Default Programming 2008 RX350 Remote

I've been reading all the forums about programming the key fob remote (both the immobilizer and keyless entry components). I've followed the instructions below without success:
TO PROGRAM IMMOBILIZER

1. Enter the car with a working pre-programmed key and close all doors.
2. Simultaneously depress and release both the brake and the accelerator pedals.
3. Within 5 seconds, insert the working pre-programmed key into the ignition. turn key to on but do not crank engine.
4. Within 15 seconds of inserting the ignition key, depress and release the accelerator pedal 5 times.
5. Within 20 seconds, depress and release the brake pedal 6 times.
6. Within 10 seconds, remove the working pre-programmed key from the ignition.
7. Within 10 seconds, insert the newly cut transponder key into the ignition. Turn key to on but do not crank engine.
8. 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.
9. Leave the new key in the ignition for at least 60 seconds. When the security light stops flashing, the programming process should be complete
10. Start the vehicle using the new key to verify that programming was successful.

The security light on my car continues to flash after serveral minutes without going off and the car will not start.

TO PROGRAM REMOTE:

1. In drivers seat WITH DOOR OPEN, start with door unlocked.
2. Put master key in ignition, turn to on, then back off and remove.
3. Using the lock/unlock button on drivers door. press the lock/unlock combination 5 times. (lock, unlock, lock, unlock, lock, unlock, lock, unlock, lock, unlock)
4. Close driver’s door, open driver’s door.
5. Perform lock/unlock procedure again. DO NOT close and open driver’s door. Just the lock/unlock procedure again.
6. Insert NEW key in to ignition and turn to on, then back off and remove.(at this point the doors should lock and unlock by themselves ONCE)
7. Now press both lock and unlock buttons on REMOTE. release after about 1.5seconds. now press just the lock button on remote. once you press the lock button, the car should lock and unlock ONCE, if it lock unlocked TWICE you messed up somewhere.
8. Open and close the drivers door a couple times to close programming. if you did it right, remote will now work.

I've also followed the attachment I've found in another forum for the remote.

Can anyone tell me what I'm doing wrong? Is there a specific technique to programming to completing the immobilizer (ie: push down the gas peddle right to the floor, applying it for one second, etc).

The dealer wants $100 to complete this. I would love to save the money for something that appears to be easy to do. Thanks to all in advance for your help.

Default Programming the Garage Door Openers

This is a slightly different subject but may be of use to someone.

If you use the Lexus 2008 RX-350 manual and try to program a Chamberlain "Rolling Code" garage door opener, you may have trouble. I recommend you go to www.homelink.com and use the directions they provide.
My experience (after 2 hours of fruitless attempts to program the code by using the Lexus manual) was that 2 important steps are not included in the manual.

Thanks for your reply, but I am looking to program a new key, not my garage door opener. I have read on a few sites that post 2007 models can only be programmed through the dealer - is that why the instructions I've posted are not working?

According to a website that sells lexus keys, 2007 - 2009 requires the dealership to program the keys (ie: the methods I've shown on this post will not work). Can anyone confirm this?

Thanks!

The immobilizer can only be programmed using a device that plugs into the vehicle. Many locksmiths have these devices and charge less than Lexus.

I am still trying to figure out how to program the keyless entry buttons.

Default 2008 RX350 FOB Programming

I really wished this thread did not just end abuptly. Did anyone ever find the programming instructions for the 2008 RX350 FOB? I had a 2006 RX330 and did the door open/close dance and was able to program the keyless entry. i purchased a copy of techstream and was able to program the immobilizer. I sold sold my RX330 and purchased a 2008 RX350. Now I needed to program a new key. Again i used my techstream and programmed a new key to the immobilizer. However, the door open/close dance does not work so i cannot program the keyless entry. i've looked everywhere for a possible updated dance sequence to try. I did find a different sequence but that didn't work either. I will try to post it. maybe i will try again with my techstream to see if there is a new feature to program the keyless entry. Again, did anyone else have any luck programming the keyless entry on their RX350?

What door steps did you follow? The actual opening and closing of the door or the door locks? Can you provide the exact steps? I have a 2007 rx350 that I hope it works on.
