What to Do When the Key Won't Turn in the Lock?

[LeJaxson]

Here are the solutions for when the key won't turn in the lock: 1. The steering wheel has an ignition switch assembly, with the upper part being the lock cylinder and the lower part being the base. If the base is faulty, it must be replaced. However, if the base is poorly lubricated, you can try using dashboard wax for lubrication. 2. When the lock cylinder won't turn, the root cause is usually key wear. Over time, the key becomes slightly smaller due to wear. The solution is to have a new, slightly larger key made. 3. When the key wears down to a certain extent, inserting it won't allow the lock cylinder's pin to fully drop, causing misalignment. In this case, the lock cylinder won't turn. The solution is to have a new key made based on the original.
