Can someone help identify this black strip stuck to the inside of the windshield of my Tacoma?

I was wondering what this black square was on the inside of the windshield of my 2016 Tacoma DCSB 4x4 Sport? I've not seen anything like it on any 2016 Tacoma I've seen. It's mounted to the left upper part of the windshield on the inside. It's about 3 inches long and 1 inch wide and appears to made of plastic or vinyl. I was gonna take it off but I'm not sure exactly what it is. Can anyone help with identifying it for me?

 

Is it black on both sides? I'd bet its a passive RF tag of some kind. Shine a light through it and post pics.

 

I bet the dealer knows and can tell you over the phone.

Yep, it was either that or it opened gate at the dealer

 

Thanks for the help guys.

 

Immobilizer. For sure.

 

If your penis is not at least that long you cannot drive it

 

Can I get a smaller sticker?

 

Lol. You never disappoint.

 

I think I'll scrape it off first chance I get, then if the truck stops running we'll have a rock solid answer.

 

Definitely an RF tag. Mine had the same from a SE Toyota Dealer. I removed it after a couple days. Didn't leave any residue that some cleaner couldn't take care of.
