Thanks Bob...but tell me, if we buy a key from Lexus (which we did for $400+ dollars) and get the new key with ROM for the door opening receiver module, isn't that all that's required? Putting the ROM in the module and the new key with the new ROM correctly installed in the module (89741-5005) should activate the door locks...correct? No further trips or ransom money paid to Lexus to get the remote door function on the key to work. I ask because the remote still doesn't unlock the doors after the new ROM installed. Tested the key transmit on FM 94.9hz...it works! Locked the doors from the interior then put the key in the ignition / removed it then cycled the master lock control on drivers door x10...locks cycled once, automatically, so it's in diagnostic mode. Pressed remote button on key..NOTHING! Stuck the metal part of the key in the module antenna port and pressed remote button on key..NOTHING. So, it looks like the remote transmit function on the key is working...problem isn't the antenna. All that is left is the module itself ...which is a strange coincidence 'cause it worked just fine before we had the local AAA guy break into the car when the key broke and stopped working.....but maybe...maybe that's why we couldn't open the door in the first place...the module stopped (89741-50050) stopped working !!! Hmmmmm. It could be that unless we still need to make a trip to Lexus after getting the new key and ROM installed....do we?
