Passive Entry

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

On vehicles fitted with the optional passive entry system, the vehicle can be unlocked without the use of a key blade or pressing switches on the Smart Key. The Smart Key operates the passive entry system in addition to the passive start system. For additional information, Refer to: ANTI-THEFT - PASSIVE

The passive entry system is controlled by the KVM and four LF antennas.

When a vehicle door handle is detecting a hand approaching the grip, via its capacitive sensor and the Smart Key is within one meter of the handle; the Smart Key receives the LF signal transmitted from the KVM. The Smart Key responds with a RF transmission of its authorization code. The RF signal is received by the RF receiver and passed to the KVM on the serial communication line, which checks and approves the code as valid. Once the handle is pulled to eighty percent of its travel the KVM then drives the fast latch directly to allow the door to be opened. The KVM also transmits an unlock request to the BCM/GWM. The BCM/GWM then passes an unlock request to the door modules.

Locking of the vehicle is performed by touching the dimples located on each exterior door handle, with the Smart Key within a one meter range of the vehicle. When the door handle dimple is touched, the KVM transmits a LF signal via the LF antenna to the Smart Key. The Smart Key transmits a RF signal which is verified by the KVM and allows the doors to be locked or double locked and the alarm system to be armed.

To double lock the vehicle, the dimple on the exterior door handle must be touched twice within three seconds, with the Smart Key within one meter range of the vehicle.

NOTE: The Smartkey may not be detected if it is placed within a metal container or if it is shielded by a device with a back-lit LCD screen, such as a smart phone, laptop (including when inside a laptop bag), games console etc.
