If a key snaps off inside the ignition, repair is a two-step procedure. Initially, the broken piece needs to be eliminated utilizing specialized extraction tools (little, thin hooks). When drawn out, a locksmith can decipher the cuts from the damaged pieces to cut a new, fresh key.
Transponder Reprogramming
When the electronic link in between the key and the car is severed, reprogramming is required. While some older vehicles enable for "on-board programming" (a series of turning the key and pushing buttons), a lot of modern-day cars and trucks require a diagnostic scanner to sync the key to the ECU.
Lock Cylinder Lubrication
While not a direct repair of the key itself, many "key issues" are really brought on by dry or stuck wafers inside the ignition cylinder. Applying a little amount of dry graphite lube can often restore smooth operation. Keep in mind: Never use oil-based lubes like WD-40 inside an ignition, as they attract dust and trigger obstructions over time.
