Key 1 is the first key that is to be used in your cylinder/lock. Key 2 and Key 3 are reserved for the future.

General Use:

pExtra PXP can be used in both new fits and retrofits.
It is available in a wide range of different lock types, for example mortice locks, rim locks, padlocks, furniture locks, cam locks and many more.

The pExtra 1two3 system allows you to lose your keys up to 3 times before requiring a rekey. 
These rekeys can be built into the cylinder by the locksmith during the assembly stage of the cylinders using two special wafers.
When you lose your key for the first time, you simply insert your second key into the cylinder. By inserting this key the first wafer is moved into the side of the plug allowing the new key to work, which in turn blocks the first key from working again.
When you lose your second key, you simply insert your 3rd key into the cylinder. By inserting this key into the cylinder, the second wafer is moved into the side of the plug allowing the new key to work, which in turn blocks the second key from working again.

 

Construction Keying:

A convenient way of providing continued security during the 3 phases of construction is to use pExtra Construction keying.
In simple terms, all cylinders are operated by the one key (KA) during the construction phase.

At “handover” the next stage key (commonly known as the developer key) is turned in the cylinder, moving the 1st construction wafer, and “changing” the combination of the
cylinder to the key that has just been inserted. Blocking the Phase 1 key from working again.

Once the apartment is sold, to you as the owner you would insert your key into the cylinder and once the key is turned this moves the 2nd construction wafer, again “changing” the combination of the cylinder to the final combination, to your key. Blocking Phase 1 and Phase 2 keys from working again.
