Modifying HON66 to VA2T Key Blank via Xhorse Condor XC-MINI Plus II

The Xhorse Condor XC-MINI Plus II and Dolphin II Key Cutting Machine feature the "Modify Key" function. This guide demonstrates how to convert an HON66 key blank into a VA2T key blank using this capability.

Step 1: Modify HON66 to VA2T

Since the HON66 blank is wider than the VA2T, we need to remove the excess material.

1. Select "Modify Key" → Choose VA2T as the target blank.

2. Follow the on-screen instructions to install the HON66 blank.

3. Start cutting with default settings → The machine will begin automatically.

4. Wait until the process completes—the edge of the HON66 will now be partially trimmed.

5. Reinstall the key blank in reverse to cut the remaining excess.

6. You now have a custom VA2T key blank!

Step 2: Copy a VA2T Key

Now, we can use the modified blank to duplicate a VA2T key.

1. Navigate: Automotive → Key Blank → VA2T.

2. Rotate the M5 clamp to Side B and insert the original key.

3. Select "Decode Key" to learn the cuts.

4. Once decoded, remove the original key and insert the new blank.

5. Start cutting → Repeat for the other side.

6. Cutting completed!

The new key works perfectly and opens the lock smoothly.
