Problem: I've followed the instructions to program a XM38 Universal Smart Key with Xhorse VVDI Key Tool Max programmer. But it fails all the time, and came out an attention: "Calculate failed(error code: Error:9B), please collect and retry!" Any ideas?

Solution
The reason why caused the issue is because of incorrect version. Please noticed to use same version of VVDI Key Tools & remote keys when programming.

For examples, use a GL version Key Tool Max to program a GL version remote key. In this case, the remote maybe a Chinese version remote. Users should pay attention to buy the correct version of VVDI Remotes.

Another tip to note: Most failed problems are due to wrong key model. Users should follow the instructions to program the correct key model.

In this case, XM38 key model is correct as required. But many users may make the mistake of buying a different model, such as XM28. Since both can program Toyota remotes.
