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

[pwtr02ss]

Good info. My remote worked great and then a few weeks ago, started being ******. Passive lock was hit or miss. I changed the fob battery but haven’t really driven the truck since. I wonder if this could be my issue. 2019 denali

More than likely this is your issue.

Update on mine....dealership did it for free. I dropped it off, 7hrs later I called because they didn’t, and of course it was done. They marked it down for 0.6hrs of work. Besides the headache with a typical stealership, it works great now!

It’ll probably give me cancer one day but I just hold the fob to my neck and the range is way better. Almost all the way across a Costco parking lot. Uses my body like an antenna I guess.

I've got a 2018 yukon xl denali with the same problem. Picked my amplifier up today from the dealer for $43. On the gm part system, it only calls it the radio amplifier. Installed in about 20 minutes. On the Xl very easy to access. Coat hook and the back corner that holds the speaker removed. Gives you enough room. You can see part of the unit hanging down, attached to the window antenna.

The amplifier fixed it for me.

Replaced the antenna amplifier on our 2019 Yukon XL today, short range/key not detected is definitely fixed. As GMC AK already indicated, installation is easy.

Hey @915_Tahoe can you help me with a part number please?

Rockauto now lists 4 different part numbers for this part. Can you confirm the replacement number? Last 8 of vin is KR133329.

My range has been getting worse and worse and now the passive system doesn't work 70% of the time and if my wife has her key in here purse, in the back seat, it will move the seating position to hers, even though I'm in the driver seat. Finally had enough and I want to tackle this project.

Gm parts direct is showing 84693389 but says "without satellite radio" and I'm pretty sure I have that function

You would have to remove the amp, to get the gm# thats labeled on it. Does show 2 gm#'s for that amp.

Thank you so much!

I ordered both parts. I'll post which one worked when I get them swapped out.

Just a quick update. I bought both part numbers and the original gave no signs to which one to use (other than the MHz). I opted to go with the 3389 part number as that's what everyone else seemed to be using. So far so good. Passive feature has worked every time and I can remote start from the very back corner of my yard (250' ish). Thanks to all of you guys(gals) for posting this. I hope it lasts because I don't want to have to do all that again
