Several features of the "No Tour" ibutton capability requires that the lock have the correct time. This ensures the following features will work as expected:

  • Orange Maintenance keys - these are written with access time down to the minute. They won't work if the lock's time is wrong.
  • Blue key No-Tour programming.
  • Key schedules
  • Expiration dates on blue or grey keys.
  • Anything relating to holidays or special events on CO/CT locks.
