I have the same issue on my 2008 Infiniti G37. The car started just being dead, but the remote would unlock the doors. When you are in the car, the amber key light on the tach just stays lit, and it doesn't see the keyfob, and the security light on the speedometer occasionally blinks. Car is dead other than that.
Originally a couple of weeks ago when it did this, I tried to bang on the module with a hammer and that didn't work. I then dropped the steering column and pulled the lock module box off and I pushed the plunger in, and put it back on , the car fired right up. While the car was running I then went and pulled the 10amp fuse to that lock module on the fuseblock under the hood behind the battery cover. It ran fine like that, no issues for 2 weeks until yesterday, it started to do the exact same thing. This time around I was able to hit the box with a hammer and the car started up and I immediately got it home and put it in the garage.
So I pulled the lock module apart and mine is all metal and has 4 contact switches. 2 small blue switches on a metal paw that attaches to the coil actuator that moves the metal lock pin up and down, basically to sense its position closed or open, and 2 small metal contact switches, the type that ride on a cam, on a white cam wheel that has the worm gear motor hooked to it. I tried like in the videos rotating that cam gear around to make sure all the switches were closed, even pulled the cam gear out also and stuffed foam into the hole to push down the two switches.
The furthest I get, is the car will now turn to the ON position and all the dash , stereo, fuel pump comes on but it won't run the starter. Just sits, same as if putting it on ACC to ON without pushing on the brake.
I have found only one Emulator on Ebay that claims it works on the 2008 Infiniti G37 and its from Turkey. I just got an email back from the guy selling says it does work on my car but $100 w shipping from Turkey, seems like it will take a long time to get it.
All these other emulators that are cheaper, the black ones, look like they are from China all say they are for Nissan 07-11 Altima 09-10 Maxima 2.5l 3.5L or Nissan part # 48700-9N00B
I cannot find a part # but on Ebay mine is shown to have the # 48700JK000. This is the ebay link to my module and what it looks like.

Does anyone know if the emulator will work on the 2008 G37 , thats the same engine as the 370, 3.7l v6? Its the same plug looks like. Maybe someone has a link to one they know works for Infiniti G37 Coupe or can recommend one? Thanks!
Also if I were to just buy a used lock module, do they have to be programmed by the dealer or a locksmith , or all of them are just a swappable part that doesn't need programming?
