Passive Entry Rear Handle

drmilesbennell · February 28, 2023

Hey all,

I have a 2022 Sierra SLT with passive entry locks on the front handles. Does anyone know if I can easily add passive entry locks to the rear handles? Acquiring the actual handles would not be the issue but I'm wondering if there is a harness (or whatever powers the front passive entry buttons) in the rear door to begin with. I know they come standard on Denali, so was thinking GM might just leave the wiring in the door for different trims but not include the passive handles all around. As I type this, though, I'm sure there's programming that needs to be done but figured it was worth a shot - because why not!

Any help is appreciated, thanks!

I just picked up a 23 GMC and the dealer told me they aren’t putting on the rear doors due to chip shortage? So if that’s a fact I doubt it’s something that’s already there, but if you figure it out let me know as I already miss that option from my 2019.

I would like to know the same.

I heard Ford quit doing the rear button on many trim levels couple of years ago. Data showed they were not getting used that often. Cost cutting.

My guess is that GM did the same, for the same reason.

I heard the same, it's chip shortages and I also believe a cost factor. Had the button on all 4 handles of my 2019, getting used to having it only on the front door handles of my 2023. I see other manufacturers doing the same, it's not just GM.

It may depends on the model year as well as trim.

My '23 Denali does not have buttons on back doors. (I think my '21 did.)

So, any salesman or dealership blaming this on chip shortage is uninformed. It's simply a cost cutting move.

I set out to add rear passive button handles on my 2024 1500 Denali. First, none of the necessary wiring is in the truck, in either the door harness, or the body harness. The (passive) rear door handles have two wires. One is ground, the other is 7v signal. The button simply grounds the signal, telling the module to check for FOB and do it's thing.

With that said, I have successfully added a rear passive entry handle on my driver side rear door. The other handle is on order. You will need to remove the door panel, the center pillar panels, drivers kick panel, etc. The ground wire for the button can be tied into the door harness ground, and the signal wire will have to go tie in to the drivers passive button wire. On my truck it is pin 17 (blue wire) in the driver door, door/body harness.

If I hadn't been so used to having the rear buttons on my '20 AT4, I probably wouldn't go through the trouble of adding them. However, I constantly find myself trying to push the button to open the back door, only to have to reach to the front door.

Bumping this thread. Do you happen to remember the door handle part numbers?

Also, did you remove the center panel just for wire routing? I assume the wires were fished through the boot in the door jamb. How hard was it to remove the panel?

Thanks!

Did you order a harness for 20 truck or did you just wire it yourself.
