Key fob won’t work when at my home

[Vik]

I have a 2019 Serria 1500 AT4 and when I’m at home the key fob won’t work unless I’m standing right beside the drivers door , the dealership claims it’s cause of my neighbours aftermarket command start looking for options to fix problem

That makes no sense.  If that were the case, everyone would be having trouble with their fobs anytime they park at a mall...

 

maybe try putting in a new battery in the fob, it might be weak?

Well, there's some kind of interference keeping it from working.  We see this when programming remotes and TPMS.

I've gone to various locations around our city to help customers who call in saying they can't get in or start their cars like the fob is dead. Usually it is interference as once I remind them how to get in and start the vehicle with a non-recognized or dead fob and get them to move the vehicle 100 feet away, it works just fine. We even have an employee who can't use her Cruze fob in front of her apartment due to the guy below her having a bunch of various radio and scanning equipment. Again her fob works anywhere else.

 

If it works up close to the vehicle, it is likely a battery or signal strength. These new fobs with the keyless open on the doors are constantly sending out a signal (versus old style that only sent a signal when you pushed a button) so the vehicle recognizes when you approach the vehicle, and this kills batteries faster. It is not uncommon to see customers come in with battery issues in under 1 yr.
