Has anybody else experience this issue?. I have noticed that in cold weather when the key fob gets very cold it's stops working. Yeasterday, I had my fob in my jacket pocket when I stepped out of the ca for 45 min or so, it was 20 degrees outside and when I came back to the car the fob was unresponsive , however once it warmed up it continued to work fine. This has happened to me a few times and I have checked the batteries and they test fine.

I did have that issue as well. It would work fine during the day, but then as the temps dropped overnight and I would be outside, the fob did not want to open the door. I had to hold the key in my hand a few seconds before it would work. I did end up having the batteries replaced when I got a new fob (did not come with 2nd fob) and haven't had that problem since.

Repost...
Perhaps you could change the batteries anyway and see if that works.

We had 3 days of minus 25-33 degrees this week in New-Brunswick and I was able to use the key fob. I do not know why yours is not working...

Basically, when exposed to cold for long periods of time it refuses to work. My spare fob is in the garage and it too does the same thing, if I bring it into the house for a couple of minutes it warms up and works again ..... Perhaps a change in batteries is in order even though they test fine.

Aren't batteries new or old less effective when cold? Perhaps try a couple days of leaving the fob inside overnight then testing it in the AM?

They typically are. I'd try changing the batteries first and then continue testing.

Like all the other responses. Change the batteries. The voltage lowers when cold so if the batteries are on their way out, it will stop working when it's cold. Does you car crank at the same speed at 10 degrees as at 70? Nope. The voltage is lower and the battery can't deliver the necessary current. Same thing with the fob. Some auto parts stores have a display in front that checks to see if your remote is transmitting properly.
