Review on 🔑 BINOWEN Mazda 3 Buttons Key Fob Shell Remote Case Replacement with Folding Uncut Blade - Fits Mazda 3 5 6 RX8 CX5 CX7 CX9 Keys - The Best Option by Aaron Jensen

The original metal key doesn't fit this new case, you need to copy/cut the key instead of just replacing the old one, the only thing you can and should do is put a small RFID on Have the end of the key - A chip very well glued into the old key, you need to gently tear open the old key to get the chip. As for the far end of the key fob, I don't need that end, just the key part, but I'll keep it for spares. Also before I forget it doesn't come with a logo to cover the screw although the last picture says it has a logo which doesn't come with it
