You can probably find a solution if you got to the RX part of clublexus.com. This is the SC part.

I guess I will try the instructions listed and see if that will fix it.

Thank you
Hmm! If you hear the beep when you hold the memory button and the set button simultaneously, that means the ECU working properly. Try to move your seat to different position then push the memory button to see if the seat moves back. At last, reset the memory using the procedure above.

Default The seat won't move backward when pulling out the key

Hi, Thanks for the tip. All my memory buttons are fully functional. But I have another question. If my memory serves right, when I pulled out the key, the handle used to go up and the seat used to move backward for easy exit from the car. But now the handle goes up but the seat won't move backward. What did I miss?

Handle? Do you mean the steering column? When you remove the key, the steering will retract and tilt up. This function can be turned off using TechStream. The seat will remain where it is. I don’t think the SC is designed for the seat to move back.

GmanSC you are right, the SC does not have the auto retract on the seats, we wish!

This sounds like the problem which occurs after power has been disconnected. The seats have to be "re-taught" their limits before the memory will work.

You should check your manual because I think different years have different procedures. Here's a couple posts from another thread:

What you have to do is move the seat back all the way forward using the power seat back switch until you hear a beep , then move the seat cushion back the entire way again using the power seat control, next move the seat cushion all the way forward using the power control. You can now put the seat in the position you desire and push set and #1.

1. Move the seat forward until you hear a beep.
2. Move the seat all the way back.
3. Move the seatback angle switch forward until you hear a beep
4. Move the seat back angle switch all the way reclined.
5. Set the memory now.
After working on my car for so long and disconnecting the battery I would always be stumped why the memory seats would not work.

Found this post and voila!

Applied this process and it worked like a charm!!!!!!

Thanks!!!!

Now you can program the seats to be in your preferred position.

I tried the above without disconnecting the battery and it did not work. Then I tried it by disconnecting the battery and it worked like a charm. Thanks to all who have posted on the topic, it gave me the nudge I needed to find a solution to my "broken seat memory" issues.
This worked for me today on a 2005

I have a 2005 in order to set your seat memory you have to turn the key on move the driver seat forward as far as it will go till you hear a beep, then move the seat Rearwood till you hear a beep, then move the seat back as far as it will go, and then move it forward as far as it will go. I’m talking about the button that allows you to change the seat then you should be able to program the seats

Thanks for putting this thread together. Just got a 2005 sc430 with 35,000 miles. Dealer had replaced the dead battery with a new one. Guessing that is why the buttons stopped working. Followed the steps and can happily report that they now are working! Hope all my problems are resolved so easily as this one was.
