Hi,
2011 rogue sv with 2 fobs. 127k
They proxy unlock thus far works fine, no "low battery" warning since I changed the battery in one a year ago.
My wife and I both were sitting in the car and we both had our fobs on us, car said key not detected.
Worked fine this morning but on Friday the proxy unlock worked without the ignition detecting the key once inside.
I searched but I keep finding "change you batteries!" and not much else.
One fob had the Batt changed a year ago I think they other was 2 years ago... I don't think they both died at the same time.
This is one of those times I'm glad my car doesn't have a button start, so glad it still has a traditional key that I can whip out (and in!) !
