Fire Brigade Keys (FB Key Series)

Fire Brigade (FB) keys and locks are used by emergency services, councils and facilities teams throughout the UK.
They are most commonly associated with areas covered by the London Fire Brigade but are widely used nationwide.

Fire Brigade keys are typically fitted to locations where emergency services may require rapid access, including:

Gates and external access points
Gas and electrical cupboards
Dry risers and service risers
Plant rooms and communal areas

There is no single standard Fire Brigade key.
The term “Fire Brigade key” refers to a range of different keys within the FB series, each designed for a specific type of lock or application.

Drop Key

The Fire Brigade drop key is commonly used on automated gates and front entrance doors to allow emergency services access in the event of an emergency.
It is also sometimes used as an override key on lifts and elevators.

Important: In recent years, several new variations of the Fire Brigade drop key have been introduced.
Please ensure the key you select matches the images shown above before placing your order.
