I never got a key fob when I bought my 350, just 1 key without buttons. Read online that you can program any fob to work so bought one off Ebay to try out. Used the guide on here to try and managed to get into programming mode (heard the two clicks) held the unlock and pressed the lock 3 times & nothing happened, no clicks to confirm and when i take the key out the fob doesn't work. Can anyone confirm if they've use an successfully programmed an aftermarket fob?
