Utilize a prying tool to thoroughly separate the halves of the old shell. The majority of shells are either held together by a single small screw (typically hidden behind a logo design or the battery cover) or are "snap-fit." Apply even push to prevent breaking the internal circuit board.
3. Drawing out the Electronics
Once the shell is open, remove the battery and the PCB. Deal with the PCB by its edges. It is essential to determine the transponder chip. In many secrets, this is a separate, little black rectangle-shaped piece or a glass vial tucked into a corner of the shell.
