Sure enough I get a "Fob Not Recognized" message last night when moving it inside for my better half to avoid the first freeze of the winter. And it's so dark & cold I can't even discern where the heck to place it.

 

Question for those with expertise in this topic: how vulnerable are JLR’s key fobs to attacks like relay attacks? A neighbor got their G-Wagen stolen and from the looks of it it was a hacking job, which made me curious and go down the rabbit hole of modern key fobs and their vulnerabilities. So trying to understand what our key fobs do or don’t (e.g., go into sleep mode after the fob has been static for a certain amount of time) and how that changes by model year as I assume as these things evolve newer cars might have more protecting measures. Any insight would be helpful, as I am getting paranoid and looking at Faraday boxes to keep our car fobs in the house 🙂.

 

Land Rover (JLR) key fobs, particularly in newer models, feature sleep modes or motion-sensing technology to prevent keyless relay theft, where thieves boost the signal to unlock vehicles.

Key Fob Sleep Mode & Security Features

• Motion-Sensing Fobs: Newer Land Rover key fobs (generally 2018-2021+ depending on model) have built-in motion sensors. If the fob remains stationary for a few minutes, it will automatically go to sleep and stop transmitting signals.
