Cencon ATM Security Lock - Error Code - When attempting to activate/shelve lock with SA key

Wrong key type 
The wrong key type has been presented. Make sure to use the appropriate key type for the appropriate function. 

Unable to Read SA Key information 
There is no information in the key, or the key has been bounced and the key is corrupt. If the audit count at the lock and the PC match, use combination. Otherwise contact Kaba Mas Customer Service get a close seal and try operation again with a re-programmed key.

Last audit record not “open" 
An attempt is being made to activate or shelve the lock but the last record showing in the Audit trail is not an “Open”. This might be caused by the bolt being extended before the Change Key is inserted. If the lock is in Shelved Mode, enter the Shelved Mode combination, retract the bolt, insert the Change Key and continue with the procedure. If the lock is active in another mode, close the call and have another call dispatched to open the lock and insert the Change Key and then continue with the procedure.

Lock mode already active/Shelved
The lock is already active or shelved in the mode you are trying to activate or shelve.
