I have two remote keys for my 98 S4, however, both keys are in poor condition so im looking to buy new remotes but use my blades.
My fob is 2 button but on ebay they are all 3 buuton with different frequencies.
1) will a 3 button remote work on my S4? (minus the seperate boot unlock)
2) How do i know what frequency my key fob is?
