How to Lock or Unlock the Mazda 3 Without a Remote

Model: Mazda 3 MK 4, BP - Years 2019-2026
Part: Key

If you need to open or close the vehicle when the remote key is not functioning, perhaps because the battery is flat, the following description provides the necessary information to perform this operation. Remove the rear cover of the remote to extract the emergency key, then tilt the door handle downwards, and underneath, you will find the slot for the standard key. You can then insert the emergency key and open or close the vehicle as normal.
