Hi to all.
This could be funny but it's real: I lost a keyless inside my Mazda 5.
As you all know, with a keyless system it's not necessary to insert the key in the ignition.
I'm sure the key is inside the car because I can turn it on. But I cannot find the key inside the car.
I was understanding if there is a way to detect the signal this lost key is emitting.

 

It would be much easier to simply thoroughly inspect the Car.

At this point, the next thing I plan to do is remove all seats. I've searched every where.
