Car Key Won't Turn or Work

Problems like keys not turning or being stuck are likely mechanical. It could be the key or the car's ignition getting old. Or, there might be a problem with the lock. Sometimes, it's not a physical issue. It might be a programming or electrical problem instead.

A key fob with a dead battery or a wrong program could be the culprit. There might be a mechanical issue stopping the key from working with the car's start.
