I went to get into my truck yesterday and the button on the handle wouldn't unlock the truck. My fob was in my pocket and even tried all doors but nothing. I unlocked it with the fob and tried all doors and the buttons on them will lock the doors but not unlock them. 

Any suggestions?

1) Remote battery may be weak

2) Button is broken

3) Antenna in door not reading remote

 

That's where I'd start looking.  Title and original post aren't specifying if this is a door or doors issue.  Have you tried both (or possibly all 4 if equipped) doors?

yep same result with all 4 doors. The buttons will lock but not unlock the doors. I think the the fob battery is fine, it will work from pretty long way from the truck.

Check and see if the user profile has been changed. It sounds like the system is operational just a setting in the infotainment system has been changed. There is a setting that disables the door unlock button but will allow the door button to lock the door. I believe this setting can be associated with user profile.

You are right! Checked the settings and the passive unlock decided to switch itself off. 

Thanks for the info!

If you actually cared about customer satisfaction, the A with an arrow button that kills my engine would stay off until turned back on. That thing is the worst thing about my Sierra.

Seriously?  That's about as lame a post as I have seen in a long time ...............

lol you can thank your governmental overlords in the EPA for that one.

I couldn’t agree more. That button and the engine stop and having to push it after you start the truck every time is the most stupid engineering piece since the ejection seat on a helicopter.

Well, am I ever glad I saw this thread. 

 

Thanks @Truck RamRod !!

 

Mine quit doing the passive unlock the last week of August.  Passive lock still worked.   Attempting passive unlock and there would be a sound from under the hood, but doors wouldn't unlock.

 

If truck was locked, tailgate unlock/open didn't work either.

 

Same week the truck received / installed 4 OTA updates.

I never thought to check to see if maybe a setting was changed.... 

 

Asked about it on this forum (instead of searching) and go no responses.

 

Because of thread I went and checked.

Sure enough, passive unlock was turned off.

 

 

I'm now guessing that one of the updates changed the setting back to a default.

 

Anyway, it works now!

Press and hold the lock and unlock buttons on your FOB at the same time. This will reset the keyless entry on your door.

 

For months I have been trying to find the answer to this question and everyone just kept saying oh you just turned the passive unlock setting off even though that was the first thing I checked. Your solution worked right away, thank you for finally posting the actual answer

If you carry your fob in your back pocket it is pressing both the lock and unlock buttons at the same time when you sit down and that is what's changing your door locks. Just press lock and unlock button at the same time and hold them and it will correct itself.

    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.      
    • Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.
    • I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?   
    • Do you think this width might affect the chalk test with a higher pressure closer to 65psi? I think lowering the pressure makes sense to get the tread to lay flatter
