Key Fob Battery Replacement Guide
Press and hold the mechanical release button on the side of the fob and remove the emergency key.
There should be a gap located on each side of the emergency key slot. Using your flat-blade screwdriver, carefully pry the cover until slightly open. From there you can use your fingers to separate the case completely.
Use the screwdriver to pry out the old battery, then insert a new battery with the positive pole facing up.
Place the lid back into position and snap shut.
