Programming new keys and FOBs for your vehicle can seem daunting, often leading car owners straight to the dealership. However, with the right tools and a bit of know-how, DIY key and FOB programming is achievable, potentially saving you a significant amount of money and time. This article shares a personal journey of programming keys and FOBs for a 2010 Toyota Tundra, exploring two popular methods: using an Autel MX808 scanner and delving into TechStream software with an OBD2 to USB cable.
Initially faced with the need for extra keys and FOBs, two distinct paths were explored. The first involved utilizing readily available OBD2 software, aiming for a solution that offered broader vehicle customization beyond just key programming. The second approach focused on a dedicated OBD2 scanner, the Autel MX808, known for its key and FOB programming capabilities.
Autel MX808 Scanner: A User-Friendly Solution
Opting for the Autel MX808, sourced from eBay, proved to be a cost-effective alternative compared to dealership programming fees. This scanner impressed with its ease of use and intuitive interface. Within an hour, two keys and three FOBs were successfully programmed. The process was straightforward, making it accessible even for those with limited experience in automotive diagnostics.

However, a limitation was encountered with the Autel MX808. Despite the desire to program three keys for backup purposes, the scanner seemed restricted to a maximum of two keys. Attempting to program a third key resulted in one of the previously programmed keys becoming inactive. This unexpected constraint necessitates further investigation to understand the underlying cause and potential workarounds.
TechStream and OBD2 to USB Cable: Exploring Deeper Diagnostics
The second approach involved venturing into the realm of TechStream, Toyota’s diagnostic software. Acquiring a copy of TechStream version 10.XXX.XX, generously provided by RainMan_PNW along with installation guidance for Windows 10, marked the beginning of this exploration. To ensure compatibility and avoid potential software conflicts, a dedicated, lightly used Toshiba laptop running Windows 7 (32bit) was chosen as the platform for TechStream. An OBD2 to USB cable, obtained from Amazon and bundled with a purported copy of Techstream Ver 15, completed the hardware requirements.

The intention behind using a dedicated offline laptop was to mitigate potential malware risks, a crucial consideration when dealing with diagnostic software and vehicle systems. The TechStream route promises deeper access to vehicle settings and functionalities beyond key programming, offering potential for further customization and diagnostics. However, the journey with TechStream is ongoing, requiring further setup and testing to fully assess its capabilities and compare it to the Autel MX808 for key and FOB programming and broader vehicle management.
Further updates on the TechStream setup and its performance are anticipated. Community input and shared experiences regarding key and FOB programming, particularly with these tools, are highly welcomed.
