When the card is placed into the dash slot (or brought inside the cabin for hands-free designs), the car discharges an electromagnetic field that powers the chip, confirming the car's security code to allow the engine to begin.

Tools Needed: Soldering iron, microscopic magnifying glass or jeweler's loupe, fresh solder, and flux.Action 1: Open the key card housing carefully.Action 2: Inspect the circuit board under a magnifying glass. Look closely at the points where the battery holder connects to the board, in addition to the copper wire coil.Step 3: Apply a small amount of fresh solder to the broken joints using a fine-tipped soldering iron. Reflowing the solder re-establishes the electrical connection.Step 4: Reassemble the card once the board has cooled entirely.Repair 3: Replacing a Damaged Shell Casing
