Hi good day. My car is a 98 Mustang and the driver's side door doesn't stop, even if I have the insurance, it opens easily without using the key. He even pushed her inside and open. The door has always been a little down and had never given the problem. I wish someone had the time to offer me their help.

The help that can be offered is little, if it does not close, you have to take the lock to a specialist or buy one. If you are a little hand disassemble it and try to see what it has broken. .
