lextechrob Posted January 2, 2017 Share Posted January 2, 2017 Hopefully one of your no button keys is registered as a master. If not you will need to buy a used engine ecu with a matching MASTER key, then swap the programming over to your existing keys, and then register them as master's. Lexus previously had a policy ( probably still has) if you lost your masters, they would one time pay for the replacemt ecu under warranty ( regardless age/ miles or original ownership), you just gave the pay the $500 for the two key's. Maybee someone else knows a work around. Quote Link to comment Share on other sites More sharing options...
