I've had a real problem with my key fob since I bought my ATS. I carry it with my other keys on a key ring just like every other fob I ever had. I have my house keys my truck keys and other misc. keys on the same ring along with my ATS key fob. My problem is the ATS fob seperates all the time! I'll pull my keys out of my pocket and half the fob stays in my pocket and all I have in my hand is the upper part with the key. I have had the fob come apart when taking out my keys to drive my truck and the important part falls to the ground. Today I was driving home from my sons house and realized that the lower part of the fob was missing from my key chain. After a few hours of looking everywhere and calling my son to look around his house I found the fob in my truck. It had fallen off my key ring when I was loading up some tools before coming home. I love my ATS but the fob is a lousy design destined to leave people stranded holding the wrong part of the fob. I have had fobs from other manufacturers and never experienced anything like this before. My Audi had a button to seperate the key just like the ATS but you could never do it by accident because the button was recessed not sticking out like the ATS. Has anybody else experienced this? I think I'm going to glue my fob together so it can't come apart anymore because it comes apart way too easily and I know I will lose it for sure if I don't.
