Thank you for your reply.

It seems that Toyota national dealer doesn't have the tools to do that. The reader seems to be working well because As soon I insert the key even with 95% of the body off, it recognizes. The problem happens always after I drive and then I stop it. Randomly it doesn't recognizes the key and I get the flashing light in the dashboard.

Sometimes I take the ground pin from battery and it works. But not always. Then I wait from 5 to 50 m and It works. I cannot keep living like this. Regards

If your dealer does not have the gear to do this, I do not know what you can do, I do not think that this can be re programed with out factory equipment, a dealer should have this equipment, it is in the basic inventory for dealership level service equipment.

100% with you, but I will try to do it at Johannesburg if they confirm that they have the tool.
Regarding Toyota dealers around here: they say that they are not obliged to accept imported cars for assistance.
I took the battery off for 40 minutes, because I read that will reset the ECU.

You really need a scanner to do a compleate code clear, but pulling the main ECU fuse will do it as well, let me know how you get on in Joberg.

That is a start signal fault, it will be tied in with the key problem.
