I've ordered a 2nd masterkey off of eBay but the instructions I downloaded off of the internet don't seem to work. I'm getting frustrated w/ the whole deal because I had lots of problems getting the key cut in the first place because my used 2001 IS 300 had the ignition switch changed so it has a new key code different from the original one that's matched to the VIN. Either way, the key opens the door and is cut right but I cannot get the thing programmed. HELP!!!

To program the remotes on your new key, you have to go through the door lock exercise using the old programmed key. I spent a lot of time trying to program using the new key and found out that the old key needs to be used when you do the door lock/unlock routine.

I was successful over the weekend programming a new key for a 2002 Lexus ES300 using the "pedal dance" method. The "door" method did not work. Also, to program the remote, FCC ID#HYQ1512V, the correct method is to do the following with the new key:
1.with no key in the ignition an dthe drivers door open and unlocked
2.within 4-5 seconds put the key in the ignition and remove 2 times
3.close the drivers door and open 2 times
4.put the key in the ignition and remove
5.close the drivers door and open 2 times
6.put the key in the ignition and close the drivers door
7.turn the ignition to ON for 1 second then turn OFF
8.remove the key from the ignition
9.the power locks should now cycle once
10.press the unlock and lock buttons at the same time for 1 second and then quickly press the unlock and lock buttons for 1 second again
11.if the remote is programmed the door locks will cycle once. If failed the door locks will cycle 2 times
12.open the drivers door to end the procedure!

After trying all the other procedures I found, like power lock switch 5 times, or manual door lock switch 5 times, etc....I found the procedure listed above and it is correct. I programmed the new remote in under 5 minutes!....good luck!
