It seemed like the fob to me, too. I wanted to check to see if there was anything behind the scenes...wasn't sure if the antenna that receives the signal could go bad. Unfortunately, I checked with my fleet manager and this is the only fob that it came with.

I tried the search but came up empty. I have a 2014 Silverado WT as a work vehicle. A couple of weeks ago the drivers door just started unlocking itself, both while driving and while parked- not a nice feature if you like to keep your belongings secure. One person suggested that the alternator was (somehow) to blame, and the shop tested it and replaced it, stating that it was putting out too much voltage, and replaced the battery at the same time. Within one day it began again. To spare the details, I traced it to the key fob- with the battery out of the fob, the doors do not try to unlock themselves anymore. A brand new battery did not fix the problem. Has anyone else had this happen? Is my problem the fob, or is it inside the truck with whatever receives the signal from the fob? Anyone know anything else to further diagnose? I CAN just take it to the dealer, but then I'm sitting around for half a day. Thanks.
