Choosing the right locks for your building
When selecting locks for your building, there is so much to consider that it can be difficult to know where to start. Let us help you learn more.
What is the safest lock to have on a door?
The definition of ‘safest’ will change depending on what type of door it is. For example, if it is on a fire escape route, the safest lock is the one that will allow a single action means of escape, in the event of an emergency.
If security is the main priority, however, then the safest lock may be a extended 20mm deadbolt. This is because deadbolts are more robust than standard spring latches, therefore they cannot be easily manipulated.
What kind of lock should not be installed on a fire door?
Typically, any lock that isn’t fire rated to BS 476:Part 22, or EN 1634-1, and/or CE marked to the latest harmonised standard. For lockcases, this is EN 12209:2003.
How secure are electronic door locks?
Very. In fact, as most access control locks work with a traditional deadbolt, they are equally secure as traditional locks. They commonly use a form of access control via a key card, phone access, or mechanical key override – or request to exit buttons. Therefore, you will always be able to escape even in the event of any electronic failure.
How can you increase the security of a door lock?
Most locks have an element of security, however for high security requirements, we would recommend testing to BS 3621, BS 8621, or BS 10621. This standard not only meets the requirements of EN 12209, but it is also further rigorously tested against attack. This standard also includes GVA testing (General Vulnerability Assessment) which involves abuse testing and lock manipulation by experienced locksmiths.
What are the types of door locks?
There is a wide range of door locks available, including sashlocks, deadlocks, bathroom locks, latches, escape locks, nightlatches, deadlocking nightlatches, and rollerbolts and rollerlatches.
What are mortice locks?
A mortice lock is a type of lock that is fitted in to a hole within the door (called a mortice). Commonly used for timber doors, they are among the most popular lock types in the UK.
Is it theoretically possible to create a key that opens all locks?
In the world? No. There are simply too many locks in the world for one key to work with them all.
It is certainly possible, however, for one key to open all locks within a building or series of buildings. Master key systems help to maintain better control, save key replacement costs, and are highly convenient, as there are fewer keys in circulation.
What rebate kits are available?
An additional accessory that allows a mortice lock to be used on rebated double doors, there is a range of rebate kits available – depending on size and finish.
What type of door lock do I need?
To decide which door lock you need, it is necessary to ask yourself the following:
· What security level is needed?
· What type of lockcase do you need to suit the function of your door?
· Is it a fire door?
· What elements are required to ensure the safety of building users?
· What size do you require?
· Is a rebate kit required for a double door application?
