This is known to work for 98-02 LC/LX and possibly 05-07. 03/04 supposedly have a different transponder chip in the key which requires dealer programming. Heavy YMMV on all of this with model year differences and numerous different sequences floating around out there.

Of primary importance is determining if you have a key that is enrolled in the car’s computer as a “master” key or a “valet” key. The procedure for making this determination is:
1. Positively locate the “security” or “anti-theft” light. This light should blink when there is no key in the ignition or if an unrecognized key is placed into the ignition.
2. Insert the key you have into the ignition – DO NOT TURN ON.
There are 3 possible things that may occur:
(a) Security light continues to blink = unrecognized key.
(b) Security light goes off IMMEDIATELY = MASTER key
(c) Security light remains illuminated for 1-3 seconds before going out = VALET key
A master key allows you to program more keys. A valet key cannot enter the programming sequence, so it can only start the car. If you find from the above that you have only a valet key, you can try having your ECU flashed (contact info in pdf link).
Once you have determined that you have an enrolled MASTER key you may proceed to either:
(a) delete all other keys from the car’s computer
(b) add an additional MASTER key to the car’s computer.
(c) add an additional VALET key to the car’s computer.
