Lost key VSC, ABS and (!) on after locksmith and Toyota

I have a 2008 Gen II I-Tech which was an extaxi with about 390,000km (only one key). I drove it from Brisbane to Darwin (Australia) - 4,000+k without an issue. Before I had a chance to get a second key (always my practice now) I had to lend it to a friend who was without a car. I gave strict instructions NOT to lose the key.... and guess what - key lost!!!! So off to the locksmith - 2 new virgin keys from Toyota and the car could start but remote not working. So the locksmith sent it to Toyota (we only have one dealer - next closest 1600k away and the one after that 3000+k). They couldn't code the remote either (said they were slave keys!) but provided a quote of several thousand dollars (nearly $10,000 from memory) to replace the computer and brake actuator (including $1000+ for a radiator replacement) - adding up to about twice what I paid for the car! They also replaced the inverter cooler because the car had escaped the recall (no cost to me).
So I have picked up the car and have VSC, ABS and (!) lights permanently on. I do not know when these lights became an issue in the vehicle's travels (not on in my possession of the vehicle). Brakes are functional but not working as well as before - feeling as though they are grabbing a bit - I am very reluctant to drive the vehicle at all. Scanguage II came up with nothing (not unexpected). Replaced battery with yellow optima - lights still on. Ensured the plug was well home in the brake device next to the battery. Jumped OBD2 4 and 13 and tried to reset the lights with the 8 brake pedal depression method but the lights remain on.
Flash codes are;
VSC 45
ABS 42
(!) 66
Couldn't seem to find out what these codes are.
My surmise is that the locksmith scanner caused the brake codes to erupt and Toyota then jumped to the conclusion that it was the brake actuator at fault (possibly previous codes rekindled???). Is there any other way of resetting the codes other than via Techstream? - I wonder whether I should buy a Techstream - may prove cheaper in the long run! Any thoughts re the remote function on the key?? When do I pull up stumps and replace the brake actuator ...Ouch!!
And the moral of the story are that there are some things in life you should never lend!
This forum is a wonderful font of knowledge and I am indebted to previous posters getting me as far as I have.

 

Thank you
Will try and get the mini VCI and report back

Hi again everybody.
Got the mini vci and found the code c1345 (linear solenoid valve offset learning undone). Used the Techstream to recalibrate - lights flashing 0.25 sec but unfortunately the c1345 fault code has persisted together with the warning lights still being on ... starting to think I may be up for the brake actuator. I do have a wrecked vehicle that I could pull parts off if there are other things to try before biting the bullet. Many many thanks once again.
