What to Do When the Car Key Doesn't Work?

Solutions for when the car key doesn't work: You can use the mechanical key hidden inside the remote key to open the car door. The remote key may not work due to a dead battery in the remote key or car battery, or strong signal interference nearby. If the mechanical key doesn't open the door, it might be because the car's central locking system is in an electronic lock state. You can wait for one or two hours for the lock to be released and then try unlocking again. Parking the car for too long can also cause the door lock cylinder to jam, making it difficult to turn. In this case, you need to contact a 4S shop for repairs. In northern winters, cold weather combined with rain can cause the car door locks, handles, and door frames to freeze, making it impossible to open the door even with force. The solution is to pour warm water on the frozen parts to help the ice melt quickly.
The other day my car key suddenly stopped working, leaving me frantic as I couldn't unlock the door. Standing in the parking lot with armfuls of bags, I had to calm down first. I tried the spare key, but that didn't work either, making me think it was either signal interference or a dead battery. After pressing the key against the door handle's sensor area several times, I finally got the lock to open. When I got in and tried to start the car, it displayed 'key not detected.' Turns out, a nearby substation was emitting interference signals. After moving to the other end of the parking lot, the problem disappeared. My advice if this happens: don't panic—first try moving away from potential interference sources. If that fails, use the mechanical keyhole, usually hidden under the door handle cover. Of course, it's best to keep spare key batteries on hand—I've made it a habit to proactively replace mine every two years.
