Yaris Verso 2001 - Key Guidance

[Quincy]

Hello All,

I drive a Toyota Yaris Verso 2001. My key fob has cracked and now the metal bit of the key is very weak and flimsy. Is there a way that I can replace the key fob and not anything else? My key is 10mm wide. If possible, could I get a link to somewhere which sells one just like mine. I have also attached a photo of my key

Also, if I were to get a key, will it work with my car with Toyota Security system?

Thanks in Advance
