lsrxlex Posted October 12, 2014 Share Posted October 12, 2014 My ECU needs to be replaced because the AC Compressor doesn't work, everything else works fine. Lexus said I need another ECU. I plan to buy a used one from eBay with the same part #. My question is how to reflash it to make it work with my current keys. Do I have to drive to a local locksmith then replace with the newly bought ECU. Then have the locksmith do the re-flashing? Quote Link to comment Share on other sites More sharing options...
