Review on 🔑 Set of 2 Flip Key Fob Remotes, Compatible with Mazda 6 2005-2008 (KPU41788) by Committed Schmidt

I ordered this replacement key fob and tried programming it several times on our 2011 Mazda CX-7 but it did not program. So I opened the tag to make sure the battery was good and found there was no transponder inside. It had a battery and an LED that lit up when you pressed a button, but no other electronics. In the photo, my original has been opened up for comparison (bottom keychain) and you can see that the new keychain (top keychain) is designed for nothing other than LED lighting.
