Yea, SO I thought it was a problem with just the remote, which wont unlock the driver side door, but it will unlock all other doors, but when I get in the driver seat, and hit the unlock button in the car, it still wont unlock the door, I have to manually push the lock down, and use my key to open my driver side door. SO what could be the problem? I am guessing I turned on the security door feature, by accidentally touching the remote buttons incorrectly or something? Please help.

 

its a failed door lock actuator, its not electrical because if it was, the other doors would instantly relock.
