How to Replace the Battery in a Cadillac Car Key?

[StSarah]

Instructions for replacing the battery in a Cadillac car key: 1. Remove the mechanical key. Press the switch and then pull the mechanical key upward to remove it. 2. Pry open the key along the edge. Note: You can use your fingernail or a flat-head screwdriver, but you must apply gentle force. Avoid using excessive force, as there are six small clips inside that can easily be damaged. 3. Once opened, you will see the key split into two halves: one side contains the integrated circuit board, and the other side holds the battery. 4. Remove the old battery and install the new one. 5. Reassemble the key.
