• An RFID Transponder Chip: Communicates with the car's immobilizer to enable the engine to begin.
• Remote Locking Circuitry: Powered by a battery (in hands-free versions) to lock and unlock the doors from another location.
• An Emergency Metal Blade: Hidden inside the plastic casing to by hand open the driver's door if the battery dies.
• Microswitches: Internal buttons that register when the user presses the lock, unlock, or boot buttons.

Typical Failure Points

Over years of usage-- being rested on in back pockets, dropped on pavement, or exposed to moisture-- the internal elements take a pounding.

2. Professional Repair Services

• Pros: Cost-effective (generally a portion of car dealership rates), fast turnaround, maintains the original programs so no car re-coding is required.
• Cons: Requires discovering a reliable expert who manages automotive electronic devices.

3. DIY Repair

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

Disclaimer: Attempting to repair a keycard yourself carries the risk of damaging the fragile internal components beyond repair. Continue with caution.

• Essential Warning: Be very careful near the leading 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 useless.

Action 2: Inspecting the Circuit Board

As soon as the plastic shell is divided open, carefully move out the internal printed circuit board (PCB). Use a magnifying glass or a mobile phone video camera focused to inspect the board. Try to find:

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

Action 3: Resoldering Faulty Connections

• Heat up a fine-tip soldering iron.
• Use a small amount of fresh electronic solder flux to the suspect joints.
• Carefully reflow the solder on the weak connections. The goal is to remelt the existing solder to bridge any microscopic fractures 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 recognizes the card and starts the engine, the repair was effective.
• Use a percentage of plastic-safe superglue or epoxy along the outer edges to re-seal the case. Prevent using excessive glue, as it can seep inside and nasty the buttons.
