Ford Kuga keyless 2019 all key lost

[bendix2]

I didn't replace BCM, I replaced RFA module.
Last characters not same (F1CT-19G481-AL -> F1CT-19G481-AE), but my informator said it's only software version, so it's good instead of that.

Last days I needed to work other cars, but this Kuga still doesn't start, can't learn key.

I tested antenna's, when I disconnect REAR or FRONT antenna, then I get fault code in rfa (rear fault code, and front fault code. and still always center antenna fault code). So maybe center antenna is the problem, because it's ALWAYS fault code. (When I clear and I try to push start button)
BUT I check wires, good! I cut wires from rfa pinout to take a test, and I try with new wires. I took antenna from the car and I connect NEW center antenna with NEW wires outside car (because I want to test 100% this antenna give signal.) And yes, outside car, I check antenna signal, it's work, antenna give signal. New wires, new antenna, give signal, but "ignition center antenna - B10C8" always fault code.

I don't know.. maybe this rfa also fault, but old rfa also have center antenna fault, so I think it's impossible.
Or BCM fault.. I tried with steering lock emulator (maybe steering lock fault), not. But now I order new steering lock (Sometimes dash show steering malfunction, but I can't communicate without make bridge ignition relay, but if I make I can communicate and no fault code.) But have little mechanic problem. So tomorrow I try with new steering lock.

After that I don't know.. new bcm?
I really don't understand, everything good.

Yes the BCM is faulty I had this on Ecosport

Really? But not fault code in BCM, just I think maybe controlling something wrong.
What happened your ecosport?

The customer bought the car from auction with heavy front crash without keys

I tried to program keys but the car not accept the keys

I replaced the BCM and the car accepted the keys
