Key fobs are great to have, but the batteries can be an inconvenience when they stop working.
Here is what you need to do to change a Mazda CX-5 key battery:
  • Press the auxiliary key button on the back of the fob to take out the metal auxiliary key
  • Carefully pry open the fob case with a flathead screwdriver, starting from one of the side slots and working your way around slowly
  • Remove the case and keep it in a clean, dry space
  • Remove the battery cap and battery without damaging the rubber ring
  • Insert new battery negative side down, replace the battery cover, fix the sides of the fob case, and re-insert the auxiliary key
