Advanced Diagnostic Toyota Security Bypass Cable - ADC2021

Advanced Diagnostics is pleased to announce the new ADC2021 Gateway Bypass cable for select Toyota models allowing the programming of replacement proximity keys for popular models equipped with a BA system and DST-AES or Hitag-AES transponders.

What does the ADC2021 cable do?

The ADC2021 bypass cable connects directly to the immobilizer control unit (Certification Unit). Then it works with Smart Pro and Advanced Diagnostics ADS2328 software to program replacement keys without needing TIS codes. All functions, Add Keys, Erase Keys, and Immobilizer Reset now bypass the need for TIS codes. Check MYKEYS Pro for immobilizer control unit connection locations.

If all keys are lost, an emulator cable (ADC2015 or ADC2020 depending on the model) can emulate a working key, avoiding the 16-minute immobilizer reset function that erases the existing keys. Without the ADC2015/ADC2020 emulator cables all key lost situations are still serviceable with the immobilizer reset function.
