Ensure screws are not overtightened, binding the mechanism.
Setup: Installation typically involves removing the old lock, fitting the new nightlatch mechanism through the door, and securing it with the provided screws. Ensure the 60mm backset measurement matches your door's preparation. The 1109 cylinder should be fitted and the internal and external components connected.
Compatibility: This nightlatch is designed for standard wooden or composite doors. Compatibility is primarily determined by the door's thickness and the existing hole size. Crucially, the 60mm backset must match the distance from the edge of the door to the center of the lock cylinder. It is not designed for uPVC or metal doors without specific modifications.
Care: To maintain performance, regularly wipe the exterior with a soft, damp cloth to remove dust and grime. Avoid using abrasive cleaners, which can damage the finish. Periodically check that the latch operates smoothly; a small amount of graphite lubricant can be used if necessary, but avoid oil-based lubricants which can attract dirt.
