Key programming with 4D immoboxes: Tokai Rika 1st/2nd generation, VALEO and VISTEON

Separate immoboxes using the 40-bit 4D transponder: Tokai Rika 1st and 2nd generation, VALEO and VISTEON. Fitted to cars from 2002-2009 and still found on some US-market models. Programming is done via OBDII or by EEPROM dump.

Procedure

1. Prepare the transponder first: from "Transponder Tool" > "Production" > "4C/4D" menu, prepare it as ID67, ID70 etc. according to the vehicle's market (ID67 for Toyota/Scion, ID68 for Lexus, ID70 for Toyota Europe).
2. Instead of a virgin 4D you can emulate the 4D on a DST80 transponder (with page 3 writable), on a TPX2, or use an Abrites TA36 key.
3. VIA OBDII - Open "Special Functions" > "Key learning", let the software identify the immobox and follow the on-screen messages through to the end of learning.
4. BY DUMP - Remove the immobox and read its EEPROM memory with the ABPROG software (Tokai Rika: 93C66, ENCRYPTED dump; VALEO: 24C04; VISTEON: 93C56).
5. Open "Transponder Tool" > "Transponder by dump", load the EEPROM dump and program the transponder you prepared earlier.
6. Write the new dump modified by the software back into the immobox EEPROM memory with ABPROG, refit the module and check that the car starts.
7. Remember the general rules: the first key programmed after a reset must be a MASTER, and in many cases at least two registered keys are needed to close the learning.
