A transponder chip: Communicates with the car's immobilizer to permit the engine to begin.A remote locking radio frequency (RF) circuit: Powered by a little battery, responsible for locking and opening the doors remotely.An induction coil: Used in hands-free designs to charge the internal rechargeable battery or interact via distance sensing units.
With time, bending the card in pockets, dropping it on tough surface areas, or natural battery degradation causes 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 tiny amount of fresh flux to the suspect joints. Touch the hot soldering iron suggestion to the joint till the solder melts, reconnecting the element securely to the board. Pro Tip: Pay unique 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, leave to your Laguna, place the card into the dash slot, and verify that the "Card Not Detected" message is gone and the car begins smoothly.Reassemble: Apply a thin bead of plastic-safe very 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
If you own a higher-trim Laguna with hands-free entry and drive abilities, your card consists of a rechargeable battery or additional proximity sensing units.
For rechargeable cards (Laguna II Phase 2): These cards charge while inserted in the dashboard slot. If you only do short journeys, the internal battery may never completely charge. Attempt taking a 30-minute drive to permit the car to inductively charge the fob.Proximity sensors: If the car doesn't open when you pull the door deal with, but begins fine when the card remains in the dash, the interior low-frequency antennas or the card's matching receiver may be defective.
