The Process:
Inspect the board under a magnifying glass for split solder joints.Use a fine-tip soldering iron to re-attach the loose component.Guarantee no "solder bridges" (additional solder touching two courses) are developed, as this will cause a short circuit.Understanding Reprogramming
Sometimes the hardware is completely functional, however the remote has "forgotten" its connection to the car. This frequently takes place after a battery has been dead for a prolonged period or if external radio frequency interference has actually caused a desynchronization.
