Option 1:

Add key no need immobox if u haveToyota Techstream, try using Techstream is better than x100.

Techstream can’t reset immo.

When you get error “not a master key”, try to read pg1 and see.
You need master key, you can check it by insert key in switch ,if immo light goes immediately its master ,
if not its valid and need to get immo out.

Option 2:

I have done many of these Toyota G keys when all key lost, you need to remove the whole dash
to retrieve the Immo box which has 93C66 , writing Master G key byTango key programmer to start car.
You can add key only when you have master key.

P.S

I was told that in USA you can reset the Immo using M VP Key Programmer, but it is only for USA.
