Thumb Turn Mortice Lock – Keyless Egress Deadlock

The Thumb Turn Mortice Lock – also known as a Keyless Egress Lock, Thumbturn Lock, or Euro Thumbturn Mortice Deadlock – is specifically designed for doors that form part of a shared or communal area, particularly where fire safety regulations apply. Unlike traditional deadlocks that require a key from both sides, this lock provides keyless escape from the inside, making it ideal for multi-occupancy buildings and HMO properties.

Compliant with fire safety standards, this euro-profile deadlock is operated via a registered high-security key from the outside, while a thumbturn mechanism inside ensures easy and safe exit in an emergency. This design eliminates the risk of trapping visitors, tenants, or emergency personnel behind locked doors in shared entrances or hallways.

The lock can be keyed alike to existing systems, including rim, euro, or oval profile cylinders, making it an excellent choice for retrofitting additional security while maintaining single-key convenience for access control.
