Key fob goes to sleep.

[old man 2]

 Maybe a bit of useless info, but I've been a bit obsessed with car security since since I bought my last car, a stealable, black Hyundai Tucson.

On that car the the key fobs went to sleep after a few minutes of lack of movement and stopped sending signals to the car, thereby preventing relay theft. I don't know exactly how long it is before the fob goes to sleep, but I left my fob undisturbed for 7 mins which was long enough.

I asked the sales person when I picked up my car on Friday if my fobs did the same, but he didn't know, so today I experimented and the answer is yes yes they do - I'd have been disappointed if they didn't in this day and age.

 Yes I know there's a way to disable keyless entry via the fob and this applies to my car and so I can't speak for other years and models, but I'd like to think that any model coming out of the factory recently will have the same feature.

I don't rely solely on this feature and keep my fobs in a Faraday box and generally use a Stoplock as well, but it's good to know that my fobs have this feature.

 Apologies if the above post is a bit garbled. Not sure if it's my fault or my laptop, however I expect you get the gist.

There wasn't a single date when they changed over to sleeping key fobs, it is model dependent, but it is around 2022/23.

It took them longer than other marquees to make the change.

I tested mine and they slept between 3 and 4 minutes, hence I don't feel the need to have the keys in a pouch.
