What is a PZ?

The PZ or centres is the vertical distance between the centre of the keyhole, and the centre of the handle.

On a lock this will be measured from the centre of the keyhole to the centre of the follower (where the spindle of the handle will pass through the door).

On a handle this will be measured from the centre of the handle to the centre of the keyhole.

What dimension is the backset?

The backset is the dimension from the centre of the keyhole to the front of the faceplate of the lock.

This makes sure if you already have an existing lock fitted, then the dimensions will be the same, so you would not need to do any adjustment work to the door.

What is the difference between Keyed to Differ, Masterkeyed, and Keyed Alike?

Keyed to differ means that if you order 2 or more locks, then each lock would come with a different set of keys per lock.

Keyed Alike means that if you order 2 or more locks, the locks would all arrive with the same key.

Masterkeyed means that if you order 2 or more locks, both locks would come with different keys, and you would be able to purchase a ‘master key’, and this would open all of the locks.

What is British Standard mean?

British Standard locks are stamped with a kitemark, and these generally tend to be used for front doors, as in the event of a of a break in, these would be covered by your insurance (depending upon your policy), as well as the police.

Due to this nature, these often tend to have a few more security features as well.
