Ford excursion door locks not working

ANYONE HAVE ANY SUGGESTIONS OR ANSWERS??? PROBLEMS WITH DOOR LOCKS ON 2002 FORD EXCURSION....My door locks were working fine up until a few month ago when I added a TS chip to my truck...I first noticed the security light stayed on for about 5 minutes of driving...I contacted TS about this problem and they advised that all Excursions with the factory security would do this with the chip...Then after about two months from time to time the locks would lock and unlock while driving down the road..The next problem was my key fob would not lock or unlock the doors from time to time...Now my door ajar light stays lite most of the time while driving and after I cut the truck off the doors will not auto lock and the radio stays on..The radio will eventually cut off in 5-10 min and the doors will lock sometimes..The only info I find on line in regard to door lock problems is with the actuators...Dont belive this is the problem because when locks decide to work the actuators are hitting hard. Also read on another site about cleaning all the door and hatch contacts with electical contact cleaner..Well that was like throwing $6.00 in the wind.

I have an '02 7.3 F250 with the same problem. It began well after I installed an Edge Juice w/ Attitude. I now have a TS chip and the same problem still. I have tried the door slamming and the spray oil in the doors that shut the light off for a couple of days however it is back on now. Is anyone else having these issues?

For the faster solution, try to contact a locksmith service near you.

With all the issues you are having with the various electrical problems I would probably look into your gem module first, especially if your windshield is leaking or has in the past.

I am having the same issue , i will check as you have said above and then i will hire a mechanic or locksmith for repair.

Now my door ajar light stays lite most of the time while driving

Sounds like the drivers master door switch is having issues
There is a contact wire on the latch mechanism, when the drivers door is shut the wire is grounded out. If the switch or mechanism has issues the truck will think the door is open all the time.
I would remove the drivers door panel and have a look see

You can lubricate it from outside, sometimes that helps free a sticky switch, sometimes the mechanism needs to be replaced.

Can also of course be a different door, it is not always the drivers door, but that is the one that gets used the most and has the most failures.
Not sure how many switches there are on an Excursion

Back from the dead thread.

The OPs problem does sound like the GEM module. Almost every symptom listed has zero to do with a chip.

There must be the problem in the door wiring , they must call the mechanic and replace it with new one. I also have some issues with it and i have called locksmith, but in the end i have to call upon mechanic and done replacement of inner wiring to fix the problem.
