I just received in the mail the Lexus remote key FOB I won from ebay for $25.00 including shipping. :) Not too bad of a price considering how much the Lexus dealer would charge (Think it's about $100 maybe).

After search the post for the programming instructions. I attempted to give it a try but realized the I could not find the ECU unit :doh: Check the instructions again and their are no mentions of where the ECU unit is located in the instructions.

So if any one who has programmed a new key remote for their LX450, please let me know where this ECU is located.

Thanks in advance. :beer: :beer:
 
The alarm ECU is under the driver's seat. FWIW I bought a spare remote from eBay for $9 . It was mislabeled as a LX470 remote and no one bid on it :)
 
Thanks for the help guys, I will check it out when I get home tonight.

While under the drivers seat would I have to remove any upholstery or covers to get to the ECU?

No you dont have to, just open up your DS door and you can see the black box.
Actually this is not good for all of the LX owners :frown: just let the (Thief) know where the BOX locate...lol :censor: :flipoff2:

Click here to go to the RS3000 Owners Guide pdf on Beowulf's website. This is also valuable to have for changing any of the setup options such as passive arming, disabling automatic locking/unlocking, etc. On page 23 of 27 pages, you will find the step by step instructions on how to program your new remote. As others have said, the box is usually under the drivers seat. The button that you need to push will be down below the power seat controls. Open the drivers door, stand outside the vehicle, and look under the seat below those controls. You can't miss it. The procedure is very easy. By the way, if you own another Toyota or Lexus vehicle with remote entry that uses the same button to lock/unlock it will most likely work also. My LX only came with one remote, and I was going to buy a second one until I learned this. Now I can open the truck with one button and the car with the other button. Saved money and keeps the keyring smaller too.
 
I also need to setup a new remote that I purchased through the internet. I found the security unit under the driver seat and found
the small green button. Following the instructions that I found on here, I put the master key to "ON" position, pushed the green button
and held it for a long time, perhaps 20 seconds. I looked for an indicator light in the instrument panel as the instructions said, but nothing came on, and I was not able to move to the next step. So, my question is where is the indicator LED that I should be looking for, on the instrument panel, near the speedometer, or someplace else?
 
Which FOB did you buy for your lx450? I lost mine a while ago and need to order another one.
 
I haven't bought one yet, I was looking for programming instructions and stumbled across this thread. I updated the link to the doc that had expired.

That being said, i see several generic rs3000 remotes for sale around $50 on ebay and elsewhere.
