I word of advice. Change the water pump when you change the timing belt (and visa versa). The additional labor cost should be minimal you might as well get it over with because it will eventually need to be changed and the labor coast will be much higher.

I was told by a Lexus Service Consultant that the transponder ignition key programming for a 2004 ES 330 and a 2005 ES 330 was not the same as previous years. Thanks to you folks, I copied the previous years transponder key programming from this site. Can anyone tell me if the transponder key programming has changed in 2004 and 2005. Thanks for your help.
