Inoperative Passive Entry and Passive Start Functionality

One or both of the Remote Keyless Entry transmitters, or key fobs, with passive entry and passive start (Fig. 4) functionality may be inoperative from initial use on some 2016-2019 CT6; 2017-2019 XT5; 2018-2019 Enclave, Encore, LaCrosse, Regal, ATS, CTS, XTS, Camaro, Cruze, Equinox, Malibu, Sonic, Tahoe, Traverse, Trax, Terrain; 2019 Envision, Escalade, XT4, Bolt EV, Silverado 1500, Volt, Acadia, and Sierra 1500 models. There also may be a “No Remote Detected” or “Place Key in Transmitter Pocket” message displayed on the Driver Information Center.

While the passive entry and passive start functions are inoperative, the buttons on the key fob are operational. In addition, the vehicle can be started using the backup starting method of placing the key fob in the cupholder or center console to enable the vehicle to start.

If these conditions are found, it may be due to invalid data stored in the key fob. Reprogram all key fobs (Fig. 5) for the vehicle. Follow the reprogramming procedure for Replacing Transmitters (with SPS) in the appropriate Service Information.
