Subaru Ascent 2018-2026 Owner's Manual: Access key fob - if access key fob does not operate properly

CAUTION

Keep metallic objects, magnetic devices, and signal transmitters away from the space between the access key fob and the push-button ignition switch in your Subaru Ascent. Such interference may disrupt communication and prevent proper system operation.

The following features of your Subaru Ascent may stop functioning correctly due to strong external radio interference or a weak battery inside the access key fob.

  • Locking and unlocking the doors, including the rear gate
  • Switching the ignition power status
  • Starting the engine

In these situations, follow the procedures below to restore operation. If the issue is caused by a depleted battery in the access key fob, replace it with a new one as soon as possible to maintain reliable performance of your Subaru Ascent.
