3. Extracting the Electronics

As soon as the shell is open, eliminate the battery and the PCB. Manage the PCB by its edges. It is vital to determine the transponder chip. In lots of secrets, this is a separate, little black rectangular piece or a glass vial tucked into a corner of the shell. If this chip is not moved to the new shell, the car will crank but will not start.

4. Transferring the Blade

The user has 2 choices for the metal blade:

5. Reassembly

Location the PCB, transponder chip, and battery into the new shell. Guarantee they sit flush in their designated slots. Line up the two halves and snap them together or replace the securing screw. Test the buttons to guarantee they have a tactile “click.”
