The listing, 2010 Mazda 4-Button Switchblade Flip Key has ended.
Here is a OEM switchblade flip key from a 2010 Mazda 3S (FCC ID# BGBX1T478SKE12501SKE125-01). Its in brand new condition, I got it when the vehicle was brand new and never used it. The Key is still in it, if you need only the remote portion you can easily install your key and program to your vehicle. If you need the key itself, you will need to buy an uncut replacement. I do not know exactly what models it is compatible with, please research to ensure compatibility
