· Is it a fire door?
· What elements are required to ensure the safety of building users?
· What size is needed?
· Is a rebate kit required for a double door application?

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?
Rebate kits are an additional accessory that allows a mortice lock to be used on rebated double doors. UNION has a range of sizes and finishes available.

What is the safest lock for a front door?
The safest lock for a front door is a deadlock. This is a dead bolt that is moved by turning a key or thumbturn without the use of a spring. Deadbolts are heavier and thicker than standard spring latches and are usually made from steel or brass.
Aside from this, ensure that any solution you choose has been attack-tested and meets all the relevant standards.

Why does my door lock have two parts?
The smaller bolt is the latchbolt which is designed to locate in the strike plate hole on the door frame. The latchbolt retracts and projects by depressing kever handles or turning a thumbturn. The larger bolt is the deadbolt which is designed to only retract or project manually. This can be done by using a key or thumbturn.

Can you use an old deadbolt and door handle on a new door?
Yes, most locksets can be taken off any door and installed on any other door as long as they are the same type and function. We would recommend checking the case size, backset and centres (if applicable) before buying a new lock.

How do you secure your front door with secure locks?
If security is the main priority, the safest approach may be to upgrade a front door with a high security lock or sashlock to BS3621:2007. This standard is accepted by most insurance companies as the locks or latches are rigorously tested. A lock must exceed a minimum level of performance in all performance related categories such as durability, corrosion, security etc.
