Windows winding down by themselves?

[Jazzik]

Do you wear (like me) jeans or trousers with a so-called "watch pocket"?

Then try something like this:

Leather, approx. 3 x 6 cm. Fold the leather over the buttons and the key fob sits safely and snugly in that pocket without bothering you.
Not possible to accidentally press the buttons. (Experience: at least 10 years).

[Kremmen]

Surely with that the keys are at 90 degrees to the leather ?

Unless you use a second ring

[Jazzik]

You only need that one ring, it has lots of space to move in the "connection-eye" of the key fob as you want it.
Just try.

Just to balance the books a bit.
In 14 years of various Jazz ownership and keeping my keys as per the attached  photo, I have never had the windows lower by themselves.
Maybe it’s just luck?
Photo deleted for security reasons, but was a bunch of 14 keys plus the car key.

Unlike Kenneve I am not a prison guard but do have quite a few keys on the ring.  In 17 years of Honda owning, I too have never had the windows lower themselves.

This has happened to our Jazz EX just once, we'd been to a garden centre and came out to find all the  windows open. Luckily it was a dry day and the car had only been left for about 30 minutes. I mentioned it to the dealer and they told me about the key command. Since then it's been ok so I think it was the key getting pressed again accidentally.
