Important limits

  • A second registered key left inside can keep the vehicle from locking as expected.
  • Walking out of range before the last door or liftgate is closed can interrupt the sequence.
  • Always verify the lock instead of relying only on an audible signal.
If it does not work

Quick checks.

  • ✓If the vehicle does not lock, confirm every opening is fully latched and repeat the sequence without a spare key inside.
  • ✓If no initial beep occurs, check the Mazda Connect setting and the transmitter battery.
  • ✓If behavior changes after service, review the personalization setting because it may have been reset.
