TOYOTA – LEXUS “PEDAL DANCE” PROGRAMMING PROCEDURES

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


If you have only a VALET key or an unrecognized key then the ECM will have to be reprogrammed or “flashed” before you are able to add any more keys to the vehicle.

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.

Everything else on the internet failed (including the procedure posted above), but this procedure worked for me on my 2006 RX330:

Programming chip key for 2004 rx 330
 

I have tried the instruction on the site to program my key but have been unsuccessful. Are there any other methods of programming the key?

My 2005 rx330 came with only 1 key. So I have been thru this.

There are 2 components to programming the key:
1) programming it to lock/unlock and the rear liftgate
2) programming the key so the engine will start (transponder-ecu)

I only had luck with a genuine lexus transponder (and key), got it on fleabay from a lexus dealer. I then got the key cut, and then programmed the the lock/unlock and rear liftgate. The key would turn but not start the car. nada. nothing. the engine didn't turn over.

Then some where on the forum I found a post with this:


$15. since I had 1 key already, I could use this gadget, and it was programmed in less than a minute (the second key). very easy.

I would send you mine, but it would probably be cheaper for you if you ordered it direct if you have amazon prime.

Hope that helps.
