1994 Blazer auto locking doors?

[Stewy]

When I start my Blazer, after a few seconds the doors lock. It doesn't matter if it's in gear or not. Is this a factory thing or did a PO have something done for this to happen?

Auto locks on a 94? I doubt that was an option my 98 doesnt even have that option. does it have a aftermarket alarm system?

Mine does it aswell. I've got a viper so that's why. No they don't come with it Oem I can turn mine off at will and it won't auto lock

Hmm. I really don't know. I don't have a key for, just the door key and ignition key. What would I look for to see if there was an aftermarket alarm or something else?
