How to Replace the Key Battery on a Cadillac

Model: Cadillac Cadillac Various
Part: Key

A non-functioning key is not always broken; it may simply be a dead battery. In this case, the replacement is much simpler, quicker, and more economical. To replace the car key battery, first press the small button on the bottom to remove the physical key from the cover. Then, using the same key, gently push upwards to remove the rear cover. Just underneath is the button battery. Once replaced with a new one, correctly reposition the cover, and you're done.
