Hello and Welcome! I'm Billy and i will assist you with your inquiry. Feel free to ask if any further info is needed.
do you have a second key you can try? as this is an EWS fault (immobilizer)
Customer: replied 1 year ago.
We don't have anther key
Expert:  nabilc replied 1 year ago.
Hello again,
The fault code indicates an EWS fault (tampering). So the immobilizer is preventing engine start.
The only thing left to do (as a second key is not available to try), would be connecting a scan tool, resetting the EWS, pairing with the DME (engine control module), and trying to start again.
Kindly get back to me with your results, or if further assistance is needed.
Regards,
Billy

Hello again,
you can get the spare key? is that what you're saying?
and being a shop, do you have the inpa or GT1 tester to reset the EWS and reprogram?

Hi again I have snap on Scaner only
Expert:  nabilc replied 1 year ago.
Hello,
If you cannot try using a second key (although this is not likely to work, but worth checking as it won't cost time nor money), then you need to get a BMW specialist reset and reprogram the EWS.
I'm afraid, on these models, with the immobilizer system, there is no other way.
Kindly get back to me with your findings, or if further assistance is needed.

Billy

Hello,
I'm not qualified to work on Chevy on this site (i don't have experience with them as well)... so i'm afraid, you'll need to open a new question for this, and chevy experts will sure help you with it.
You did mention a Nissan, i do work on Nissan vehicles, if you want.

Billy

Ok good I call anther technicaion and about bow what I do now
Customer: replied 1 year ago.
I mean bmw bring key or check it
Expert:  nabilc replied 1 year ago.
If you can bring the other key, that would be perfect, as this would confirm whether the key is faulty, or the EWS needs resetting.
