2008 infinity g37 base coupe

pretty stumped on this one, car left me stranded because I got out to pick something up and turned car off, returned 30 seconds later and could turn the car to on or acc mode, can’t lock and unlock car, or literally anything.

ive replaced the positive terminal fuse and assembly,

wiggled the steering wheel

inserted the key into the slot

held the key up on the push start



tapped the steering lock module

took out the steering lock fuse,

checked the BCM for water damage,

replaced the key fobs battery’s,

replaced all electrical fuses

only thing I haven’t done is replaced the BCM, steering lock, and keyless entry module. I’m currently looking for the keyless entry module as we speak. Any ideas?

 

Have you tried with another key?
just trying to rule out if the issue is with the keys or something else.

 

Don’t have another one 😬

 

Ended up being that it was just the cheap key failing. Got new key and everything worked

 

what did the dealer tell you about this
