Yes, you can reprogram it. Just follow the link above.

 

Here are my notes where I successfully programmed a master key for my 1gen a few months ago:

RX300 Master Key Programming Procedure:

March 23, 2010: Successfully programmed new key as per the following

FOR CARS WHERE YOU WANT TO CREATE A SPARE KEY:
Before starting, press and release the Brake and Accelerator pedals at the same time.

1. Place an already programmed Master key in the keyway (Do not turn on)
2. Press the Gas pedal 5 times.
3. Press the Brake pedal 6 times.
4. Pull out the key.
5. Insert the new key but DO NOT turn it on.
6. Press the Gas pedal just 1 time and wait until the security light stops blinking (about 1 minute).
7. Remove the key and press the Brake pedal 1 time. The cycle is now closed.

The programming mode will end after 10 more seconds.

REGISTRATION OF RECOGNITION CODE

1. Open driver door, keep it open and in the unlocked position (all other doors should be closed)
2. Put original key in ignition and pull out
3. Lock and Unlock the doors 5 times (complete each lock/unlock cycle within 1 second and entire process in 40 seconds or less)
4. Close the door and open the door
5. Lock and Unlock the doors another 5 times (complete each lock/unlock cycle within 1 second and entire process in 40 seconds or less)
6. Put the new Master Key in the ignition, turn it to "on" and then off (with 1 second) and remove from the ignition.
7. Press and hold transmitter LOCK and UNLOCK buttons simultaneously for at least 1.5 seconds, and then within 3 seconds; press any transmitter button for at least one second.
8. If within 3 seconds, door locks cycle one time, new transmitter code was accepted. If door locks cycle 2 times, new transmitter code was not accepted. If code was not accepted retry step 8 again.
