Geepas Double Cylinder Mortise Lock, 70mm, Anti-Drill Anti-Pick Security Lock

A double cylinder mortise lock has keys on both sides of the door, so you need a key to operate the lock from either side. This reduces the risk of intruders manipulating the pick or force-entry from inside the room.

This model is a 70mm mortise lock designed for standard 70mm backset doors. It’s built for door frames that accommodate a typical 70mm mortise bore and includes the necessary mounting hardware for straightforward installation.

The package includes 5 extra keys in addition to the primary set. If you need additional keys later, you can request extra copies through Fepy or the Geepas compatible key service.

The lock is constructed from corrosion-resistant zinc alloy, which provides durability and a clean aesthetic. This material choice supports longer life and reliable performance in typical door environments.

Installation involves aligning the lock body with the door bore, inserting the fasteners, and attaching the strike plate. The package includes mounting hardware and installation instructions. It’s recommended to follow the step-by-step guide and ensure the door is solid and properly prepared for a mortise lock.

Keep the keyways clean and free of dust. Use a graphite or silicone-based lock lubricant occasionally to reduce stiffness and ensure smooth operation. Avoid oil-based lubricants that can attract dust or gum up the mechanism.

This 70mm double-cylinder mortise lock is well-suited for front doors, apartment entries, home offices, and rental properties where enhanced security is desired due to the dual-key operation on both sides.

Compared with similar 70mm mortise locks on Fepy, the Geepas GHW65075 emphasizes double-cylinder security and an anti-saw feature, along with multiple keys and zinc alloy durability.
