jdg0928 Posted November 18, 2022 Report Share Posted November 18, 2022 (edited) The dealer checked the battery at my request, and that was the problem. They dropped in a new one -- covered under warranty! -- and now Intelligent Access works on all four doors.

crazeyone Posted January 16, 2023 Report Share Posted January 16, 2023 I have been reading the responses and tried a new battery with no luck. I read a little deeper in some of the Ford pages and found this and it worked. Take your key fob and get within three feet of the door. Press and hold the lock and unluck button on the FOB for 3 to 5 seconds and you will hear the click and I saw the lights on the mirrors flash and mine went back to working. 1 Quote Link to comment Share on other sites More sharing options...
jimk1 Posted December 31, 2024 Report Share Posted December 31, 2024 Found numerous threads reporting that Intelligent Access (IA) stopped working except on Driver's door only. Lots of commentary about replacing the "12 volt battery", implying the car's main lead acid battery. Turns out there is a second "12 volt battery", according to Ford Pass Technical Support - this is the battery causing the issue. More below, hope this helps others. 2019 Edge ST original owner: Intelligent Access (IA) worked on all 4 doors until about 6 months ago - now works only on Driver's door. Called Ford Pass Tech Support, spoke with a technician. She reported that the vehicle has a SECOND 12 volt battery, which is hidden in the dash somewhere and is a backup battery for the cellular modem. This battery is apparently used for IA, and is rechargeable (she didn't know if it was lithium ion or some other chemistry). She remotely read the charge level on this second battery, it was at 36%. Normally this battery is at 85% or higher. If the system measures <75%, the Intelligent Access feature will dumb down to just the driver's door to save battery power. In her training, the battery was also named "12 volt battery", which she found dumb, and confusing to both the techs and customers. I asked her if the battery is serviceable by customers, she said no due to its (highly) inconvenient location. She also alluded to a potential issue with a connection to that battery, that might be the root cause of the battery not charging properly. I've contacted my local Ford dealer service tech - car goes in next week to check this out. Service tech also made an offhand comment about confirming what the real issue is, regarding connection to that battery. Hmmm. It helped greatly that the Ford Pass tech diagnosed this first; I got the impression the service tech was already familiar with this problem.

redden18 Posted 5 hours ago Report Share Posted 5 hours ago IMO, it is a battery. I have it happening every time when it is cold outside, like, below -15C for several days in a row. I don't think there is a reason to change it but to charge it before the cold time. Well, unless the battery is really old like 4-5 years.
