If the wrong code was input

The system is locked up for around 10 minutes if an incorrect code was entered three times. Another three incorrect inputs lock up the system for an additional 10 minutes. After another three incorrect inputs (i.e. after a total of nine unsuccessful attempts), the lock-up time increases to 60 minutes (this also applies to all further groups of three incorrect inputs). However, the emergency-call function of the PCM system always remains available.
