Lock Cylinder Lubrication
While not a direct repair of the key itself, lots of "key concerns" are in fact triggered by dry or stuck wafers inside the ignition cylinder. Using a small amount of dry graphite lube can often restore smooth operation. Note: Never utilize oil-based lubes like WD-40 inside an ignition, as they draw in dust and cause blockages over time.
