Fantastic. Waited less than a minute for the Code and it works.

I had an old 80's Ford Stereo that had been sat unused in the garage for 15 years. Managed to power it up but code locked out. Googled these guys but was very sceptical. Ford forums had used them before and were genuine. I entered the serial number and the code came back instantly. Put it in the car and boom it worked. Couldn't believe it and it only cost a fiver.

Easy to use quick and simple took 30 seconds and I was in highly recommend!
