The passive key also contains a removable key blade that unlocks the driver door in the event of an electrical failure (such as a drained battery). The passive key requires 2 batteries. They should always be replaced as a set. For battery replacement instructions, refer to the Owner's Literature.

To start the vehicle in the event of a passive key battery failure, place the passive key in the backup starting location. Refer to: Passive Anti-Theft System (PATS) - System Operation and Component Description .
