How to change the Acura RDX fob battery
- Slide out the mechanical key if the fob has one, and look for a slot or notch along the seam.
- Twist a coin or a small flat screwdriver in the slot to split the case. Work around the seam rather than forcing one point.
- Note which side of the old cell faces up, then lift it out with a fingernail or plastic pick - avoid metal tools across the contacts.
- Fit the new CR2032 the same way up, snap the halves together, and test the lock button before walking away from the car.
