Enabling and Disabling Passive Unlocking

The passive unlocking feature (RPO ATH) can be enabled and disabled on 2019 CT6, Escalade, XT4, Bolt EV, Camaro, Cruze, Malibu, Silverado 1500, Spark, Suburban, Tahoe, Trax, Volt, Acadia, Sierra 1500, and Yukon models, excluding vehicles equipped with the Remote Ready Start Package (RPO AP8). This is a new feature of the keyless entry system for the 2019 model year.

If the passive door unlocking feature is disabled, the doors will not unlock when pressing any door handle button (Fig. 6), or the tailgate will remain locked when pressing the tailgate release, and the turn signals will flash quickly four times.

The passive unlocking feature can be cycled between enabled and disabled using the Remote Keyless Entry transmitter (key fob).

To enable the unlocking feature, with the vehicle off, press and hold the Lock and Unlock buttons on the key fob (Fig. 7) for three seconds. The turn signals will flash four times to indicate that passive unlocking is now enabled.

With passive unlocking enabled, the doors will unlock when pressing the button on the door handle. On the driver’s door, press the button once to unlock only the driver’s door and press it a second time to unlock all doors.

 

Passive Unlocking Disable

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 turn signals will flash four times to indicate that passive unlocking is now disabled.

With passive unlocking disabled, the doors will remain locked when pressing the button on the door handle.

If there is a concern with the operation of the passive locking and unlocking system, ask owners where the key fob is kept or if multiple drivers use the same key fob to help determine if the system has been disabled inadvertently.
