Just called Lexus and they told me that the key with the wrong code will be able to unlock the door, but will not deactivate the alarm. Of course, the key will not be able to start the ignition either.

JAMES2210 brings up a good point. I think we all agree that a key with the wrong code will not start the ignition. But will this key with the wrong code be able to open the door?

Hi everyone, Took my '03 LS430 to the dealer yesterday for some warranty work. When I went to pickup the car in the afternoon, I was shocked when the service adviser told me that they've lost my key! This is the key with the smaller head without the remote control. They were somewhat apologitic, and offered to order another key for me. After calming down for a few minutes, I begin to think: what if someone at the dealer has the key? Not only that, that person can probably get my home address and just come over and drive the car away from my driveway without me knowing it. At this point I didn't think the dealership's offer to simply replace the key was acceptable. I then asked to have them replace the entire lock/key system, which I know is VERY expensive. They came back with another offer: they will reprogram the keys and the lock system for us. The question for the forum is: is this a reasonable "compromise"? With doing this also "invalid" the lost key? In another word, the person who has the lost key should NOT be able to unlock the door and start the engine after the key system has been reprogrammed, correct? Any info. you can offer is much appreciated.
