You will probably need a bypass module, too. The Fortin Key-OverRide-All is a good module and readily available for about $35.
Here is a link to the install guide : http://fortin.ca/download/699/key-override-all_lexus_rx300_(1999).rev-a.pdf

Thank you for the links. I guess what threw me off was the manual says its for a CM800s and my unit says its a CS800s.

Gotta luv Compustar.  They are referred to as CM800-s and CS800-s pretty much interchangeably.  Then there is the 6000 series ( where they use FT, also ) and the 600 series plus all the Remote Kits...

I've been downloading their catalogs (you know why) and I'm soooo confused. remote start / stop, 99 lexus rx300 - Page 2 -- posted image.
You know why.
Can't wait to play with the real thing though.

I kinda think maybe they call the control unit a CM800s which is used in the CS800s which is basically an installation kit.

I think i will give up a key instead of buying a bypass unit and the extra work. I only need one key anyway.

Your choice.  For liability reasons, I always go with a data style bypass module.

You could buy a new un-cut transponder key off EBay for $8 and use this method to program it to the car.

Lexus 1999-2003 RX 300 Key Programming - For NEW UNCUT KEYS

 Process works with all keys - remotes, valet, non-remotes

1. Enter the car with a working pre-programmed key and close all doors. Simultaneously depress and release both

    the brake and the accelerator pedals.
2. Within 5 seconds, insert the working pre-programmed key into the ignition. DO NOT TURN THE KEY.
3. Within 15 seconds of inserting the ignition key, depress and release the accelerator pedal 5 times.
4. Within 20 seconds, depress and release the brake pedal 6 times.
5  Within 10 seconds, remove the working pre-programed key from the ignition.
6. Within 10 seconds, completely cover the remote head off the pre-programmed key with aluminum foil, hold the
    head of the new unprogrammed and uncut key next to the pre-progammed key head and insert the pre-
    programmed key back into the ignition.
7. Depress and release the accelerator pedal one time. The security light should now begin flashing to indicate that
    the computer is reading the new key and programming the system.
8. Leave the pre-programmed key in the ignition for at least 60 seconds with the new unprogrammed key head still
    next to this covered pre-programmed key head. When the security light stops flashing, the programming process
    should be complete.
9. Test the new, uncut key. Place the pre-programmed key (still covered with the aluminum foil) into the ignition and
    verify that the SUV will not start since the transponder signal cannot be read. Remove the key and place the newly
    programmed uncut key next to the covered pre-programmed key head and insert the cut key into the ignition again.
   Turn the key and see if the SUV starts. If it does the new uncut key has been successfully programmed into the
    vehicle's electronics.

This way you still have two working keys and the key hidden in the car and used with the remote start can't be found

by a thief and used to steal your car.  Of course, $8 for the key and $15 for the "key-in-the-box" universal bypass
module isn't that much less than a data style bypass module, which are more reliable in cold climates.

Soldering is fun!

Thank you for being so helpful. It's refreshing to see so many helpful members. Question, If i just use my spare key, do i still need this ... "key-in-the-box" universal bypass module ? I don't know what that is.
