Consult your owners manual--in the radio section there is a master code listed---use that then reset the radio with your own code---

Not too bad. Not much room, just enough to drop the starter. It is probably easier to go up through exhaust if you can get your exhaust shield off the manifold .

Unlocking 91 Lexus sterio security code

if you don't have the correct code then you need to take it to Lexus and let them do it. It should only be around 50-100 dollars for unlocking and new code...or just buy a new system
