Lock,unlock on outside handle does not always work

[Stevegmc]

I have a 2018 Yukon Denali xl that the button on the handle to lock and unlock only works periodically, I have taken it in to a dealership twice the first time they could not duplicate it and the second time they replaced the battery on the remote which still hasn’t fixed the problem, the strange thing about the problem is I keep my remote in my pocket and then touch any part of the remote (even the plastic portion of the remote) and it will most of the time lock and unlock my vehicle this process works about 90 percent of the time the other 10 percent of the time I have to manually hit the unlock, lock button

Does it work out of your pocket? Mine is picky sometimes depending on what's in my pocket with it.

Sometimes even if I take the fob out of my pocket and put it right next to the door handle and its button and the button still
Does not work and sometimes it does
