The Silca transponder chip references: T25, T10, T29, are precoded transponders which are ready 'off-shelf' for diagnostic programming, or can be cloned onto. The are pre-coded with a password, so the genuine Silca chip must be used (BDS or other brands cannot be written to by the RW4).

NOTE FOR DIAGNOSTIC PROGRAMMING: A Silca reference 'T5' transponder is designed to be universal between manufacturers and arrives to the user in a blank state. Prior to diagnostic programming, data must be pre-programmed onto the transponder with an RW4 or alternative supporting tool. An attempt to introduce an un-configured 'T5' to a vehicle will result in diagnostic key programming failure. Click here to view the T5 preparation procedure.

HOLDEN / OPEL ID40: Some Holden Astra, Vectra, Barina, Combo, Safira and Tigra models built between approx. 1998-2000 have clonable ID40 keys. Vehicles built after this date range change the implementation of this transponder so they CANNOT be cloned. There is no certain way to identify which keys can be cloned until an attempt is made with the transponder tool.

For Philips Crypto2 (HiTag2) ID46 transponder cloning, an in-car procedure must be performed using a 'Snoop' device (pictured left) to record some secret data from the vehicle. The procedure is simply cycling the existing key in the ignition 1 or 2 times while holdeing the Snoop adjacent to the key. After this the RW4 will 'crack' the code in less than 4 minutes. Click here for a video link of the procedure.

ID46 transponders for Holden (VE Commodore, Captiva) and Mitsubishi models from 2007+ require their transponder chips to be in a certain configuration BEFORE they can be diagnostically programmed into a vehicle. Silca GTI transponders can be configured with the RW4 TRP software, or the correct transponders can be purchased off-shelf here:

 

GM Circle + (VE Commodore, Captiva)

Mitsubishi CAN (Mitsubishi models 2007+)

Some early Kia and GM Daewoo use the Megamos Crypto transponder in a basic way (they have a generic crypto key) so transponder tools are able to clone these types instantly, without a requirement to 'sniff' the car - like other ID48 applications. Popular application examples in Australia are some early Kias, and the Holden TK Barina. Check the original key in the RW4 for confirmation.

The Temic Crypto ID8C can be cloned, but currently not with the RW4. Other LSC tools which support the function are Scorpio-LK Tango and the TMPro2

Identification of Texas Instrument crypto transponders (RW4)

There are multiple versions of TI crypto transponders, which in many cases are reverse compatible. This means a more modern, higher security transponder may be programmed into an older vehicle.

This causes great confusion because a new key blank purchased from a dealer to suit an older vehicle may have the latest, higher security transponder installed.The RW4 will identify the TI crypto transponder generation, and inform the user if it can be cloned.

After reading the transponder, the RW4 will present the identification with a prefix to indicate which generation of transponder is in the key.

prefix	Description
6F	Texas Crypto 2 (80 bit chip in old 40 bit mode). Can be cloned.
6A	Texas Crypto 3 (80 bit chip in new mode). Can't be cloned.
6E	Texas Crypto (with mutual authentication or new mode). Can't be cloned.

An identification example: '6A-63'.'6A' indicates a new 80 bit Texas Crypto transponder configured in 80 bit mode. The last two characters in the identification refer to the application configuration as featured in the table (63 for Ford/Mazda).
