Intelligent Key Fob Not Working

2009_370z · 11-11-2015, 02:47 PM

Did you get the right battery? And put it back in correctly? This literally happened to me a week ago as well. I bought some from OSH and they were brand new but my fob wouldn't work. For a second, I thought I needed to replace my key fob but I decided to buy batteries from Walgreens and it worked again. Maybe you bought faulty batteries like me. Give it a try IMO. Keep us updated..

When I went in to work on it in the morning, I plugged the negative terminal of the battery back in and tried to lock the car with the remote but it wouldn't lock. The key wouldn't get registered by the car, and all it said was "No Key" on the screen to the left of the speedo.

I replaced the battery in the remote, but it still is not getting recognized. The only way to start the car is to put the fob into the port on the left side of the steering wheel.

What could be the issue? The fob was working perfectly fine before so I'm stumped. I checked the fuse box inside the car, and fuse box 3 inside the engine.

It's a 2012 370Z.

Thanks for any advice.

Thanks for the reply! I ended up having inserted the battery into the remote facing the wrong way. My other car key fob used to take the batteries in that way, so I thought they were all inserted the same way lol. I flipped the battery around and it works! There is also an illustration on the inside of the fob above the battery that I noticed, and it shows you how the battery goes in, Negative side facing up.

LOL, glad that all is well. I was going crazy because I had it in correctly with the right battery but mine wouldn't work. Lesson learned to never buy batteries from OSH haha.

Definitely! I was heading to the worst case scenario but thankfully it was something very simple.
