If you have a key or transponder simply place it near the antenna of the programmer and press the “Read/ Identify” button. A message about type of your transponder and content programmed will be displayed . If your transponder is some of the known transponder types information about this type (e.g. Texas Crypto 4D type ID67 – Master) will be displayed .

Abrites Diagnostics for Toyota/Lexus/Scion will try to recognize ONLY transponders/keys used in Toyota/ Lexus/Scion vehicles. These types are as follows:

• Fixed transponder Texas 4C. This type of transponder consist of only identification number and do not contain any authentication logic.

• ID33 transponders – this is another type of transponders that are using fixed numbers programmed in the transponder and are used for identification by the immobilizer system.

• Crypto transponder Texas 4D. This type of transponder consist of a set of data fields programmable by the user than can be used from immobilizer system to decide whether the key has been programmed in the vehicle. In addition this transponder provides the ability for programming of 40 bits secret keys which can be used by immobilizers to identify the transponder by a special authentication algorithm.

Depending on the content of these transponders they can be named as follows: ID67, ID68 and ID70.

ID67 is intended for usage by Toyota/Scion vehicles.

ID68 is intended for usage by Lexus vehicles.

ID70 is intended for usage by Toyota Europe.

• Crypto transponder Texas DST+. Generally this type of transponder is similar to Texas 4D with the exception that it provides a wide range of programmable data memory plus extended authentication algorithm – here the secret key is 80-bits.

These types of transponders are usually used in the smart systems (keyless keys) and also regular keys also known as G-chips (G-transponders).
