Hi, having remote key problems, bought my mk6.5 Fiesta over 2 years ago and all along the remote unlocking has not worked. I tried to reprogram the remote unlocking as showing in the handbook, ignition on/off wait for the beep etc... the key still didn’t work even after a battery replacement, a mechanic friend recommended I try a new key, got one on eBay for £30 with trusted reviews from mk6 owners, I replaced the part of the new key with the remote circuit and buttons to avoid having to program the transponder for the immobiliser as I only have one original key. Still nothing!

Anyone know if there could be a problem with the car?
