Xhorse Key Tool Max GM ID49 Proximity Cloning Pros and Cons

The Xhorse VVDI Key Tool Max is a powerful device for key programming, but many users overlook its advanced capabilities. In this guide, we’ll explore a hidden cloning method that bypasses traditional programming hurdles—no dealer support, no waiting for one-time codes, and no extra equipment needed.

GM 2021+ new style smart keys require one-time codes or dealer authentication, making aftermarket key programming difficult. Traditional methods involve:

  • Waiting for OEM codes (slow and costly).

  • Use official SPS programming

  • Buy the security pin code

  • Risking failure due to vehicle security restrictions.

Solution: The Xhorse Key Tool Max+ XM38 smart key combo allows direct cloning, bypassing these obstacles entirely.

Step-by-Step Cloning Process

1. Generate XM38 Key

  • Generate the XM38 smart key with the correct option.

  • If not pre-configured, flash it using the Xhorse software before starting.

4. Test the Cloned Key

  • Reinsert the XM38 key into the vehicle’s ignition.

  • Verify:

    • Ignition turns on/off.

    • Remote buttons work.

  • Note: The original key will no longer function (since its battery was removed during cloning).

Key Advantages of This Method:

No Dealer Involvement – Avoid costly dealership fees and wait times.
No One-Time Codes Needed – Bypasses the need for OEM authorization.
Works on “Problematic” Vehicles – Ideal for cars that reject standard programming.
Cost-Effective – Uses affordable XM38 keys instead of expensive OEM keys.

Limitations & Considerations:

Original Key Disabled – Removing the battery deactivates it permanently.
XM38 Key Dependency – Only works with Xhorse-compatible keys (no generic alternatives).
Chinese Interface – Some prompts may require translation (use Google or manual input).

Pro Tips for Success

Backup Original Key Data – If possible, extract immobilizer data before cloning.
Keep Multiple XM38 Keys – Some vehicles may require multiple attempts.
Use Google Translate – For Chinese prompts, take a screenshot and translate via mobile.
