Published availability and qualifications
Verified in the 2025 U.S. Mazda CX-30 digital owner's manual for the factory transmitter; it is not presented as a package-specific function.
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
Press the transmitter's Lock button four times within three seconds.
- 02
Confirm that the key operation indicator illuminates.
- 03
While that indicator is illuminated, press and hold Lock for at least two seconds.
- 04
Wait for one hazard-light and warning-sound confirmation; passive key detection is now suspended.
- 05
Repeat the same four presses and two-second hold when you want to restore normal passive operation.
Important limits
- The transmitter buttons still work, but passive advanced-keyless entry and starting with the key left in a pocket or bag do not work in this mode.
- The key operation indicator does not illuminate or flash while power-saving mode is active.
- This is a reversible storage setting, not a substitute for replacing a depleted key battery.
Quick checks.
- ✓If the vehicle gives no confirmation, finish all four Lock presses within three seconds and begin the hold while the indicator is lit.
- ✓If passive entry still works, repeat the complete sequence because the toggle was not accepted.
- ✓If the vehicle cannot detect a stored key, turn power-saving mode off before assuming the key is defective.
