23 F350 Proximity unlock issue
 

Anyone have an issue with their proximity lock/unlock feature that is built into the door handles on the front doors? Mine was working fine and now the lock button does not work and if I put my hand behind the door handle it will not unlock either. Truck was bought new in Dec 23 and now only has less than 2000 miles on it.

Did this occur after getting them wet? I had the same issue on a new Charger I purchased. It would happen after heavy rain or when they got wet. The dealer replaced both with a updated part number and never had the issue again.

Do mirrors and running boards extend? Any lights come on?
What trim level do you have? Mine has settings in the screen menus for "Approach detection" or some such.

Left side under handle unlocks, right underside locks.

Lariat Ultimate. No lights. Steps and mirrors normal

been raining a little lately is all. Nothing too major.

mine have failed to work 1 or 2 times. start the truck and they work again 🤷🏻‍♂️

The steps work when I walk up to the truck. It’s just the lock and unlock with the handles that’s not working. Need a dealer visit I guess

Same issue on my July 2023. Dealer could not find an issue. Next day it stopped again and sent them a video. Their only suggestion was to bring it in when it was acting up.

Good morning! Feel free to send us a DM with your vehicle's VIN and mileage. I’d like to see what I can do to assist with having your lock/unlock issues addressed.

TL/DR: have you tried charging the battery(ies)?

Something I found after getting my truck was that it needed to have a trickle charger on it for a bit after I first got it. I was continuously getting low battery messages in the app, and noticed the approach and door handle sensors would not work. I have the dual AGM batteries mind you, and this was still an issue. It seems there are so many electronic systems that are constantly leeching from the electrical system. Unless you're driving the truck daily, it is surprising how quickly the voltage drops. Even with auto updates and such turned off, there clearly is quite a bit of background functions taking place when parked (such as GPS and all of the data constantly being sent to Ford for general vehicle status).

Just the other day, after not driving it for a couple weeks I noticed that neither the approach nor the door handle unlock features worked. Truck cranked right up and all, and after driving 20 minutes to my destination, the approach and door handle unlocking features both worked. It's been on trickle charger for 1.5 days currently and still showing not fully charged.

Interesting, the low battery messages in the app never showed up again in the past 6+ months, even though the symptoms of low battery voltage have been present.

Dual AGM batteries in mine as well. I have a battery meter on my amplifier. It constantly shows low 14s and high 13s - low 14s when the stereo is playing. Also just got back from a 400 mile round trip so plenty of driving and charging. No luck I have been going door to door and trying all touches, angles, pokes, and prayers haha. The keypad still works. The power steps sense me walking up to the truck and deploy and the lights also come on when I walk up to it. Just the door handles it seems are not working. It just happened out of the blue and it’s been probably a week or better now and still not working.

Ah, ok, I was hoping low battery voltage could be the culprit and a relatively easy fix. Sorry to hear like it's something else. Hopefully it'll turn out to be something else relatively easy to fix.

Yeah me too. Here is the digital readout from the amplifier.

Same exact issue I am having.
