🔑 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 Review

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.

To be clear, let me start by saying that this is just a key fob case. It contains no electronics. But that's what I needed. My old key fob worked perfectly except for the spring mechanism, so the key didn't fall out. I was planning to convert the electronics to the new key using a YouTube video.
