• An RFID Transponder Chip: Communicates with the car's immobilizer to permit the engine to begin.
• Remote Locking Circuitry: Powered by a battery (in hands-free versions) to lock and unlock the doors remotely.
• An Emergency Metal Blade: Hidden inside the plastic case to by hand open the motorist's door if the battery passes away.
• Microswitches: Internal buttons that sign up when the user presses the lock, unlock, or boot buttons.

Typical Failure Points

Over years of use-- being rested on in back pockets, dropped on pavement, or exposed to moisture-- the internal parts take a beating.

A Step-by-Step Guide to DIY Laguna Cardkey Repair

Disclaimer: Attempting to repair a keycard yourself carries the danger of harming the delicate internal components beyond repair. Continue with care.

• Essential Warning: Be incredibly careful near the leading edge of the card where the internal antenna coil is located. Slipping with a knife can sever the fine copper wire, rendering the card completely useless.

Step 2: Inspecting the Circuit Board

Once the plastic shell is split open, carefully slide out the internal printed circuit board (PCB). Utilize a magnifying glass or a smart device video camera zoomed in to check the board. Look for:

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

Action 3: Resoldering Faulty Connections

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

Step 4: Testing and Reassembly

• Before gluing the plastic housing back together, take the circuit board out to the car and test it in the card reader.
• If the car acknowledges the card and starts the engine, the repair was effective.
• Use a percentage of plastic-safe superglue or epoxy along the external edges to re-seal the housing. Avoid utilizing excessive glue, as it can leak inside and foul the buttons.
