Keysy Rewritable RFID Key Fobs (5-Pack, Black)

Verificar antes de comprar, es costoso y puede ser una pésima compra.

Love it. Works great!

it works as advertised. Very Happy with the Product.

Worked as advertised

Work great to copy 125mhz card keys using the keysy

Copies key tags flawlessly. Cards are more difficult.

Used these for my apartment! Great to have extra and easy to set up!

Product exactly as described, easy to use. Can highly recommend.

The key fobs are very easy and convenient to use and I discovered that if you take them apart the active element is a disc about the size of a nickel and about as thick as a credit card. I removed it and put it in my phone case so now my phone opens doors.

Very good
