Ls430 2002 Ecu Reflash

[Frostyboy123]

Can anyone advise me of a company , in it around manchester , that can reflash my ecu on my 2002 ls430 and programme a new key. It's fit the usual smart entry start system.

If you know who can do it, or if it's you personally please let me know as I have no keys at all, just a key to manually open it that I had cut as an emergency get In.

I am losing the will to live here, as lexus said they don't reflash them and told me £2000

Cheers team , any advice would be great

i came across a chap on here that siad if have a spare key from anothor lexus and put the electronic part onto or beside your spare key the ecu will reprograme the key , reconds he has done this, so a scrap yard for spare keys .ps there is also a usa company that makes them from chasis no.i will try and find the site .

Yeah the problem is I have no chipped keys just a basic mechanical key to enter the car all the chipped programmed keys have been lost

Thsts what i am saying get a chiped key from anther 430 (breakers / friend ) hold beside unchiped key put into ignition and the ecu should reprograme that chip , i have to try it my self as i have two none chiped keys the open and start the car but no elec open and shut.

But surely if you got a secondhand key that means you could break into any lexus and start it, the non chip metal key won't go into the ignition as its only for a smart key, ie no elongated slit for the key to go into to turn the ignition ?

I am only going buy what i was told havent tried it yet .

You can programme the open and close of the doors by brake pedal and acell pedal pressing and opening doors or something..... There's a post on here for it mate somewhere with full instructions on how to do it ....
