Was the valet key stolen when the car was parked where you frequently park it? If not, the thief might not find your car again. You might be able to have the all the keys "deleted" from the vehicle ECU memory and then have the keys you still have programmed back in. The thief would still be able to unlock and gain access to your car but the stolen valet key could not be used to start the engine. If that is not good enough, yes, you can have the service center replace and program new keys but there will be significant expense to change the door and trunk locks and the ignition switch. Insurance may cover much or all of the cost if you have it.

If it's water and not coolant, I would suspect a blocked A/C drain.

I always think heater core. Does the water have a smell?

I think it is pretty cheap when a corporation such as Toyota stops furnishing repair manuals. Once again big corporations don't care about us little people

A bunch of LX engines prior to 02 had the exhaust manifold problem. It tends to crack in an area that is not easily seen, and it gets worse with age. Lexus replaced the ones that went bad during the warranty period. The replacements do not seem to have the problem. If you find a used one, be wary - it may have the same inherent weakness. Ordering the replacements should give you the updated parts - whether from Toyota or Lexus. If you know of a good mechanic, they can replace the manifolds. I just would not get a used part for fear of getting one of the faulty ones.
