Hello, I recently picked up a 1995 Platnium SC300. I purchased a new one-button master key exact same one as my original (89742-24070) . I can't get my car to actually get into the key fob registration mode (The self lock confirmation after finishing the procedure.) I get to step 6 and nothing happens, I've done it multiple times and get nowhere. Is there an additional procedure available online or do you have any tips and tricks on how to do it? My original master key's button is broken completely so I have no real confirmation that the alarm system actually works or ways to test it. Any help or guidance will definitely be appreciated before I destroy my door panels opening and closing the door.

Here are the steps I followed below

​​​​​​KEY REGISTRATION (1995 AND LATER MODELS):
Set initial conditions:

• Key out of ignition
• Driver’s door open and unlocked
• All other doors closed and locked

Registration Procedure:
NOTE: Perform all steps with no more than a five second interval between steps.
1. Insert key into ignition for 1 second and remove.
2. Cycle (lock and unlock = 1 cycle) the driver’s interior power door lock switch 5 times
(1 second in each position).
3. Close and reopen driver’s door.
4. Cycle the driver’s interior power door lock switch 5 times (1 second in each position).
5. Insert key into ignition and cycle the ignition on and off:

• One time to add a new code.
• Two times to add a new code and erase all previously stored codes.
• Three times to check how many codes are currently registered.

6. Remove key from ignition. Receiver should respond by cycling the door locks a corresponding
number of times:

• One time to add a new code.
• Two times to add a new code and erase all previously stored codes.
• One to four times (slowly) to indicate how many codes are registered (end).

NOTE: If no response is given, start over at the beginning of this procedure.
7. Press the transmitter button (any button on fob type transmitters) for 1 second.
NOTE: Receiver should respond by cycling door locks once. If no response is given, start over at the
beginning of this procedure.
8. Close and reopen driver’s door.
9. Press the transmitter button for 1 second. The receiver should respond by cycling door locks:

• One time to confirm operation is complete.
• Two times to signal that the code is already registered.
