How to Change the Battery in a Cadillac Key Fob

The exact steps might differ slightly based on your Cadillac model year and key fob design. However, the general process is quite similar:

  1. Locate the Release Button or Notch: Examine your key fob for a small release button or notch. This is usually located on the back or side of the fob.

  2. Separate the Key Fob Halves: Press the release button or insert the flat-head screwdriver into the notch and gently pry open the key fob casing. Use a plastic pry tool if you prefer to avoid any potential scratching.

  3. Identify and Remove the Old Battery: Once the casing is open, you’ll see the battery. Carefully remove it by prying it out from its slot. Take note of the battery’s orientation (+/-).

  4. Insert the New Battery: Align the positive (+) side of the new battery with the corresponding marking in the compartment. Gently press it into place.

  5. Reassemble the Key Fob: Align the two halves of the key fob and press them together until you hear a click, indicating they are securely closed.

  6. Test the Key Fob: Check if the buttons are responsive and if the LED indicator lights up.
