The Zoo Hardware 3 Lever Mortice Deadlock in Silver is designed for securely locking internal timber doors. Its key benefit is offering reliable, key-operated security with a durable stainless steel finish, operable with a single turn of the key. A minor caveat is that it's sold individually, so you'll need to purchase multiple units if you intend to key alike different doors. This deadlock features a solid brass deadbolt and is a direct retro-fit replacement for existing locks, coming complete with a strike plate and fixings.

The deadlock itself fits into the door, with the latch case depth being 65.5mm (2.5") or 78mm (3"). The suitable door thickness will depend on your door's preparation for the mortice cut-out.
This deadlock is designed for internal timber doors and typically does not offer the weather resistance or security level required for external applications.
Two solid brass keys are included with each lock supplied.
Keyed alike means that multiple locks can be ordered so that they all operate with the same single key. This is convenient if you have several doors you wish to lock and unlock easily.
The mortice deadlock itself is generally reversible, but always ensure the strike plate is fitted to the correct side of the door frame for the direction the door opens.
The deadbolt is made of solid brass, providing durability and a good resistance to wear.
This specific product is described as having a silver, stainless steel finish. Other finishes might be available in different Zoo Hardware models.
Ensure the lock is correctly installed and aligned. Check for any obstructions in the keyway or bolt mechanism. Apply a small amount of graphite lubricant to the keyway and test again.
Verify that the strike plate on the frame is perfectly aligned with the deadlock bolt. Minor adjustments to the strike plate position might be needed. Ensure no screws are overtightened, causing the casing to warp.
Make sure you are using the correct key. Check for debris in the keyway. If the lock is newly installed, ensure the deadbolt is not catching on the strike plate or door frame.
This can sometimes indicate a loose component. Check that all fixing screws for the deadlock and strike plate are snug, but not overly tight, which could impede operation.
