Lost my keys this morning immediately after unlocking the car

[Bretrick]

Searched everywhere for at least 20 minutes.
Where could they have gone? Unlocked the car, put stuff in the back, no keys.
Totally flabbergasted. Searched in the car, searched under the car, not on the roof.
Went inside to get a torch as it was gloomy, (had spare house keys hidden outside), re-searched again.
I give up.
Found them in my back pocket with my wallet.

Oh good, that's a happy ending.

Been there. Vast sand dune field involved as well.

After much sweating, marching back and forth, poking around retracing steps... keys were on the seat of the truck.

Found them in my back pocket with my wallet.

You never lost them (you only thought you lost them).

You never lost them (you only thought you lost them).

Correct. Though for those 20 minutes I thought I had lost them.
I had given up finding them and was on my way to going inside, resigned to the fact that the keys had disappeared.
It was then I tapped my back pocket.

They make key finder key rings now. Here's a couple of choices.

Now that I have just discovered these I want some for myself.
