The key in my car goes in, but will not turn.
There could be one of several possibilities: A worn key is the first suspect. If another key exists, it can be tried. If not, another can be cut from code, but this is expensive. The other possibilities are an ignition lock cylinder, or housing, or both. Replacing the ignition lock cylinder, and/or the housing, requires removing the steering column trim, and the housing is attached with sheer bolts that will need to be driven out with a punch. You may want to enlist the help of a mechanic, such as one from YourMechanic, who will have the tools and expertise to inspect your key not turning issue, and suggest the best path to repair for your ignition lock system.
