Strange problems with wireless keys using multiple key fobs
 

Hello all,

I'm driving a 2012 with 149k currently, and recently I've started noticing issues with the key fobs.

I still have the two key fobs that came with the car when I purchased CPO in 2016.

I've recently replaced batteries in both key fobs, and have been swapping back and fourth. Seemingly randomly, they will each stop working. This includes the keyless unlock from the fob, the button on outside of the door, and turning on the ignition wirelessly.

When I stick the key fob in the slot (fobgina) it makes no difference! I've already almost been left stranded twice because of this, and the only way to make it work is to repeatedly press the unlock button on the fob until it starts working, then the wireless key will work perfectly for the ignition and I haven't needed to use the fobgina in either case.

Any ideas what could be causing this issue with the car? It happens regardless of which key I use, and I believe they are both genuine Nissan keys since I bought the car CPO from a Nissan dealer.

Since it is affecting both fobs, possibly an antenna problem. If it was just one fob acting up, I'd guess poor contact with the fob battery or dirty buttons. There are several antennae in the car; FSM (link in sig) will show you where and how to get to them.

Thank you for your reply, I will look into the antenna. Still seems strange that the slot doesn't work though when this occurs.

I had this problem at only 25000 miles. Turns out the FOB was broken. I got it replaced and it was fixed. It could also be the antenna though. Unfortunately, you’ll have to consult your local dealer.
