Auto door locks?

when I first started driving my TC back in 2004 I can remember the doors locking when I went from reverse to 1st.  was this an option or did I have something crossed?  the car hasnt done this for a long time so I dont know if it was supposed to be doing it or not and if it was I'd like to get it figured out so it works again.

most newer cars lock the doors when you shift through reverse to help keep the doors closed in case of an accident. its also safer because it helps prevent car theft like in places where people will try to steal your car while you parked at a red light(i dont know if this was intended by the manufacturer or not).

i dont know if they did this as early as our cars or not, i have an alarm system that wasnt wired up right my the previous owner and my locks will lock at random.

The auto lock feature is part of the keyless entry system. Sometimes when you disconnect the battery the keyless entry system will lose the ability to remember the auto lock function. That happened to me a few times with my old '88 Sport.

Grutinator is correct...when the car is running, there is an object in the driver's seat (preferably an ass LOL) and the shifter is put through Reverse, the doors should automatically lock. Conversely, after driving when you put the car through Reverse into Park, they should unlock.

If your car has lost the ability to do this, enter your code into the keypad, and within 5 seconds, press the 7/8 key and HOLD it, then press 3/4 (while still holding the 7/8 key), and then release both. That *should* activate it. The same sequence also deactivates it.

There is a wiring harness that goes to your driver's seat that, if disconnected, will make the auto lock feature not work. It's a 2-wire harness; I want to say the wiring colors are black and white/black. You can check that connector and wiring if you still can't get it to work.

so how do you know without actually running through the gears if the function is reactivated?

Why not just run it through the gears?

I'll try it on my way to work this morning, was wondering if it would lock the doors or flash the interior lights or give some kind of indication that it was reactivated.

No flashing lights, sorry. It either works or it doesn't. I remember having to input that sequence a few times...there is no feedback. As soon as you start the car and put it in gear, you'll know. ;)

yeh my 87 sport coupe has this.  usually when i put it in reverse, back it out etc and then put it in od/d its automatically locks.  on the other side of the coin though, i have to unlock my doors instead of them unlocking automatically.  really all i believe you have to do to see if it works is put it in reverse and then put it into gear (d/od/1 for AOD transmissions) but for a TC with the 5spd im not 100% how to check.  i'd imagine you could check by putting it in reverse, backing up a few feet and then go into first and head out on your way it should lock.

I used this same procedure to turn on my Auto lock in my Mountaineer..  But it honks when it turns on and off :hick:

Never had the TC together long enough to actually play with this feature.

Mine lock, but they have NEVER unlocked when I put it in park.  I never even knew it was supposed to do that!

I don't think I've ever seen a Ford unlock the doors.  Every Ford vehicle I've been in unlocks the door when you open it via the inside door handle.  The vehicle locks the doors but does not unlock them.  Now GM unlocks the door, but thats because the door handle does not unlock the door with a simple tug.
