You have a internal issue with the NATS system module .

You are learning the key but as soon as you switch off its loosing the code .

This is due to a internal module problem with the back up power ,check that the connection is good remove and clean with contact cleaner ,still having issue then have a new module installed and programmed .

Need further assistance with this issue then please get back to me with the reply box below .
After rating there is no further cost for any other question relating this issue .
Kind regards Greg

OK! But who is this module with power problems? BCM, NATS antena,ECU or another?
Can you tell me, what is the function of this marked on the attached picture? Is it only micro switch who give information for key location? Is it available, problem to be there ?

Sorry, I had not read the first sentence. The problem is in NATS module. Is it NATS system module, different of BCM? If it different module - where is location of it?

Hi .

The photo with the ring is the Key antenna .

On the smart entrance module you have a Ignition power which is there when ignition is switched on and a

battery power which is there at all times . this wire could be shorted or the module is bad .

Attached is a typical NATS system .

Thanks for the answer, but this is not my question. On the picture with green is noted key antenna - right? But with red I was noted black plastic, different from antenna ring, whit two wires. It's maybe 20 mm from key ring(antenna).
When I disconnect wires, the Ecu do not write any additional errors. I think that it is a micro switch, and it "tell" to NATS, key is in to the ignition barrel. Is it a correct?
