cduluk Posted March 23, 2011 Share Posted March 23, 2011 Now i could be wrong... but i "think" you need at least one functioning master key to program another one. BUT, i could be wrong. I know this to be true about other Lexus key models. Have you asked your dealer if a new key can be programmed? I don't believe they come from the factory already programmed when you get it, i think the dealer needs to program a new remote by using another working one. And you haven't been able to get in the car since you lost the key? Have you tried calling a towing company or lock-out service? Quote Link to comment Share on other sites More sharing options...
