Land Rover did a recall of keys recently and allegedly have now put a super spy proof battery in my fobs which are now safe from poachers. Hmm.
Ours, the run out proper Discovery, the 4, was within a recalled tranche.
However, having its roots in earlier times its keyless system could not have the firmware update some of their products also got. Therefore, I was sent two "sleeping" batteries.
Logically to me if you remove the fob giving a signal when one is not needed, that has to massively reduce the opportunities to clone it. Leaving the thieves the challenges of working on systems grabbing the signal whilst I go in and out of fuel stations, car parks and home. Which has to afford them a very low percentage of the time available to clone, and require practically more portable kit.
My RAV4 fobs can be put to sleep, and reawaken when next used. I can now anticipate the next raft of posts.
That to me seems so logical a concept and has to be so technically simple, odd it never dawned on the designers of my earlier keyless system, some it probably did.
Pity JLR when the penny dropped did not bite the bullet and reissue new fobs with an "on off" feature. It's not that they they didn't need some better publicity in this keyless vehicle theft issue.
