Tactrix open port help

I don't believe there is a lot you can do without proper level security access.

 

I think the normal access is fine for pretty much all of the fob registering and deleting operations. The security-professional level is for completely reseeding the car in case all the original fobs have been lost.

But the thing with used fobs is that the normal procedures don't work with them. You can either get the used fobs revirginized, which then lets you use the normal procedures, or you have to proceed as if you were reseeding the car and re-registering every fob. Which normally requires the locksmith-level subscription; someone may have found alternatives, but I'm not knowledgeable about them.

 

No, the restrictions on the Smart Code Reset feature of the Toyota Techstream software aren’t specific to Prius cars or certain model years. As far as I know, all versions of Techstream, regardless of version number or source, require you to have some means—not provided in Techstream itself—to compute the pass-code number to enter when Techstream displays a vehicle-specific seed number during the reset procedure.

I’m aware of three ways to get pass-code numbers:

• Toyota dealers can follow the procedures in bulletin T-SB-0057-18, “Immobilizer and Smart Key Reset” (PDF);

• Locksmiths and others registered with NASTF can buy a Security Professional subscription to techinfo.toyota.com; and

• Anyone can buy a pass-code calculator program or calculation service from third parties, as mentioned in several PriusChat threads; like @ChapmanF, I don’t have any details of these to share.
