Transponder Reprogramming
When the electronic link between the key and the Car Key Remote Repair is severed, reprogramming is needed. While some older automobiles allow for "on-board programs" (a series of turning the key and pressing buttons), most modern-day automobiles require a diagnostic scanner to sync the key to the ECU.
Lock Cylinder Lubrication
While not a direct repair of the key itself, numerous "key problems" are in fact triggered by dry or stuck wafers inside the ignition cylinder. Applying a little quantity of dry graphite lubricant can typically restore smooth operation. Note: Never use oil-based lubes like WD-40 inside an ignition, as they draw in dust and trigger obstructions over time.
