When a key fails to turn, follow these steps in order to isolate and possibly repair the issue:
1. Examine the Steering Wheel Lock
Sometimes the problem isn't the key at all. The majority of cars have a steering lock that activates if the wheel is moved while the engine is off.

If the internal wafers are stuck, a light vibration can sometimes release them.
Action: Insert the key and, using a little mallet or the deal with of a screwdriver, gently tap the head of the key while attempting to turn it. Warning: Do not use excessive force, as this can break the transponder chip.When to Replace the Ignition Cylinder
