    If the key does not work on the door he unlocked for you I suspect linkage to door latch could have gotten bent or dislodged. I assume the wreaker driver used a tool called a slim jim to unlock the door?

    Tow truck driver pride the door open with a bag that he had to pump air into, then with this rod he hit the unlock switch. Can there be like an anti-theft system when the alarm went off? That maybe froze the door-locks, I took door panel of an linages look intack and not bent. Thanks for your help.

    Ahh...that's the problem your car has a "Content Theft Deterrant" system and it has armed itself thinking it has been broken into. And here is the information you need to disarm that system that I have cut and pasted from manual: Read and follow carefully...it should do the trick.

    IMPORTANT: Using the power door unlock switch or manually unlocking the doors does not disable the CTD arm mode. Also, disconnecting the battery or pulling fuses does not disable the arm mode, since the BCM stores the CTD mode status in memory.

    •To disarm the CTD system in standby mode (theft LED flashing fast and door(s) open), perform one of the following:
    •Press either power door unlock switch.
    •Use the key to unlock either front door.
    •Press the UNLOCK button on the keyless entry transmitter.
    •Insert a valid key into the ignition and switch to the ON position.
    •To disarm the CTD system in the armed mode:
    •Use the key to unlock the either front door.
    •Press the UNLOCK button on the keyless entry transmitter.
    •Insert a valid key into the ignition and switch to the ON position
    •To disarm the CTD system when activated (alarming mode).
    •Use the key to unlock either front door.
    •Press the UNLOCK button on the keyless entry transmitter.
    •Insert a valid key into the ignition and switch to the ON position.

    Wiring may have been damaged using the "tool"
