Yours must be standard. My 2000 was auto and would lock when you put it in gear. I whipped out the owners manual and followed the procedure to turn it off. Took me a couple of tries to get it but it worked.
I bought mine off a dealer/friend and it only had one key. One of my first trips out I got out, must've bumped the "knob" at the top of the door and shut it with it still running. Pass door still locked. That was a problem even afterwards that I kept bumping that when I get out.
Fortunately, I was only a couple miles from where I got it and he sent his kid down with a big wedge and a hook. Took 5 seconds to get in.
