When ordering multiple Keyed Alike locks, only 1 set of keys are provided as all additional locks are made to work from that key.

If ordering 4 or more keyed alike locks you can have them set up as different groups. If Required: Let us know the details in the "Specific Key Requirements" field above.

Each group of locks will then receive keys.

The Asec FB4 Slam Lock Key is a standard pre-cut key specifically engineered to operate FB4 fire brigade locks. These locks are typically installed on fire escape doors, communal entrances, and service cupboards in both residential and commercial buildings. The FB4 pattern is a standardised design used across the UK, allowing authorised personnel to access multiple sites using a single key type.

Typically used in slam lock configurations, this key is essential for facility managers, maintenance contractors, and emergency services. It provides a reliable method for accessing restricted areas such as plant rooms, dry riser cupboards, and meter rooms where immediate entry may be required during an emergency or for routine servicing.

This key is a direct replacement or spare for lost FB4 keys and is compatible with all FB4 pattern mortice locks regardless of the lock brand. It is constructed from robust materials to withstand frequent use in demanding environments, ensuring consistent operation of the internal lock mechanism.

FAQs

This is the most important point to get right so you don't leave your home vulnerable to attack. The best way to get the correct size is to remove the cylinder from the door. (see the help page for instructions to do this). Once you have the cylinder out the door you need to measure from one side of the cylinder to the center of the fixing screw hole and then the same from the other side. Make a note of which is the inside measurement and which is the outside. Once you have this you need to match the size to the sizes available online. You want to get this as exact as possible. The cylinder sizes go up in increments of 5mm.
