BS8621 Mortise Locks Supplied and Fitted in Paisley and Glasgow

Looking to upgrade your home or property security with a BS8621-compliant mortise lock? A.L.S Locksmith supplies and professionally fits BS8621 locks across Paisley, Glasgow and the surrounding areas.

Designed to combine security with keyless escape from inside, BS8621 locks are particularly suitable for properties where occupants need to exit quickly without searching for a key.

What Is a BS8621 Lock?

BS8621 is a British Standard for thief-resistant locks designed to allow keyless egress from the inside while requiring a key to unlock the door from the outside.

Depending on the lock design, the internal release may operate through a thumb-turn, lever or other integrated mechanism.

These locks are designed to provide resistance to common forms of attack, including drilling, picking and sawing, in accordance with the applicable standard.

Why Choose a BS8621 Mortise Lock?

A BS8621 lock can be a suitable choice for properties where security and emergency escape are both important.

Benefits include:

  • Keyless escape: Exit from inside without needing a key.

  • Security from outside: A key is required for external unlocking.

  • Standards-compliant protection: Designed and tested to meet the relevant British Standard requirements.

  • Practical for multiple occupancy: May be suitable for flats, houses in multiple occupation (HMOs) and certain commercial premises, subject to the property's fire safety requirements.

  • Professional installation: Correct fitting helps ensure the lock operates as intended.

BS8621 is not simply a standard mortise lock with a thumb-turn added. The complete locking system must meet the applicable standard.

BS8621 vs BS3621: Which Lock Do You Need?

The main difference is the method of escape from inside.

BS3621 locks generally require a key to operate the deadlock from either side, whereas BS8621 locks provide a keyless internal escape facility.

The right option depends on your door, the property's layout, your insurance requirements and any applicable fire safety regulations. For shared accommodation and commercial premises, the escape arrangements should be assessed carefully before selecting a lock.
