Hi There i have a 2000 mk1 focus zetec, we recently lost our remote key somewhere so we had to call out a locksmith! after spending loads of money we now have 2 new keys, 1 remote and one standard! Last week we found the lost key so i decided to reprogramme it and put it to use! i put a new battery in it first and then did the 1st key, 2nd key, 3rd key trick which worked, so i now i have 3 working keys woohoo! the problem is when i tried to programme the key to be able to use the remote locking it worked but then the 1st key stopped working?? so i reprogrammed the 1st key and it worked and then the 2nd key stopped working??? basically i cant get both remote keys to work at the same time (not literally the same time, you know what i mean). Im stumped can anyone please help :)
