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.

NOTE: The smart key may not be detected if it is placed within a metal container or if it is shielded by a device with a back-lit Liquid Crystal Display (LCD) screen. For example a smart phone, a laptop (including when inside a laptop bag), games console.

If the vehicle is equipped with the passive entry system, the vehicle can be unlocked without operating the switches on the smart key. The smart key operates the passive entry system in addition to the passive start system.

The passive entry system is controlled by the Remote Function Actuator (RFA) and the 3 Low Frequency (LF) antennas. Each exterior door handle comprises capacitive sensors to detect when a hand approaches the handle.

The RFA activates the LF antennas, when:

The vehicle is locked and the sensor within exterior door handle detects a hand approaching the grip,
And the smart key is within 1 m (3.28 ft) of the handle.

The LF antenna emits a 125 kHz LF signal that excites any smart keys in the vehicle's vicinity. Once a valid smart key receives the LF signal, the smart key responds with a Radio Frequency (RF) coded transmission. The RF coded signal is received by the RF receiver and passed to the RFA on the serial communication line. The RFA checks and approves the coded RF signal as valid.

Once the exterior handle is pulled to 80% of its travel the RFA then drives the fast latch motor in the door latch directly to allow the door to be opened. The RFA also transmits a passive unlock request to the Body Control Module/Gateway Module (BCM/GWM). The BCM/GWM then sends an unlock command to the door modules. The door modules drive the door latches to the unlocked state.

Locking of the vehicle is performed by touching the lock switches (dimples) located on each exterior door handle. A valid smart key must be within 1 m (3.28 ft) range of the vehicle. When the lock switch on the exterior door handle is touched, the RFA activates the LF antennas. The LF antenna emits a 125 kHz LF signal that excites any smart keys in the vehicle's vicinity. Once a valid smart key receives the LF signal, the smart key responds with a RF coded transmission.

The RF coded signal is received by the RF receiver and passed to the RFA on the serial communication line. The RFA checks and approves the coded RF signal as valid. The RFA transmits a passive lock request to the BCM/GWM, which then sends a lock command to the door modules. The lock command is sent via the High Speed (HS) Controller Area Network (CAN) body systems bus. The door modules drive the door latches to the single locked or the double locked state.

To double lock the vehicle, the lock switch on the exterior door handle must be touched twice within 3 seconds.
