Hello I am new to the F-150 Forums I wanted to come on here to see if anyone knows how to fix a problem I have or give some advice. I was messing around with FORSCAN enabling global windows on my 2018 F-150 XLT because I thought it would be cool. I was also enabling Bambi mode, 5 ticks for the blinker instead of 3 ticks. While I was doing that I had clicked the KeyFob during one of those and then the KeyFob had just stopped working. The truck has 2 keyfobs and they both do the same thing they don't lock or unlock it. After that the truck still recognize (It wouldn't unlock or lock it though) one key because when I would get close and hit the unlock or lock button it would say low battery replace battery. It is a flip key and it still starts the truck but I just does not unlock or lock the truck anymore if anyone could help or give advice it would be greatly appreciated.

 

Did you check and replace the key fob battery? The battery in the remote is used for the remote functions, but it is not used to start the truck with the physical key. In other words, a dead battery in the remote will not allow the unlock/locking buttons to work on the remote but it will still allow the truck to start with the physical key as the security part is handled differently.

 

The thing is me and my dad looked at it and the key fob battery’s were change and still doesn’t unlock/lock the truck

 

Return it to stock and see if the problem corrects itself.

 

Welcome to the forum.

Agreed, return it to stock and see if it works. Recommend doing only one mod at a time, making sure you have a charger/maintaner connected to the truck during FORSCAN sessions, and always backing up any modules before you modify them.
