Default for all u techs heres a question

today had a 04 ls430.
the master key fob trunk release button was inop. other key works
replaced the smart key
i then programed the imobolizer
now the car starts
when i tried to program the key fob i couldnt find how to do it on tis

1 tech said there is a button near the tire pressure sensor. press and hold wait for the green light.
that didnt work

another tech said try programing it like
insert key and remove key 2 times then open door 2 times sequence. that didnt work

another tech said to do the other sequence. that didnt work

now i got fed up going arround asking everyone how to program it. i went to a ds. to my surprise he couldnt find it on the diag tester or trying any of the sequences. so heres my question to the techs that visit this place

how do you program the 04 ls 430 smart key fob so you can lock/unlock the car?

Can you give me a run down on what screens you are getting on your scanner? (screen shots or pix would be helpful) What scanner are you using?

Here is the procedure for the 2004 LS without the smart key system.

What is the 8th option down when you are in OBD/MOBD?

Take care,

Tami

So you need a scanner to program a new master remote smartkey?

Anyone programmed a smart key for the '04-'06 LS?

This never got answered. Anyone out there know? There's some smart keys starting at $39.99 on eBay.
