2018 Suburban with the same issues. Sometimes it will work great but most times the vehicle won’t register the fob even when less than a foot away. Very frustrating. 
 

Anyone received resolution?  I’ve changed batteries and tried both remotes several times.

Just picked up a new 2019 LS, same issue.  Dealer agreed range was poor, and a loaner they let me use did NOT have this issue at all.

Said they'd 'open up a ticket' with GM on it.  

Remote FOB phone app works great.  But I don't want to pay 15-20 bucks a month for THAT service.  A 50+K truck should not have issues like this, every other vehicle I've had with RS worked flawlessly...

Thank you guys, and yes to all of your points.  We have even changed out the FOBs for entirely new ones, and flashed the system again, and I'm still having problems.  They have now ordered door unlock sensors to see if this helps.  I have been as close as 20' away, no obstacles in the way, and can hit the lock or unlock button......crickets!  VERY strange, as my 2017 2500HD FOBs work just fine, and always have.

Same issue on my brand-spanking-new 2019 Tahoe.  Did you get your problem resolved by the replacement door unlock sensors???  Be good to be able to tell my 'service' department I found the fix.  They have, they say, opened a 'ticket' with GM...

Been having the same issue from purchase Found some BCM codes and cleared them. Range for key fob increased a lot. No more message saying key fob not found. One code was B3105 - deals with key fobs. Hmmmm. Codes have not returned.

Thanks Bob2C.  I do not have any error messages about the Fobs not being seen/programmed.  Just doesn't work very well.

I had an '05 Malibu and it would remote-start if I could SEE it....

 

GM is going to replace the 'antenna amplifier' on my '19 Tahoe.  Part is in, but 2 weeks to install appointment, was to be today, but they cancelled citing "no GM tech on duty this week"... Great service... NOT... 

I'll report on fixed/not fixed after the appointment.

What did you use to scan? I had a generic obd reader with the obd scan software from App Store and it wouldn’t read these codes. Only bluedriver did. I don’t know about the other wire ones. Just something to keep in mind.

I have the same issue with a 2019 Suburban I just bought.

Took it to the dealer around the corner from my office 1st thing this AM out of convenience.

I showed them the bulletin, PIT5665.

They basically pretended to have never heard of the issue... BULLSHIT

 

They told me they were done just before lunch.

I picked it up and they said "no trouble found".. BULLSHIT... $46,000 worth of BULLSHIT.

 

I should have known better... A kindergarten class could provide a better source for mechanics than this place... They SUCK.. And I have had bad experiences with them in the past. 

 

I demonstrated the issue... the service writer ignored me and then after pushing the button like 20 times it worked and he looked at me and said.. see it's ok... try new batteries... I put in new batteries in and nothing, no improvement.

 

I am taking it to a different dealer.

 

Also I am going to video tape this issue. This is CRAP. My 2013 Sierra has remote start and it works from inside my building 50 yards away from it. (With aftermarket fobs no less)

 

Has anyone had a dealer replace the Antenna Amplifier like it says in the PIT? Did that fix it?

 

Luckily my neighbor's kid is the service writer at the next stealership I am going to and he may be a bit more receptive to actually DOING SOMETHING!!!

 

The part that REALLY sucks that if this does not get resolved it will DESTROY the resale value of the vehicle.

As stated above I used blue driver. I know some have mentioned that gm has a bulletin out in using blue driver because it over loads the canbus module but I was experiencing the same issue. I had the blue driver do a deep scan and it pulled several body codes and one u code I believe. I cleared them all and my remote works fantastic based on my experience. I lived with the short key fob distance for several months and just kinda stumbled upon it.

Thanks.

This is "Blue Driver"... $99 from Amazon?

I have a lower end OBD II scan tool. I may try that first and see if it picks up anything.

Did you get have any lights on the dashboard before before you used the BlueDriver scan tool?

BTW one of my colleagues has a 2019 Tahoe and he says it starts from 150' away from inside the building no problem every time.

Yes it’s the blue driver from amazon. I had a generic one and used the OBD app and it did not pick up these codes. I had no lights on.

Yes once I cleared those codes my remote works like 200 ft away and from my office through the window I can start the car. Before I could not which made me pissed because my Kia would start from the same spot.

At least your dealer is going to do something. The one around the corner from my office said "no issue found" and when I wrote them a letter saying the problem was still there and being a little bitchy about it the service manager called me and told me (in so many words) to F off and he would not look at my Suburban again... This is the single WORST GM dealership I have ever run across.. Bob Jeannotte;'s in Plymouth Michigan. This is not the 1st service issue I have had with them. It's the 3rd.

 

Who is your dealer and where? I am going to take it to one closer to my house...

Excellent information and is the answer to what would have been my next question.

What I don’t get is why the dealer don’t acknowledge these codes and clear them. They have the correct tools that are designed for these vehicles and I can find it with a $99 tool, clear them and my problem is solved. Crazy

They don't take the time to check them.. or most don't... They won't do ANYTHING unless (1) GM says it's a real fix with a TSB and/or (2) They are actually one of those 1 out of 100 stealerships that actually cares bout their customers and has the " I would rather make $5 from you 3 times than $10 once" attitudes.

      Hey all, 
      I have looked and looked for more clear instructions on how to program a second key fob for my 2020 Silverado (dealership lost 2nd set). I live 8 hours from where I bought the truck and the dealership I bought it from would need the truck to program it. I am trying to do it myself. I have followed this guide but still no luck. The youtube video that is out for it is if you are programming a key fob without already having one programmed. It wasn't much help for me. Any GM Mechanics have a quick write up they can copy and paste would be appreciated. 
       
      These are the two things that haven't been enough help for me.

      Hey all! I am new here, but have a very frustrating item on our new (to us) 2018 GMC Yukon XL Denali. The buttons on the exterior door handles that lock and unlock are driving me crazy. I think these are called passive entry buttons (not sure on the actual name). Both buttons on the passenger side work just fine, but neither of the ones on driver side work. They depress, but nothing happens. I have checked all fuses that may be associated with this system and they are good. I have went thru settings on infotainment system with no luck either. Please tell me someone else has seen this problem and can help me out! Thank you so much!

      Yesterday on GM Authority (they had a story about vehicle-mounted keyless entry key pads (not fobs) http://gmauthority.com/blog/2019/10/keyless-entry-keypad-offered-as-gm-accessory-for-buick-chevy-and-gmc/.  After a little more research and reading I have found that you can buy it as a kit and have the dealer or someone else install it.  So I have a couple of questions.
      1. Can I get it for my 2014 Silverado LT?
      2. Does the installer need to be a dealership technician?
      3. What is the general quality review of the new system?
       
      Thanks!

      I have a 2019 Chevy Silverado 1500 and my key fob only has the lock/unlock, and the panic button on it. I saw that the official Chevy accessories page has the key fobs with remote start, tail gate unlock on them as well. If I get one, will I be able to have the dealership program it on my current truck so I can have remote start or is this only for replacement for owners that already have the same key fob?

      My Ford F-150 didn't have keyless entry so I kept my keys in during one of my extended overseas trips, using the keypad to get in and my keys always safe. I could never stand the thought of losing my keys 6,000 miles away and having no way to get in my truck and I wouldn't be able to get in my house! I learned it the hard way a long time ago, never again.
       
      I didn't know my Chevrolet came with keyless but it was attached to a fantastic deal I couldn't refuse so I had a dilemma. I could use my phone to unlock my truck so I didn't really need the keypad my Ford had, but I just may install one for $250 at the dealership anyway. That's just in case I lose my phone whilst overseas.
       
      Unfortunately, keeping the keyless fob around the new Silverado will cause battery drainage as the module will be kept active when the keys are detectable. My truck didn't lock when I was at the back of my truck. As one member said, the Hitch Safe wouldn't be good enough and he's right so it was no longer an option. One here suggested wrapping it in aluminum foil and I tried that. It worked very well and realized my Progresso soup can had thicker aluminum so I tried it with the smooth-edge can opener and, voila!
       
      I am very pleased to report my truck did not unlock when I held it inches away from the door. To think I was going to spend $19.99 for a can of Coca-Cola with a secret compartment!

      Now, my question is: if I used my phone to unlock the truck from a distance... how long would the battery last before it dies? Can it do a month?
