Autel IM608 2020 Nissan Sentra Add Key Not Working Solution

Here comes the problem:

I tried to do program the key on 2020 Sentra and IM608 killed that car.  I was trying to add a key but something seems to have gone wrong. I plug the connector to the gateway module and to my Autel MaxiIM IM608 (in picture) then went to manual selection, then add a key. For some reason it is now locked up and the existing key will not work. Any guidance would be appreciated.

Pulled these codes

Here is the solution with the help of Autel tech support.


He was able to restore the bcm and ecm by going to HFM restoration then pulled the pin code and added the key WITHOUT buying an ecu or bcm.
Selected by System where it ask me for the vin and manufacturing date.

Then selected the option that says hmf restoration and it brought the car back to life and gave my the code.

Here’s the pics to prove it.

If not working and your car is under the warranty. Called the Dealer and the car doesn’t start at all. The Towing company will take the car to the dealer, they will replace the Smart Key module because it is dead.

Dealer is not the only option.  You can get bcm or ecm replaced and have it reprogrammed by Nissan consult 3+.


Anyway, stay away from Sentra. It is dangerous to deal with these Nissan. You may have bricked the BCM.
