Transponder Reprogramming

When the electronic link in between the key and the car is severed, reprogramming is required. While some older vehicles permit for "on-board shows" (a series of turning the key and pressing buttons), the majority of contemporary cars need a diagnostic scanner to sync the key to the ECU.

Lock Cylinder Lubrication

While not a direct repair of the key itself, lots of "key problems" are actually brought on by dry or stuck wafers inside the ignition cylinder. Using a percentage of dry graphite lube can often bring back smooth operation.
