With time, flexing the card in pockets, dropping it on hard surface areas, or natural battery deterioration triggers internal solder joints to crack and batteries to fail.

Put it under a magnifying glass. Look carefully at the soldered connections-- particularly around the big copper coil antenna and the microchips. Search for dull gray rings, fractures, or loose parts.Reflow the Solder: Plug in your soldering iron. Apply a small quantity of fresh flux to the suspect joints. Touch the hot soldering iron tip to the joint till the solder melts, reconnecting the element firmly to the board. Pro Tip: Pay special attention to the terminals of the battery holder and the antenna coil, as these bear the most physical tension.Test Before Gluing: Before sealing the card back up, walk out to your Laguna, insert the card into the dash slot, and validate that the "Card Not Detected" message is gone and the car starts efficiently.Reassemble: Apply a thin bead of plastic-safe super glue around the outer border of the card real estate, secure the halves together, and wipe away any excess glue.Action 3: Troubleshooting Hands-Free (Keyless Go) Failures
