Where is the Jaguar XJL key signal induction located?

Jaguar XJL key signal induction is located on the side of the car key. Jaguar XJL key working principle: First, the key emits a weak radio wave, which is received by the car antenna. The electronic control unit then identifies the signal code, and finally, the actuator motor or electromagnetic coil of the system performs the lock/unlock action. Jaguar XJL key recognition troubleshooting: If the key cannot be recognized, first ensure that the key has not been exposed to water. Then proceed with programming checks, key module inspection, receiver inspection, circuit inspection, or replacement of a new keyless module.
As an owner of an older Jaguar XJL for five years, I can share some insights. The key sensing area is near the door handle, where sensors detect the key within about one meter to unlock the doors automatically. Inside the car, the start-up is even more sensitive, especially around the gear shift knob and under the center console—placing the key near the cup holders is the most reliable during startup. When the key battery was running low last time, I noticed the sensing distance decreased, so it's a good reminder to replace the coin battery regularly. Here's a lesser-known fact: there's also a hidden sensing point in the lower right corner of the trunk—the key needs to be nearby for the foot-activated trunk opening to work. During the rainy season, interference can affect the sensors; in such cases, placing the key close to the emergency sensing area under the steering wheel will allow the car to start.
Repair shops frequently deal with luxury cars like the Jaguar XJL, whose key sensing system is thoughtfully designed. The exterior sensing points are concentrated on the inner side of the door handles and beneath the trunk emblem, while the interior has three locations: the storage compartment under the center console, the base of the front center armrest, and behind the start button. During actual repairs, it was found that placing a metal water bottle in the cup holder can interfere with the sensing, as can placing a phone and the key together. After replacing the smart key battery (CR2032), the sensing distance can be restored to about 1.5 meters. In emergencies, pressing the start button with the key or inserting it into the slot below the steering wheel can start the engine.
