We just acquired a like-new 2003 LS430, after loving the 1992 LS400 we owned for 131,000 problem-free miles. However, I would appreciate knowing the factory's "secret" programming steps, or at least as many of them as possible. For example; we did not know, until my wife had her keys accidentally locked inside, that closing the trunk automatically locked the car doors! So the dealer re-programmed it for us so it waits a minute before doing that. Great, but I don't want to have to drive 30
