Trunk button doesn't open trunk on a locked vehicle

Maybe I'm reading the Users Manual wrong. When I walk straight up to the trunk & click the button (on the back of the vehicle), the trunk does not open. But when I unlock the vehicle, it works every time.

I'm aware of the setting on the touchscreen to ENABLE/DISABLE the trunk button. I toggled it and left it on ENABLED. Same issue.

Any ideas why it doesn't work when the car is locked? :unsure:

I'm assuming you have the fob in your pocket, mine will open with the foot senor or the button on the tailgate with the truck locked.

Yes, the key fob is in the pocket. But good to check all the boxes first.

I didn’t buy the foot sensor add-on. And my tailgate does not open when locked. Might be (yet another) gremlin in the vehicle. 484F1BBC-B263-4620-BCAF-3FDFCCF51189.jpeg

UPDATE: Yup, you’re right. Found the part where it’s supposed to be working. Thanks.

Maybe the fob has a week battery. Maybe try the other fob. I didn’t know that the motion sensor for the rear hatch was an option. Thought that was included with the ST.

That's a good idea! I'll try the other key fob today. Thanks. (Will let you know the results)

there is a setting in the touchscreen that will lock the rear hatch. mess with that
I tried the other key fob. That didn’t work.

I also tried toggling the touchscreen lock button for the rear hatch. Even went so far to restart the car between toggles. No Luck.

There has to be something I’m missing. :unsure:

After getting the vehicle back from the dealership, they could not identify what is wrong with the trunk button. it works when the car is unlocked but not when locked (& with the keys in my pocket). I’m not too concerned but just annoyed I have to grab my keys every time I want to get into my trunk (when already locked).

Any ideas of what they could try to get if fixed?

Does it do that for the other key? Will it open when locked with the kick underneath the bumper maneuver? Just assuming it's the rear proximity sensor for the smart key.

The other key did the same thing. I though the battery on my key fob was low too, but no change.

The ‘kick underneath the bumper maneuver’ is an add-on, I didn’t buy that option. The dealership tested the rear proximity sensor, they said it’s functional.

These are all great ideas. What else can I try? :unsure:

Good question: Yes. Are the rear doors working off the rear proximity sensor?

I noted that upgrade from my Charger (where only the front doors unlock all the doors when you grab the handles). It is annoying when you have a kid to put in their car seat before getting into the driver's seat.

I'm not sure if there is more than one prox sensor but if the rear doors are unlocking the hatch is not but run on the same prox sensor may point you in the right direction.
