Utilize a prying tool to carefully separate the halves of the old shell. A lot of shells are either held together by a single little screw (often hidden behind a logo or the battery cover) or are "snap-fit." Apply even push to prevent breaking the internal circuit board.
3. Drawing out the Electronics
When the shell is open, get rid of the battery and the PCB. Manage the PCB by its edges. It is vital to recognize the transponder chip.
