Help! I was disturbed when I locked the car today, and the door couldn't be opened.

Hello, this usual trick is that they usually take a jammer to interfere with your remote control to lock the car. Obviously, they pressed the lock button, but due to interference, the car was actually unlocked. But as you said, if the remote control key can't be opened, it is recommended to open it with a mechanical key. If it still can't be opened and locked, it may be that the door lock is broken and needs to be checked in time.
