  • Key not turning, remote not working
  • All keys disabled after key-data corruption in the processor
  • Board damage alongside the data fault

Repairable?

// Bench verdict

Yes — even with damaged key data. On one SL55 the processor data and board were both damaged: we recovered the original data and programmed it into a second-hand switch, against a dealer quote of over £700 for a new unit.
