Double cylinders with key override

Double cylinders with key override

Key left in the lock? Not a problem!
The double cylinder makes it possible to open the door from the opposite side with an authorised key when the key is inserted on one side and rotated in any direction.

Your requirements:
You want to be able to open doors even if
a key is still inserted on the opposite side, e.g. if the front door shuts unintentionally.
Principle of operation:
If a key is inserted on one side of the door, the double cylinder enables the door to be unlocked from the
opposite side by another authorized key, regardless of the rotation of the first key, which turns with it. This function is guaranteed to work on both sides of the double cylinder.

These cylinders are made to order under a restricted key so duplicate keys must be purchased from the original purchaser.
Delivery from order is normally around 7-10 working days.

Pextra+ meets EN1303 Key Related Security Grade 6 and is a Kitemark Approved, TS007 1-star cylinder that protects against drilling, picking and bumping.
Pextra+ features a sophisticated, patented key profile, with a “branch groove”.
Duplicate keys cannot be made using commercial key milling machines.
The optional blocking pin verifies the presence of the branch groove.
If the original branch groove is not detected, the blocking pin prevents the key from being turned completely in both directions.
