Could someone explain (or link) what exactly is the go with all those crazy costs associated with getting new sets of keys and remotes. More importantly a technical explanation of how the whole system really works.
I've got an idea, but I don't know where it came from. I'll share so as to provide a springboard for replies. /CAR has 'unique' a physical code as well as a digital code. |-ICC contains 5 (or so) memory banks which store REMOTE codes which are authorised to operate vehicle. /KEY has physical code as well as a transponder. |-PHYSICAL code is old fashioned cut similar to pin tumber lock |-TRANSPONDER must be programmed by car to transmit the correct code to unlock the car. (else ignition is disabled although physical entry into vehicle is gained) /REMOTE has unique non-programmable code. How is it different when you only have one key/remote left? The car can be easily programmed to recognise new remotes, regardless of how many you have. Keysmiths can program a new key if you have two Keys, but Ford must do it if you only have one left (Is that right? Why so?) Maybe I should have waited till morning to post. p.s. What does ICC stand for? Integrated Car Computer? |
