Recently my key fob keeps going out of sync with the car. It works fine after resetting and I have tried changing the batteries a few times - even with a different brand of batteries in case one set were bad! Normally it works for a day or two or even a few weeks but then suddenly appears to stop responding. Resetting the sync then reactivates it until the next time which can be the same day or more than a few weeks. When working the range is pretty great and the car responds from about 30m away without issues. There seems no logic as to why and when it stops again. Any ideas?
