pextra PXP 1two3 Method
Construction keying is commonly used on site during the construction phase of building.
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.
