1. Difficulty turning the key in the ignition: This is one of the most common signs of a faulty ignition switch or key cylinder. If you're having to force the key into the ignition, or it's getting stuck, it's likely time for a replacement.
2. Key doesn't turn at all: If you can't turn the key in the ignition at all, it's likely that the key cylinder is damaged or worn out.
3. Ignition switch doesn't spring back: After you start your vehicle, the ignition switch should spring back to its original position. If it does not, it could mean that the switch is faulty.
4. Vehicle won't start: If your vehicle won't start at all, it's possible that the ignition switch or key cylinder is to blame.
If you're experiencing any of these symptoms, it's important to have your vehicle checked by a qualified mechanic as soon as possible. A faulty ignition switch or key cylinder can make it difficult or impossible to start your vehicle, which could be a dangerous situation.
