Pliers (for flip key pin removal, if needed)

2. Dismantling the Old Shell

Use a prying tool to thoroughly separate the halves of the old shell. A lot of shells are either held together by a single small screw (often concealed behind a logo or the battery cover) or are "snap-fit." Apply even pressure to prevent splitting the internal circuit board.

3. Extracting the Electronics

When the shell is open, remove the battery and the PCB. Manage the PCB by its edges. It is important to identify the transponder chip. In lots of keys, this is a separate, small black rectangle-shaped piece or a glass vial tucked into a corner of the shell.
