What is this in the back under the mat?

Is this a sensor or something? There seems only two wires go to it, not grounded to the body.
Can it be moved? Can it be turned 90deg? I want to use this space for some storage...
Thank you!

 

In a previous thread, that was identified as a smart key antenna.

Probably need to keep that if you want to get into your car.

 

Thanks!! I had wondered that myself when I added my storage platform. I ended up duct taping it down to the bare metal to protect the electrical connection and add stability before I laid carpet over the top of it. No issues so far with smart key operation.

 

While the vehicle is open, unplug it and see if your smart key still works. If it doesn’t, then plug it back in and share the results. If it does, they share the results and back to the guessing game.

 

It pays to read. This link was posted in the 2nd post in this thread:

(Spoiler alert), it's for an antenna.

 

What the hell is an indoor luggage compartment antenna for? My 2018 TuRD doesn't have one.
