Why can't the car turn off and the engine keeps running even after removing the key?

If the car can't turn off and the engine keeps running even after removing the key, it might be because the automatic transmission model is not in the P (Park) position. For manual transmission models, you should check the lock mechanism as it might be stuck. Additional details: 1. Other possibilities: Check if the car is out of fuel, as naturally it won't start without fuel. If the issue is due to lack of fuel, simply refueling should solve the problem. 2. Precautions: Also, verify if the battery is dead. Prolonged use of electrical devices can drain the battery, preventing the car from starting. This situation is more common in older cars that have been left unused for extended periods.
I think the car won't shut off, even after removing the key. This could be a problem with the ignition system. I had a car like this before, and after struggling for a while, I found that the contacts of the ignition switch were stuck and didn't completely disconnect, so the engine kept running. It could also be a faulty relay—this little thing controls the current, and if it fails, the circuit won't cut off. If there's a short circuit or a bug in the control module, the computer commands fail, and the car becomes as stubborn as an ox. More seriously, excessive voltage or an abnormal alternator can cause system chaos. This is quite dangerous—driving without being able to stop can easily lead to loss of control. When I encountered it, I immediately shifted to neutral, pulled the handbrake, and hurried to a professional repair shop. Usually, it's important to pay attention to regular circuit inspections to prevent minor issues from turning into major troubles.
I experienced this once - the engine kept running after pulling out the key, which really startled me. After some thought, it might be due to worn key locks or sockets failing to trigger the shutdown signal. Or it could be a stuck relay - small but crucial, if jammed it won't cut the current. A short circuit could also keep the system powered, like tangled power cables. If the engine control module fails, it might ignore shutdown commands. Important reminder: don't push your luck in such situations. Stop immediately, turn off other electronics, and first check relevant components in the fuse box. If unresolved, push to roadside and call a tow truck. During maintenance, remember to clean lock holes and switches to prevent aging - saves money and ensures safety.
