Passive door lock not working.

It was replaced under the cpo warranty. They work fine on the passenger side however on the driver front and rear door they do not work. Through some investigation i have found that there is a second antenna system inside the rear passenger door. One is the battery powered section that operates the remote door lock unlock.

It will operate with a dead battery. The doors will not unlock if they do not sense the programmed matched fob. The second is a rfid like toll roads use and operates the passive entry and push to start. 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.

With passive unlocking disabled the doors will remain locked when pressing the button on the door handle. The dealer replaced the outer door lock handle had to have it painted before installation. Eventually it stopped working altogether. I went into a store left the car running and when i came back out the doors were unlocked.

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. You must remove the door pad to access this. The lock button is part of the handle assembly and is not available separately. The exterior passive lock unlock buttons on the doorhandles of my yukon do not work.

Got the service keyless system message then the next day all passive entry options were not working. To disable the unlocking feature with the vehicle off press and hold the lock and unlock buttons on the key fob for three seconds. There are multiple short range antennas in your gc including one around the perimeter of the spare tire well for tailgate operation.
