If you do not have a locksmith license, you can get the Toyota Techstream software without a lock and key business license. Essentially, tech stream is a program that interfaces with your car’s internal computer. Its most prominent purpose is to identify problems with the car’s function. When errors are detected, the software can offer greater knowledge to the local locksmith or mechanic. The software works with many vehicles, but it is not limited to Toyota models. To get the software, simply send your ID number to the seller of VXDAS. They will provide you with an activation code.
