2006 Mariner - Rear Door Auto-unlock? - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

I have a 2006 Mercury Mariner and the autolock feature is on, so when I shift into gear (drive, reverse) the doors automatically lock. When I shift into park, the front driver and passenger doors automatically unlock, but the back doors and liftgate remain locked.

I have scoured my manual and can't find anything. I see how to enable/disable the entire autolock feature (all doors), but it doesn't specifically address the rear doors. I have only owned my Mariner for about a month so I don't know if this is normal or if the locking system is malfunctioning.

Any insight?

Check to see if the child safety lock switch is engaged in the rear doors. I can't see the rear hatch having one, but it doesn't hurt to look.

At least you have the auto unlock. It's force of habit that I press the unlock button on the door once I park my Dodge Durango, lol.

It's a normal and supremely aggravating behaviour. Where did you find instructions on disabling the whole autolock thing? We curse that feature every time we go shopping and get home to unload...

n'mind. Think I found it. If it works, I'll link it in.

Ah, yes... "supremely aggravating" describes that feature so well. Thanks for posting; even though I am not happy to hear that it's normal, I am happy to know that my vehicle isn't malfunctioning. The procedure to disable the entire autolock system is in the manual. If you don't have the manual and need the procedure, let me know and I will post it here. I'm going to disable the whole damn thing tonight.

Thanks to the manual, I've already disabled the annoying seatbelt alarm and reprogrammed the key fobs to unlock all doors with one button push. I must say that the manual has been very helpful. There may be some really stupid features on the vehicle but at least they give you directions to can them.
