2019 Silverado keyless entry activation

[zanefair]

I just bought a 2019 Silverado lt. It has power locks. The AQQ option was not part of the build (from what I can find is the remote entry option). I have found a few people saying the option is there just need remotes and activate it in the BCM and program the remotes. Does anyone have any experience with this?

Welcome to GMT Nation...

(1) If you have not done so by this posting, get your hands on the 2019 Chevrolet Silverado APP called "My Chevrolet" or by a similar file name and install it on your Cell Phone. Then, check out many of the seldom described features available (but rarely disclosed) to the Later Model Silverado Owners ...as per the Videos below.

(2) As always... -=RTFM=- (Read The F***** Manual) FIRST ...if there is not a Brand New Owner's Manual found in the Console or Glove-Box... then Invest in one ASAP and visit the Index to seek making any adjustments that will require the combination use of the Dash Panel IC and-or the Key Fob(s).

(3) Be Fastidious and Thoughtful... Your Truck ..Well Understood ...Early in this Game.... will run better with less troublesome issues the More you Learn and Understand its idiosyncrasies... NOW, Don't trust any outcome to somebody else's Guesswork, Urban Myths, Downright BAD Information or from a Stranger having a Warped Sense of Humor that will send you unnecessarily down a vague Rabbit Hole and risk damaging your New Truck...

Happy Motoring!

You likely have a WT so very low options, worse than an LS. Ran this question by AI and the answer is yes and no.

Yes, it is entirely possible to add keyless entry to a 2019 Silverado built without the AQQ option code, provided your truck currently has factory power door locks. Because your truck has a Tire Pressure Monitoring System (TPMS), it already houses the necessary Remote Control Door Lock Receiver (RCDLR) hardware from the factory, which shares the exact same frequency needed for keyless remotes. [1, 2, 3]
However, you cannot simply buy a factory remote and program it yourself using a standard sequence. Because your vehicle configuration lacks the AQQ software file, you have to choose between a factory workaround or an aftermarket path. [4, 5]

Option 1: The OEM / Dealership Route (Factory Quality)​

To use a genuine Chevrolet key fob, you must get the feature enabled at the software level. [3]

1. Purchase an OEM Fob: Buy an official, basic GM 3-button key fob. [6]
2. Dealership Programming: Take the truck to a GM dealership. They will connect a diagnostic tool to your vehicle's OBD-II port using GM’s official software. [1, 5, 7]
3. The Software Catch: The dealership must request or pull the correct software calibrations from General Motors to change your truck's software profile and activate the keyless entry functionality on the RCDLR module. [3, 8]

Note: While the hardware is ready, some dealerships are more accommodating than others regarding flashing software for options your truck didn't roll off the line with. It is highly recommended to call your local service department first to confirm they are willing to perform this software calibration update. [1, 9, 10]

Option 2: Aftermarket Keyless Entry Kits (Easiest & Most Certain)​

If you want to bypass the dealership's premium pricing or software locks entirely, installing an aftermarket kit is a guaranteed solution. [11]

• 
  
• Standard Keyless Entry Kits: Any local automotive 12-volt electronics shop can install a basic aftermarket keyless entry system. This taps into your existing power lock wiring and bypasses the GM computer entirely, giving you aftermarket fobs to lock and unlock the truck. [11, 12]
• OBD Programmer Bundles: Companies like Simple Key or ProKeyBox offer bundles containing a key fob and a dedicated OBD-II programming tool. These bypass the dealership software requirement by injecting the code directly into the vehicle modules yourself. [13]
• Passive Keyless Entry (PKE): You can also upgrade to advanced, proximity-based aftermarket kits (such as systems from VAIS Technology). These systems automatically unlock the doors when you walk up to the vehicle and lock them when you walk away, mimicking higher-trim features without requiring factory RPO codes. [14, 15, 16, 17, 18]

A Warning on Remote Start​

While you can successfully add keyless entry, you cannot add factory remote start (RPO BTV) to a truck built without AQQ. The factory remote start upgrade kit requires a pre-existing factory keyless entry system build profile. If you want remote start down the line, you will need to rely entirely on an aftermarket remote start system. [1, 6, 14, 19]

If you would like to map out the next steps, tell me: Do you have a turn-key ignition or a push-button start? Knowing whether you prefer a genuine GM key fob or are open to an aftermarket system will also help me narrow down the exact parts you need.

So it is possible to enable it on your truck but you need a dealer level programming interface and possibly a customized program from ACDelco TDS to enable it, something us mere mortals usually can't get even with a compatible interface.
