Unlocking & Lights Come on Randomly

[ExpeditionTrouble]

I have a 2015 Platinum EL Expedition w/ 150k miles and recently have found the lights on intermittently during the day & night as well as the doors being unlocked several times. Not able to pin down the cause but have checked battery voltage after driving vs next morning, load tested battery and checked for codes but have not had any luck finding the culprit. Both key fobs work and have new batteries and are not subject to be activated by accident.

Anyone have a similar issues or have any advice for trouble shooting to narrow down the culprit?

could be your key fobs wearing out so the buttons get loose and cause the vehicle to unlock/lock multiple times throughout the day. Happens to remote fobs for all brands if used enough times.

Can try popping a fob open and see if you can remove any slack on the fob contacts. Otherwise it may be time for new fob(s).

I am currently having the exact same issue with my 2015 EL Limited. Constantly hearing the horn go off like someone is repeatedly locking the doors, meanwhile the fob is hanging on the key rack by the door. I just ordered two new fobs hoping that will solve the issue.

Hi, I’ve got a ‘16 Platinum with the same issue. Did the new fobs fix the issue? Thanks!

I had my 17 unlocking by itself, then without warning the unlock button stopped working. Had to enter the vehicle using the physical key in the FOB. Replaced the bad key and all is well.
