Q: Car key won't turn

Hi. There are only a few reasons why your key will not turn. Most of the time it is because the steering wheel is locked in one direction putting pressure on the key lock cylinder, or the cylinder is not functioning correctly. Try a spare key if you have one. Also try pulling on the steering wheel in both directions to see if the key will turn. If it still will not function, put some WD-40 on the key and push it in and out of the key cylinder. If there is no success, a mechanic would typically replace the key lock cylinder. I would recommend the help of a certified mechanic, like one from YourMechanic, to service your vehicle.
