Some customers said there is no reaction when their SKP-900 is connected to computer, and Carkeydeal will give you the solution.
Q: I want to add tokens for SKP900, but when I connect it to the computer, it can’t be recognized. How to solve it?
A: First, pls use windows XP system.
If it can’t work, then change another USB to try.
If it still doesn’t work, pls pull and insert the USB cable to check whether the device manager has reaction or not.
If above methods don’t work, please open main unit of your Auto Key Programming SKP900, check this chip, maybe this chip pins are loose, then solder the chip.
