I've developed an intermittent problem.

The car isn't recognizing the remote when I approach the car and won't allow the doors to unlock (manually unlocking works but alarm goes off). In addition it will not start when blue button is pushed. I've tried inserting the key in the centre storage area and still no luck.

I have tried two different remotes and replaced batteries in both, still no joy. If I go away and come back it seems to work, sometimes or sometimes I move the key around in the centre storage area and it works.

Any suggestions.

Do you have a new 12 volt device on board, like a new Dashcam ?...What is the car's year ?. The fact is an intermitent problem makes the trunk 12V battery a suspect...Good luck , keep us posted.

Try a new key fob battery. There about a buck at the grocery store. I had to replace one of mine about 3 years ago.

Mine's doing the same, just started happening I have a MY13 Volt. I have found it is worse with my Bluetooth OBDII attached. My 12V battery might be going south it's getting cold now. I have replaced my button cell batteries as well.

My first thought was this it was the fob battery, but you've replaced that. My second though was that you had the fob in a pocket and the signal wasn't getting through, but you're saying it also doesn't work when you use the key in the storage area, and this method doesn't use a signal. Since it's intermittent my next guess would be the 12v battery. If you haven't replaced the battery I'd start there. You could take it to the dealer but the charge for diagnosing the problem would likely be the same as what it would cost to replace the battery.

Could be an electrical problem so some sort but (thankfully) we haven't seen many of these.

The dealer can test your 12v battery and if found to be defective they can replace for you right then and there.

The time this happened to me, I checked the 12V battery and the positive clamp was loose. I snugged it up and it hasn't happened since.
