Feedback on Obdstar X100 Pro Auto Key Programmer

Last week, I bought an obdstar X100 pro auto key programmer online to get the function of eeprom.

I got my obdstar X100 after 3 days delivery. The package was well protected without any damage. The package included a X-100 pro main unit, three different connectors, a main cable, a TF card and its card reader, the user manual and EEPROM adapter (the adapter is free in promotion).


I tried to test my car without any hesitation. But when I powered on the obdstar X100 pro, I even couldn’t find the selection of eeprom. What was wrong?


I asked customer service for help and she advised me to register on the and downloaded all update software first. How stupid I was! Here was the instruction the customer service sent to me to learn and use the device. Followed the steps with detailed descriptions and images, my update procedure had no problem.

Actually, the eeprom adapter was easy to do. I just registered and updated on obdstar official website with the authorization of eeprom adapter, and then connected obdstar X100 with my audi A3 and turned on the machine. Finally with X100 pro and eeprom adapter connected, followed the system operation and chose the function of eeprom would be enough.

It was worth to mention that I purchased the device at the best time because the online shop was in promotion that the eeprom adapter was gotten for free. I was not sure when  the promotion would be over. If anyone had the same requirements like me, just asked the customer service for answer.

To be honest, it is not convenient that this device can not do key programmer directly. if you have the need to do this module, you have to add extra module. I haven’t had this requirement yet, so I’m satisfied with obdstar X100 pro on the whole.
