Zadi AS cylinder extractor

Zadi AS high security cylinder extractor

With the lock open, insert the extraction key into the cylinder to be replaced, pressing it all the way down. In this way the last blade of the cylinder is retracted and it can be removed from the lock seat.

If you encounter difficulty in the operation, the cause may be dirt or damage to the seat caused by wear or bad intentions. In this case all that remains is to drill the cylinder, being careful not to damage the seat of the lock that houses it.
