2016 Yukon Keyless Start System.

Hey everyone! I have a 2016 Yukon and my passive lock/unlock buttons on the door handles are not working. I saw a thread with a similar problem but wanted to ask if anyone could tell me where the antenna for the keyless ebtry system is located? I wanted to replace it, but not sure where it's located. Thank you!

Assuming you have passive entry (ATH), there are multiple antennas for different parts of the vehicle.

The keyless entry door antennas are located in the left front and right front exterior door handle bracket. The antennas are serviced as part of the door handle assembly. The antennas are controlled by the keyless entry control module. When the exterior door handle button is pressed, the respective antenna will send out a challenge to the keyless entry transmitter, which begins the passive entry communications.

Thank you for your response. So does this mean I will need to purchase the door handle assembly?
