VSC lights are also on as well as the CEL.

Did search, thinking it might be a busted ECU. Any ideas?

who reflashed your ECU and why?

locksmith; lost all master keys man when someone broke into home, didn't take the car...

do you mean the key? I think the dealer would probably be able to get you a new master key with your vin number. check with the dealership that does keys for 30 bux or so, they might be able to help you.

sewell lexus can get you a master key pretty easily, just takes a few days. 30 seems low for a dealer. i guess id be concerned too since they have your car keys now, they can take your car when they feel like it.

I wonder if you can go buy used ecu and change the keys transponder. Just change the transponder to correspond to the new engine ecu but keep the cut the same for your doors and ignition. keep the vin number of the car where u got the used ecu.

do you mind if i asked where you got yours done? i live in nyc and only have 1 key which is not a master. how much did it charge? Also, check your fuse that controls the break lights
