    Default Smart FourTwo 450 key learning fail...

    I have a problem with key synchronization in a smart FourTwo 450 from 2000. I tried to sync X431 and Fvdi but with no result. I did everything as in the instructions, but the immo light does not flash (when the procedure starts, it should blink quickly). I have two new and two old remote controls. One key is received, but the direction indicators flash quickly 9 times. In Zee, an error occurs that the key is over-role code. Maybe someone had a similar problem. Any other method?

    I've always done coding with Texa and I've never had any problems.

    Have you tested the frequency of the remote control if it is correct?

    I've tried many ways... and still nothing.Maybe it would be better to make a virgin module and enter the keys again?

    I see that this module has already been programmed on the table, there are traces of soldering for the processor

    Why do you want to sync, due the famous X? Did customer have 2 keys? If you can not sync it is very well possible that the key is the issue. Keys cost close to nothing so maybe programming a new one is simple test?
