Ford radio locked?
Try to avoid entering incorrect code repeatedly, you can risk blocking your radio permanently!
If the message LOCKED10/LOCK10 appears on the screen, it means that a wrong code has been entered 10 times. At this stage it can still be decoded, but the cassette player only accepts 3 more codes before being permanently blocked. To reset this status, with the radio switched off, press and hold button 6 while turning it on.
If the message LOCKED13/LOCK13 appears on the display, it means that the wrong codes have been tried 13 times, a situation in which the ford's radio can no longer be decoded online, but only by an electronics specialist.
