I noticed this in the fall when I would play golf and throw my keys in the golf cart, play a quick nine holes, and when I get back to the car, the key fob won't work. It works fine again once its been in my pants pocket long enough to warm it up again, but it seems like if my key fob is any cooler than like 55 degrees, it doesn't work. Now that its January, I can't even keep my keys in my jacket pocket without it failing on me. Anyone have any ideas on what is going on?

Also, its probably worth mentioning that my car does not have the key-less ignition option.

I would check to make sure your cell phone isn't interfering with it. If I have my cell phone near the keyfob or center console, it doesn't recognize the key fob.

I'd replace the battery. I *do* have the keyless ignition option, but mine acted really weird when the battery was dying (never got a message about a low battery, though). Batteries don't like the cold, so if it's going dead anyway, that might explain why it's finicky.

As an aside, I would highly recommend taking the remote to your dealer and having them change the battery for you. Even though the battery will be more expensive from them, if they break it, hopefully they'll replace it for you. Mine cracked when I tried to pry it open according to the instructions manual. Fortunately, the car was still under warranty at the time and the dealer replaced it for free.

Like reciprocity, I recommend consulting with your dealership about this fob concern. And if you would like me to contact them on your behalf, please feel free to email me anytime. I'm reachable at [email protected]!

I appreciate the replies, I definitely plan on replacing the battery at some point, so far I just haven't taken the time to get a new one.

Akamai43, its not my cell phone interfering, sometimes I don't even have the phone with me when this is happening, I appreciate the input though!

And reciprocity, I hear what you are saying about how fragile these things are, in fact when I bought the car back in August, the dealer handed me the #2 fob and it was wrapped (poorly I might add haha) with clear shipping tape to hold the two halves together. I've already taken it apart a few times though and so far so good. Its probably a safer bet to take it to the dealer, but I tend to avoid the dealers whenever possible haha

Just like your car battery in the winter, batteries do not have the power when cold like they do when warm. You have just proven that theory. Replace your battery.
