Panhandle Chevy

same exact situation for me. Seemed to be fixed and then it started again, although not nearly as often. Ended up buying the fob and programmer that you did (saw a couple of videos on install) and the issue seems to be corrected!! Save some $$ for sure! https://www.amazon.com/dp/B0CPDJMFH9?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1

Just as most of you, randomly my 2015 Silverado started unlocking every 10-15 seconds, driving or parked. Narrowed it down to the key fob. Replaced the battery but that didn’t work. Bought 2 new replacement fobs and switched the circuit board to them so I didn’t have to reprogram, same issue. but then Florida Jason mentioned checking the circuit board for some gel like substance and wouldn’t you know, mine had that on there. Wiped down the board and put the key fob back together. Tested it to make sure it still worked and it’s been 2+ hours and haven’t had the unlock issue. Getting ready to head out for the day, so I’ll report back. Fingers crossed!!
