2.1.2. Master key
The master key opens and closes locks belonging to the same group or series (like the user key). The master key is used to open a
locker if a key has been lost, so the customer can be attended to immediately.
The letter W in the key number indicates that it is a master key.
If a user key is lost or missing, it is recommended to change the cylinder as a security measure to prevent theft or inappropriate
use. (See remove key).
STEPS FOR THE PROPER USE OF THE MASTER KEY.
1.
Insert the master key.
2.
Turn the key.
