Passive Door Lock Not Working

I ve checked the settings multiple times and even turned off and on the passive door lock feature and it is on but it is not working whenever i leave my vehicle running the doors stay open any thoughts or.

Passive door lock not working.

Through some investigation i have found that there is a second antenna system inside the rear passenger door. Eventually it stopped working altogether. Got the service keyless system message then the next day all passive entry options were not working. There are multiple short range antennas in your gc including one around the perimeter of the spare tire well for tailgate operation.

It may return to normal. They work fine on the passenger side however on the driver front and rear door they do not work. Why don t you try disabling passive entry via the uconnect settings lock unlock the car via the fob and then re enable it in uconnect and try again. It will operate with a dead battery.

The exterior passive lock unlock buttons on the doorhandles of my yukon do not work. The doors will not unlock if they do not sense the programmed matched fob. With passive unlocking disabled the doors will remain locked when pressing the button on the door handle. To disable the unlocking feature with the vehicle off press and hold the lock and unlock buttons on the key fob for three seconds.

The lock button is part of the handle assembly and is not available separately. The turn signals will flash four times to indicate that passive unlocking is now disabled. The second is a rfid like toll roads use and operates the passive entry and push to start. I went into a store left the car running and when i came back out the doors were unlocked.

The other door lock buttons the remotes and the lock switch in the console all worked fine. One is the battery powered section that operates the remote door lock unlock. It was replaced under the cpo warranty.
