I've had my 2011 CTS-V for over three years now and the keyless feature is great. If I get paranoid about hackers, I have an RF shield that I can use, and I do keep that handy for traveling. But I find that the fob needs a battery after a few weeks or I get an increasingly weak signal from it until I must put it in the center console or even the fob pocket to start the car.
It starts out with an occasional "Key not found" message when I first get in the car. If I turn the keys in my pocket so that the Cadillac fob is not under metal, that works. For a few weeks, then I have to take it out and plop the fob in the drink holder.
Changing the battery makes everything OK again. Checking an old battery gives a reading 3.01 Volts, which is down from a new battery (more like 3.5 Volts) but not enough to kill the fob. And, it should need a battery every year or two, not every month or two.
Anyone have any comment on this? I'm reluctant to take this to a dealer until I understand the problem better.
