A few weeks ago, I hop in the car "Key Fob Not Detected"
I figure it's a fluke, take out the fob out of my jacket pocket and it starts right up - Great

A couple of days later, same problem, happening a couple of times a day
Next few days nothing .

This has been going on with no apparent pattern. I can hit the button to unlock or lock the car with no problems or pop the trunk , battery seems fine .

That's when I noticed that the issue only seems to happen when I have the fob in the same pocket as my iPhone .

I figure that i must be a bit crazy, so I just take out the fob and place it directly on my iphone in the center console - "Key fob not detected"
I move the phone away - car starts right up

I put the phone and fob in the same pocket - "Key fob not detected"
Move the phone away - bingo

I place the fob and phone right next to each other "Key fob not detected"
Move them a couple of inches apart - car starts

Being a network engineer I know a bit about phone/wifi/cellular frequencies
US voice operates at about 850MHZ
Wifi is over 2GHZ
Bluetooth is the same at 2400Mhz or so

It appears that car fobs (at least according to what I saw online) operate at a much lower frequency range, anywhere between 200 to 350Mhz.

So I have no clue what the heck could be causing it - the only change I could think of is that a few weeks back I upgraded to an iPhone 5S .

I tried the same experiment with a friend's droid - and no issues

Has anyone else experienced this madness?

Seriously
At this point I'm just curious as to what's causing it .
Maybe Angry Birds app?!

Mine does that when I park next to a store I use. I think it is the security system in the store that mess's with it.

I've had this problem on other vehicles. Hard to say why the interference happens sometimes, I usually just adjust my pocket and it works.

Keyless/remote fobs seem to use battery faster in my experience. Like kidcharger said, change the battery.

It's more apt to be harmonics or cell phone power that cancels out the fob signal.

I had this happen a day or two ago. Fob was in my jacket, Door handle unlocked, Jumped in and got the same message.
I took the Fob out of my pocket and it started right up.
I don't have a smart phone just an old cell for work. I was wondering the same thing.....

How far is the range of the Fob for locking/unlocking out in the open?
Mine is maybe 100 ft.

It might be a weak signal (so that someone couldn't steal your car if your keys are a short distance from your car) then it might not be able to read through your clothes either.
