Frequently Asked Questions (FAQ)

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

 

Q1: Which vehicles are compatible with this GM HU100 key shell?

A: This key shell fits GM vehicles that use the B119/HU100 high security key profile, including Chevrolet, GMC, Cadillac, and Buick models. The blade must be cut to match your specific vehicle's ignition. Verify your current key profile before ordering.

 

Q2: Does this key shell come with a transponder chip?

A: No. This is a key shell replacement only — no transponder chip is included. If your existing key has a working chip, it can be transferred to this new shell during rekeying by a locksmith.

 

Q3: Do I need to program this key shell?

A: The blade must be cut by a locksmith or dealership to match your vehicle. If you are transferring a chip from your existing key, no additional programming is needed for the shell itself. Consult your locksmith for details.

 

Q4: What is the difference between HU100 and B119?

A: HU100 and B119 refer to the same high-security key profile used by GM. HU100 is the mathematical classification of the cut profile, while B119 is the GM part number designation. They are interchangeable terms.

 

Q5: Is this an OEM GM key shell?

A: No. This is a professional-grade aftermarket key shell designed to OEM specifications. It is not manufactured by GM but is functionally equivalent to the original GM B119 key case.

 

Q6: How do I transfer my existing transponder chip to this new shell?

A: A locksmith can carefully transfer the transponder chip from your original key into this new shell. This process takes only a few minutes and ensures your vehicle will recognize the key after cutting.

 

Q7: What is your return policy?

A: We offer a 1-year free return policy. If the key shell is defective or incompatible (verified before cutting), contact us for a replacement or refund. Return authorization is required.

 

Q8: How long does shipping take?

A: Ships within 1–3 business days. Free shipping on orders over $100. Delivery typically takes 3–7 business days within the US.
