97 LS400 will NOT enter programming mode?
UPDATE: I disconnected the battery and waited 20 minutes before reconnecting the battery to clear any type of lock out code..? I am now able to access the programming mode. I used the manual lock/unlock switch on the drivers side door. After step 8. (the auto lock/unlock cycle) I hear a beep and then a quick double beep? Still no response from the key fob in programming it?
1. sitting in driver seat, with driver's door OPEN, press lock/unlock button ON THE DRIVERS DOOR to lock all doors, then manually unlock driver door only.
2. Insert YOUR key in ignition, DO NOT TURN, then remove key.
3. Using the same lock/unlock button ON THE DRIVERS DOOR, slowly press lock-unlock in 5 cycles
4. Shut door.
5. Open door.
6. Using the same lock/unlock button ON THE DRIVERS DOOR, again slowly press lock-unlock in 5 cycles
7. With the door open insert your key into the ignition, turn to 'on' position (DON'T START), wait 5 seconds. Turn off and remove key.
8. Locks should cycle once (Car will lock and then unlock once by herself). If they don't cycle or they cycle more than once, do steps 1-7 over.
9. Now using the remote, push lock button, hold for one second, then release the button. The locks should cycle once. If not, start over and go slower.
10. Close the door.
11. Open the door.
12. Press the lock button on the remote. The locks should do a lock-unlock cycle.
13. Close the door
14. Press the lock button on the remote, the doors should lock.
15. Press unlock button and the doors should unlock.
My 97 LS400 will NOT enter programming mode so I can program my used remote. I have replaced the passenger front door actuator and Lock/Unlock switch on the same door that was not working. Now all the doors will cycle the lock and unlock series but the car still does NOT enter programming mode??? Any suggestions are appreciated. Thanks, GPappy

I have already been to the local dealer. They charged me $45.00 to cut a new Lexus key for me. Very fair price I thought. However, the service manager told me that it was only a key to unlock my doors and would not start my car. They told me because the passenger side door lock actuator was not working they could not program the key to start the car and they could not program my remote FOB. I tried the key yesterday and it starts my car just fine. LOL, go figure.

This procedure worked for my MKIII / '97 / UK-model.
Procedure:
Registration - FOB:
1. sitting in driver seat, with driver's door OPEN, press lock/unlock button ON THE DRIVERS DOOR to lock all doors, then manually unlock driver door only.
2. Insert YOUR key in ignition, DO NOT TURN, then remove key.
3. Using the same lock/unlock button ON THE DRIVERS DOOR, slowly press lock-unlock in 5 cycles
4. Shut door.
5. Open door.
6. Using the same lock/unlock button ON THE DRIVERS DOOR, again slowly press lock-unlock in 5 cycles
7. With the door open insert your key into the ignition, turn to 'on' position (DON'T START), wait 2 seconds. Turn off and remove key.
A. turn to 'on' position 1 time is the “Add” mode. This is used only on some models and it allows you to add a remote to the already existing remotes.
The ECU confirms this by locking and unlocking the door locks automatically after you remove the key.
B. turn to 'on' position 2 times is the second mode which will erase all previously programmed remotes and allow you to program new ones.
The ECU confirms this mode by locking and unlocking the door locks twice after you remove the key
C. turn to 'on' position 3 times is the third mode which tells you how many remotes are already programmed to the ECU.
It confirms this locking and unlocking the door locks the amount of times applicable to the remotes coded.
If no remotes are programmed then the ECU locks and unlocks the door locks 5 times.
The ECU will hold up to 4 remotes at any one time.
8. Locks should cycle once (Car will lock and then unlock once by herself). If they don't cycle or they cycle more than once, do steps 1-7 over.
9. Now using the remote, push lock button, hold for one second, then release the button. The locks should cycle once. If not, start over and go slower.
10. Close the door.
11. Open the door.
12. Press the lock button on the remote. The locks should do a lock-unlock cycle.
13. Close the door
14. Press the lock button on the remote, the doors should lock.
15. Press unlock button and the doors should unlock.
before it gets successfully programmed, you may hear a 10-second long beep.
Procedure:

I am now able to enter the vehicle's programming mode. However, the new/used key FOB does not seem to be communicating with the vehicle. I will take it to the key shop and have it tested Monday. Yes, I have already tested the FOB battery and it is showing 3.8 v. I just don't know if it is transmitting any signal.? My FOB FCC ID is HYQ1512P. I have also seen online the required FCC ID is supposed to be HYQWDT-C.? Any input on this?

I had the same problem with my car(1996). It's frustrating and I finally gave up and took it to a Toyota dealership thinking they might have a machine that could bypass what I was doing. No go, that had it for several hours then told me it could be multiple door actuators that were causing it not to go into programming mode(but they weren't specific). Let me know if you find a way(and what caused it) to get it into programming mode. I have two remotes that are just sitting there.
Thanks again to all that helped with input. RA40, plexus914, PureDrifter,
I finally received a fob with the correct FCC: HYQWDT-C. The correct FCC: number is clearly listed in the owner's manual BTW. Utilizing the drivers door manual lock/unlock switch to enter the vehicle programming mode worked perfectly the first time. (NOT the switch that locks and unlocks ALL the doors).
