focus key

[xgrig]

hey guys
Just purchased a 2008 LT Focus Tdci and am looking to get a second flip key
already have the original flip key and a spare normal key
anyone know what transponder the LT focus keys use?
been told it's a 4D63 transponder but just want to confirm with someone that would know as i don't want to go forking out the money and then it doesnt work :(

thanks guys
Dave
