I just bought this truck from my friend's dad, who is a mechanic with his own shop. I get cars from him all the time. I have tried twice to get my car after work (and after shop is closed) by telling them to leave the key in it and door unlocked. Both times I went to get it, the doors were locked! We can't understand how they are locking, unless they are timed or there's an electrical problem that causes this. I tried to Google for this problem, but didn't turn up much without having to really dig into some sites. I hope someone has some insight into this problem. Thanks.

Yes, it does have an aftermarket keyless entry/remote starter FOB (key FOB? I think that's what it's called). Do you think this may have something to do with it? Hmmm. The key (and remote) has been in close proximity to the truck (in it actually), so maybe after so long, the remote locks the doors. I guess I won't know that for sure until I get the keys and let the truck set over night or something (unlocked), where the key FOB isn't anywhere near it. If the doors become locked, them it must be something else. Thanks for the quick reply. Another other info is greatly appreciated.
