To be clear, this is the cylinder ignition lock we are talking about, not the ignition starter switch. If the tumblers are damaged or 'bad', the key may be able to be removed fromt the ignition lock while the car is running. Also, the key may simply not go into the ignition lock anymore. On most cars the cylinder ignition lock is a separate item and can be replaced for a moderate price. However, this is not something for a novice to work on since this is just one of many interconnected parts. Messing with a ignition system may make your vehicle unable to simply start again.
