❓ Frequently Asked Questions (FAQ)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Q1: How do I know if this key is compatible with my vehicle?
A: Check your existing key for the B103 or PK3M keyway marking. This key uses the 13 chip and is compatible with 2000-2003 GM and Pontiac vehicles including Grand Prix, Bonneville, Montana, Impala, and Monte Carlo. If unsure, provide your VIN and we can confirm compatibility.
Q2: What is the 13 chip?
A: The 13 chip (also known as a TATA chip or PCF7930) is a fixed-code transponder used in early-2000s GM and Pontiac vehicles. It is a well-documented chip type that most locksmiths and dealerships can program without issues. This listing uses the OEM-quality chip version.
Q3: What is the difference between B103 and PK3M?
A: The B103 and PK3M are related keyway designations used in GM and Pontiac vehicles from the early 2000s. Both use the 13 chip. The specific keyway your vehicle requires depends on the model year and trim level. Always verify the keyway marking on the original key before ordering.
Q4: Do I need to program this key?
A: Yes. The B103/PK3M transponder key requires professional programming by a licensed locksmith or GM/Pontiac dealership. It is not self-programmable. Bring the key along with your vehicle's VIN to a professional.
Q5: Do I need to cut the key blade?
A: Yes. The key blade comes uncut and must be cut to match your vehicle's ignition. Your locksmith or dealer will handle this during the programming appointment.
Q6: How is this different from the GM B111 or B120 keys?
A: The B103/PK3M is an earlier GM keyway (2000-2003) using the 13 chip. The B111 (2004-2017) and B120/B121 (2008-2020) are later GM keyways using the 46 Circle+ chip. These keyways are NOT interchangeable — each uses a different chip and keyway profile. Always match to your vehicle's specific keyway and chip.
Q7: What is your return policy?
A: We offer a 1-year free return policy. If the key is defective or incompatible (verified before programming), contact us for a replacement or refund.
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.
