I am having a bad time trying to reprogram the remote entry on the key!!
I have tried all of the following but never no luck i keep getting the lock / unlock twice code was not accepted

Remote (key) Transmitter PROGRAMMING

NOTE: The remote keyless entry system is equipped with 2
transmitters, having 2 unique vehicle access codes programmed
into the wireless door lock ECU.

MODES OF REGISTRATION (PROGRAMMING)

There are 4 registration modes:

Add Mode:
Adds a transmitter without erasing existing transmitter
codes. Four transmitter codes can be registered at one time. If number
of registered codes exceeds 4, previously registered codes are erased
in order, starting with first registered code.

Rewrite Mode:
Erases all previously registered transmitter codes and
reprogram new transmitters.

Confirmation Mode:
Informs user of number of existing transmitter codes already
programmed in system.


Prohibition Mode:
Erases all existing registered transmitter codes and cancels wireless
door lock operation. Use this function if transmitter is lost or stolen.




REGISTRATION OF RECOGNITION CODE

1) To begin programming, remove key from ignition switch.
Ensure driver’s door is open and unlocked, and all other doors are
closed. Insert key into ignition switch, and then remove it. Go to
next step.
2) Complete the following in 40 seconds or less: press door
lock switch to LOCK position, and then within one second, press door
lock switch to UNLOCK position. Repeat procedure continuously until
door locks have been locked and unlocked 5 times. Close, and then open
driver’s door. Go to next step.
3) Complete the foJ4owing in 40 seconds or less: repeat
procedure in step 2), except~ for closing and opening driver’s door.
Insert key into ignition switch. To enter desired mode, turn ignition
switch to ON position and back to LOCK position (one cycle), within
one second, the specified number of times. See REGISTRATION MODE
SELECTION table. Remove key from ignition switch. Go to next step.

REGISTRATION MODE SELECTION

Registration Mode No. Of Ignition Switch Cycles
---------------------------------------
Add 1
Rewrite 2
Confirmation 3
Prohibition 5
---------------------------------------

4) If any mode other than confirmation mode •is selected, go
to next step. If confirmation mode was selected, door locks will cycle
0-4 times depending on how many transmitter codes are stored in ECU.
Example: two stored codes equals 2 door lock/unlock cycles.
Registration of confirmation code is complete after door locks cycle.
5) Complete the following in 40 seconds or less: if add mode,
rewrite mode or prohibition mode is selected, to confirm proper
initiation, door locks will automatically cycle one time for add mode,
2 times for rewrite mode and 5 times for prohibition mode. Press
transmitter LOCK and UNLOCK buttons simultaneously for at least 1.5
seconds, and then within 3 seconds, press any transmitter button for
at least one second. Go to next step.
6) If within 3 seconds, door locks’ cycle one time, new
transmitter code has been successfully accepted. Go to next step. If
door locks cycle 2 times, new transmitter code was not accepted. To
program an additional transmitter or to make a second attempt, return
to step 5) within 40 seconds.
7) Registration of recognition codes is complete under any of
the following conditions: l~

* Forty seconds has elapsed since wireless door lock ECU has
responded.
* Driver’s door is closed.
* Key is inserted in the ignition key cylinder.
* Four recognition codes are registered at one time


To program your remote entry:
Make sure no key in ignition, driver door open and another 3 doors are closed and locked.
Insert the master key into ignition switch then remove it. Lock and unlock driver door 5 times( use the lock and unlock buttom at the door handle, not the master switch).
Then close and open the driver door one time.
Lock and unlock driver door 5 more times (at the door handle, same like the second step).
Then insert the master key in ignition and turn it on and then off. Remove the key. You hear the door lock and unlock itself once.
Then press the lock and unlock bottoms on the key (at the same time) and hold it for about 3 seconds.
Release both bottoms and then just press the unlock bottom for about 3 seconds and you should be done with reprogramming the remote entry.

Using an old key I can program the key so it starts, but have tried over a dozen times and can not get the remote keyless entry to program, the module in the keyless entry is s brand new one less than a month old and is genuine Lexus not some Chinese aftermarket one off eBay cost me $80 Australian, I want to have 2 masters and my valet key just for piece of mind, how do I tell if thew previous owner had the max/too many remotes programmed and how do I fix it?

Thanks in advance.....
