Hi guys I hope you can help me.

Whilst searching throughEbay I came across this.

I was wondering if this would work with my 04 Zaf GSI as I know it differs slightly from my current one with 2 buttons. (the third on this one being the boot clip)

Does anyone know if the wiring is in place in the car already to accept this type of fob or is it just not worth the hassle.
