Hi all, I would like some help on how to program a used key fob I have just received via Ebay. I have put my original flip key into the ignition gone to II and back to 0 4 times within 6 seconds (as stated in the handbook) but no tone is heard. I have tried this several times, even cutting the time down to less than 3 seconds, but still no tone, so the system has not entered the 'programming mode'. Any ideas on what to try next would be greatly appreciated. The car is a 08 C-max Titanium. Thanks.
