How do I cut and program the uncut MechanMagic key?

The key arrives uncut and requires both physical cutting and transponder programming before it will start your vehicle. If you have one working original key, some vehicles allow DIY programming; otherwise a locksmith or dealership can perform both cutting and electronic programming.

• Cut the blank key to match your original key profile at a locksmith or hardware key service.
• Program the transponder chip using either on-car self-programming (if supported) or professional diagnostic equipment.
• Bring vehicle VIN and proof of ownership to a dealership or locksmith for dealer-level programming if DIY is not possible.
• Note: This product does not include remote functions—only the keyed transponder blade and chip.

What should I check before ordering MechanMagic replacement keys?

Confirming match details avoids returns and ensures the key will work after cutting and programming. Compare the physical key shape, OEM part numbers and whether your vehicle uses conventional keyed ignition.

• Verify the OEM numbers on your original key or existing documentation against the listed numbers.
• Check that your vehicle does not require passive entry/proximity remote as this blank won’t support those features.
• Compare pictures of the key head and blade to ensure the HU100 profile matches your original key.
• If unsure, contact your dealer or locksmith with VIN for definitive compatibility verification.

Who is this for: The MechanMagic HU100 46-chip set is intended for owners and technicians who need reliable, tested uncut ignition keys for compatible Buick, Chevrolet and GMC vehicles. It’s ideal for drivers replacing a lost key or creating a spare, and for locksmiths or fleet managers who handle cutting and programming. If your car uses passive proximity or integrated remote entry, choose a matched remote-capable replacement instead.
