2018 Yukon XL Decreased Command Start Range

[Dalien]

Recently, the range on my key fob has dramatically decreased. I replaced the battery which didn’t help. I tried my spare new fob which also didn’t help. I’m starting to wonder if it could be the module that receives the signal from the fob? Does anyone have any ideas what the issue might be or where that module would be located on my 2018 vehicle?
Thanks!!

2019 Yukon Key Fob Range Blows...What Would You Do?

My new 2019 Yukon key fob range is terrible. Literally 1/3 the distance of my 2018 Sierra. Almost makes the remote start worthless. Both key fobs have the same issue. The truck came off the assembly line in April and I bought it new in early June so unless they use old batteries at the...

Does the receiver antenna/module need to be programmed by the dealer or is it a matter of just plugging it in?

It just works when you plug it in.

I recommend buying some replacement clips ahead of time because I broke several.

I'm confused?? I went to the dealer to get a replacement Receiver / Antenna for my 2018 Yukon XL. The dealer sold me the 315 Mhz antenna part # 1358-6853. I went on Rock Auto and it lists the same part for my vehicle. Whats confusing is that the dealer showed me that the antenna is located on the passenger side rear pillar (3rd pillar). I was looking at Nickfire20's post which shows it under the roof liner with a short wire coming off the antenna and plugging onto the side window wires. My vehicle has the same wire coming out from the roof liner. The antenna that the dealer sold me does not look the same as the one in Nickfire20's post. Do I have the right part?? I haven't taken the panelling off yet so I guess it's possible that it is located on the pillar and the wire that is attached to the side window is long and plugs into the antenna I bought. The dealer and Rock Auto both say that the antenna needs to be programmed but other posts on this site say that they plugged it in and it worked. Any clarification would be greatly appreciated.
Thanks!
