Match aftermarket key fob case to the board

Key fob

Before you swap a cracked shell, match the aftermarket key fob case kit to your board and button layout so a fresh key fob battery still seats right.

A cracked shell tempts a quick case swap — but the board, pad, and key fob battery tray must match the kit or buttons feel wrong and the coin cell sits loose.

Match the aftermarket key fob case to your board

  1. Open the old shell carefully. Leave the circuit board and rubber pad stacked as they came out so you can photograph the button layout and battery tray.
  2. Compare the kit’s shell and pad to your photo: same button count and shapes, same battery tray opening (often a CR2032 clip), and the same board outline.
  3. Dry-fit the board and pad in the new shell before you discard the old case. The pad should sit flat and every button should press the right switch.
  4. Install a known-good coin cell only after the board seats without rocking. Then close the shell and test lock / unlock at a few feet.

If the kit’s pad has extra holes or a different tray, return it — do not force a mismatch.

Honest stop

Case kits do not reprogram a dead remote. If a matched shell and fresh cell still leave you with no range, see the battery-vs-dead-fob check before buying another shell.
