You have to use a key and lock then unlock either of the front doors it does not have to be the driver side. I suppose if you don't have a working key or lock you could take the door panel off and remove the wire and sit inside and manually switch the wires, I don't know if its a make or break to unlock, I'd have to hit the books. And of course the battery is connected when doing the lock and unlock deal.

If you have an owners manual it explains it.
