MechanMagic Replacement Key Blanks for Buick Chevrolet GMC HU100 46 Transponder (Set of 2) — Uncut Ignition Keys, Pre-tested

If your ignition key is lost, damaged, or you need a spare, these MechanMagic key blanks offer a cost-effective route to restoring vehicle access and engine start capability without buying a full remote. Each blank arrives brand-new, pre-tested for the embedded 46 transponder chip and ready to be cut and programmed to your vehicle. They are intended for standard keyed vehicles (not proximity/push-to-start passive-entry remotes) and cover a broad range of models when matched to the listed part numbers.

Which vehicles and part numbers do these keys work with?

These blanks match specific OEM key part numbers and many popular models from Buick, Chevrolet, and GMC across several years. Check your original key or dealer documentation for part numbers like 22984996, 5924205, 5924206, 7013237, 2428, or HU100 to confirm fitment. If you are uncertain, verify fitment with a dealer or locksmith before ordering.

• Chevrolet: Camaro, Caprice PPV, Colorado, Cruze, Equinox, Impala, Malibu, Silverado, Sonic, Spark, Suburban, Tahoe, Trax (2010–2021)

How do I get these uncut keys programmed and ready to use?

Each blank contains a factory-style 46 transponder chip and must be cut and programmed before it will start a vehicle. If you have a working original key, some vehicles allow DIY programming using that key and the new blank. Otherwise, a locksmith or dealership can cut the blade and program the transponder to your car’s immobilizer system.

• DIY programming may require an original functioning key present
• Professional locksmiths can cut and program the key on-site
• Dealerships provide key cutting and programming if needed

What are the product quality and usage limits I should know?

MechanMagic supplies these as 100% new, uncut ignition key blanks that have been inspected and tested for the microchip’s functionality before shipping. They are intended only for vehicles that use a traditional keyed ignition—this item will not operate passive-entry or proximity push-to-start systems. Confirm the key’s shape, blade profile, and remote layout against your existing key.

• New blank keys include pre-installed 46 transponder chip
• Not compatible with passive entry/proximity remotes
