Lock Cylinder Lubrication
While not a direct repair of the key itself, numerous "key concerns" are actually caused by dry or stuck wafers inside the ignition cylinder. Using a percentage of dry graphite lubricant can frequently restore smooth operation. Note: Never use oil-based lubes like WD-40 inside an ignition, as they draw in dust and cause clogs with time.
