Unlocking all doors using key on 2016 Sierra?

[Mileguru]

 

I can't lock with just the key, it will only lock the drivers door. Is there a setting I can change to lock and unlock all doors with just the key?

 

I also cannot get just the key to lock all four doors. It will only lock the driver's door.

 

I recently bought a 2017 CC SLT, and I'm trying to figure out how to use just the key (not key fob) to lock and unlock the doors without having the dang alarm go off.

 

Here's how it goes for me:

1) I have to use just the key (not key fob) to go running or surfing

2) I then have to hit the lock button on the inside of the driver's door twice to lock all of the doors because the key alone will only lock the driver's door from the outside

3) I return to my truck and unlock the driver's door with just the key and the alarm starts chirping until I hit unlock with the key fob that I have to hide under the driver's seat

 

Very annoying! It SHOULD be able to lock and unlock all of the doors from the outside with just the key so the alarm doesn't get set.

In reply to myself (because who else is going to read this year old thread?), I figured out how to use just the key and NOT have the alarm chirp and/or go off.

 

1) Turn the ignition off with all of the doors closed

2) With all of the doors still closed, hit the lock button on the driver's door to lock all of the doors (the one where all of the window controls are)

3) Open the driver's door by using the door handle (you of course have to pull it twice)

4) Close the door and lock the door from the outside with just the key

 

When you return and use just the key, there will be no horn from the alarm.
