Re: Push button start/remote
When I first got my '11 I had several instances of "No FOB Detected". Just for grins I put a new Duracell in it and I bent the contacts just a little to have more pressure on the battery and all of my problems stopped. Now I try to remember to put in a new battery once a year or so just to be safe but I've never had a dead FOB battery.
When we picked up our '14 we were staying in a campground at a nearby lake. As soon as we parked it next to our '11, neither of them would unlock with the FOBs. We had to get the key out of the FOBs to unlock the doors on both. Once you got in the vehicles the push button Start would work okay. Just could not unlock the doors with the FOB, neither by touching the door handle nor by pushing the unlock button on the FOB. I thought the two systems were interfering with each other. But, we could drive both vehicles up to the local service station and park them side by side and everything worked fine. When we would go back to the campground, neither would work. Two days later, the motorhome across the street from us pulled out and everything started working on both vehicles. Never had a problem again. I think the folks in the motorhome had a wireless router or cellular amplifier that was interfering with the sensors.
