I don't know is it Ok in US to pay $400 for some cheap radioelectronic parts replacement or not. But I think it's too much.There are over a dozen places online that say they will rebuild your ECM like AES provides ECU ECM TCM PCM BCM Control Modules Automotive Electionic Solutions Main and ECU/ECM/TCM/BCM/ICM Rebuilding Service and Auto Computer Systems - quality auto ecu, tcu, & ebcm units,engine control units/modules/computers(ECU,ECM,ECC) & transmission control units(TCU,TCM,TCC to name a few. They say they can rebuild it for about $400. Has anyone tried that? It would sure save the cost and hassle of dealer key reprogramming if the original code was retained.
I had transistor replacement in KESSY unit free of charge in Russia (but because techincian did not repair the main problem) and now I dont have annoing "Key not found" warning. I know a story that one guy in Estonia had the dead KESSY unit repaired for $60 (two transistors and two resistors replacement). But the car prices in US much more adequate then in Russia (almost two times less), so that repairement costs looks not so terrible.
