Can u post clip how to do that on non chrome key, the black plastic one?

It says 433 is Default right on front of packages 📦. I'm in US I could send you a picture. Whenever I remove it changes to 315. Not sure if it's an import difference but it's the opposite in the States. This is why I was confused watching your video. Clearly it's different per country

Is that the same to change frequency from 433 to 315 🙄..because I drive W220 and their key frequency is 315.. but key fob works on 433

Hello, I bought a car in the USA and I can't register it in Germany because of the key frequency problem, the key has a frequency of 315 mhz and here I need a frequency of 433 mhz, if I remove the key what you did in the video, the frequency changes at 433 mhz, and does it need coding or is it ok, the key works the same as before? thank you very much.

how do you know car need 315 or 433 Mhz? Does MB tells you same as BMW does (when reading immo) ?

You know if this method would work with a Mazda smart key? I bought a 315 MHz key but I need 433
