error with remote door openings and no key detected

[FelipeN]

Hello good morning,

I have a problem with a Shelby GT350 from 2017, the problem is that the opening and closing from the remote control does not work, nor does the start inside the car work, error the key is not detected. In order to start the car I just have to insert the key into the slot and it works.
I already ruled out that they were the batteries for the controls, and I also discarded the remote itself with 2 other new controls.

The programming with forscan is completed but it does not perform any function of the remote control and the only codes I have in the body control module are:

U2101:00-0A
U2100:00-8A

The overhead lights flash constantly.
I was taking measurements of the different antennas that it has in the lower center part, under the trunk, and both door handles, marking around 1.6 ohms. and the only thing I find out of
It is normal that the RTM module's part number is not the same as the one in the catalog.

The car arrived with these problems, already going through many workshops, and they changed many components that I believe are not compatible. according to my opinion.

Someone who can guide me if the problem is due to the Body Control module with the codes it has or it could be a problem with the different operating modules of the opening and closing system.

I would make a backup of the ASBUILT configration on the BdyCM module. Then I would fetch and restore the factory configuration from Ford:

https://www.motorcraftservice.com/AsBuilt (enter the VIN)

Also -- I don't think it's the cause -- but if you use a key that is the wrong frequency, it will behave the same way. Ensure that you are using the correct key type for the car. It should be a 4-button with a cobra logo on the back. For example, the 5-button with remote-start and the snake logo (KR3V-15K601-AC) is the wrong frequency for my 2018 GT350.

The overhead lights flash constantly.

If the dome light is flashing this means there is a issue with the wiring/modules in the vehicle. It is probably a symptom of U2101:00-0A.

Error code still happens if you do a module reset in Forscan for the BdyCM?

I think you probably have an incorrect AsBUILT configuration for the module you need to sort out.
