• Important Warning: Be exceptionally cautious near the top edge of the card where the internal antenna coil is situated. Slipping with a knife can sever the great copper wire, rendering the card totally ineffective.

Step 2: Inspecting the Circuit Board

As soon as the plastic shell is divided open, gently move out the internal printed circuit board (PCB). Utilize a magnifying glass or a mobile phone cam focused to examine the board. Search for:

• Micro-fractures in the solder joints, particularly around the IC chip and the internal battery holder.
• Loose components that wobble when gently nudged.

Action 3: Resoldering Faulty Connections

• Heat up a fine-tip soldering iron.
• Apply a tiny quantity of fresh electronic solder flux to the suspect joints.
• Carefully reflow the solder on the weak connections. The objective is to remelt the existing solder to bridge any tiny fractures that are obstructing electrical continuity.

Step 4: Testing and Reassembly

• Before gluing the plastic case back together, take the circuit board out to the car and test it in the card reader.
• If the car recognizes the card and starts the engine, the repair achieved success.

• Change Batteries Promptly: If the remote functions begin to lag, alter the CR2016 or CR2032 battery (depending upon the design) before it leaks and wears away the battery terminals.
• Utilize a Protective Silicone Sleeve: Inexpensive silicone covers include a layer of shock absorption, safeguarding the tough plastic shell from cracking during unexpected drops.
