Know what kind of control to look for.
This original category diagram is an orientation aid, not a picture of your exact trim. Use the written labels and your vehicle manual to identify the real control.
Step by step.
- 01
While safely parked, open Mazda Connect Settings and enable the walk-away or proximity auto-lock function.
- 02
Switch vehicle power off and exit with the registered key.
- 03
Close every door and the liftgate, then listen for the initial confirmation beep.
- 04
Walk beyond the key's operating range and listen for the second confirmation as the vehicle locks.
- 05
Check the lock status before leaving the vehicle unattended.
Important limits
- The vehicle may not auto-lock if another registered key remains inside.
- Leaving the operating range before all doors and the liftgate are closed can prevent the intended sequence.
- Do not treat the confirmation sound as proof that every opening is physically clear and fully latched.
Quick checks.
- ✓If only the first beep occurs, close every opening again and leave the operating range with the key.
- ✓If nothing happens, confirm that the function is enabled in Mazda Connect and that the key battery is healthy.
- ✓If the vehicle locks unpredictably, remove spare keys from the cabin and repeat the test with one registered key.
