Q: Key not working

asked by on

My key no longer turns in my ignition.

Hi there. This problem is caused by a lack of mobility in your ignition cylinder. The bumps on your key depress a series of channels in the cylinder in the correct combination in order for it to release it’s locking mechanism. If one of these channels is not depressed the cylinder will not allow your to turn the key. A replacement of the ignition cylinder should solve this problem. If you would like to have your key issue diagnosed, have a certified mechanic come and inspect your ignition first.
