I lost the two key the master key and valet. :(

i called the dealer. and say that i need buy 2 key and i give a free ecu.

only i need pay for work..

1000 usd for cut and labor for ECU:pissed::pissed:.

because is300 2001 need replace ecm.

________________________________________________________________

i think that is time to start to new proyect and not deal with dealear..

for me is easy buy a used ecm of is300 2002 - 2005 with igniter and key in ebay 200 $ only i need replace ecm 2001 for ecm 2002+.

but here is the part more hard the conversion is

the wire of the engine bay.

is300 2001 is diferent to 2002.

but whats is diferent pin out?.


the ideal work is using 2001 wire harness into conversion, only splicing wire.

i beleave that is possible.

any people try this crazy?

note: trac ecu is necesary replace..

This is all unnecessary. It is true that in the past, 2001 ECU couldn't be flash to accept new master keys (and you would need a new ECU), however recently others have found locksmiths that can indeed reflash 2001 ECU to accept new master key. I suggest you do a search using the custom google search button on top. This is well documented.
