Use a spying tool to thoroughly separate the halves of the old shell. Most 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 press to prevent breaking the internal circuit board.
3. Drawing out the Electronics
Once the shell is open, remove the battery and the PCB. Manage the PCB by its edges. It is crucial to identify the transponder chip. In lots of keys, this is a different, small black rectangle-shaped piece or a glass vial tucked into a corner of the shell.
