Use a spying tool to carefully separate the halves of the old shell. Many shells are either held together by a single small screw (typically concealed behind a logo or the battery cover) or are "snap-fit." Apply even pressure to avoid cracking the internal circuit board.
3. Drawing out the Electronics
As soon as the shell is open, remove the battery and the PCB. Deal with the PCB by its edges. It is vital to identify the transponder chip. In many secrets, this is a separate, little black rectangular piece or a glass vial tucked into a corner of the shell.
