What exactly comes in this 4-key set?

This listing bundles four uncut key blanks: a pair of Strattec #320588 (OE #01154610) and a pair of Strattec #320589 (OE #01154611). The kit supplies the two distinct gate profiles used on many GM vehicles so you have both ignition and entry/trunk options on hand for rekey jobs.

• 2 x Strattec #320588 — "A" primary square-gap ignition blanks
• 2 x Strattec #320589 — "B" secondary oval doors/trunk blanks
• Surface finish: nickel silver for corrosion resistance and cutting precision
• Made in the United States, OEM-style fit and spacing

Which vehicles use these blanks and how do I confirm fit?

These blanks are intended for select GM models that use the new GM logo key blank pattern. Fit depends on the vehicle's original factory key profile and gate pattern; always verify by comparing the blank to the original key or the manufacturer's key code before cutting.

• Compare shape and gate layout to your original GM key
• Check OEM part numbers: 01154610 (A) and 01154611 (B) for compatibility reference
• Contact a locksmith or dealer with vehicle year, make, and VIN for confirmation

How are these keys meant to be used and cut?

These are uncut blanks meant for key cutting and, where applicable, programming with a vehicle's transponder system. A professional key cutter or locksmith should duplicate the key profile using a code or by tracing an original key; ignition transponder chips, if required, must be handled per the vehicle's security system procedures.

• Use a calibrated key cutting machine for precise duplication
• Provide the locksmith with original key or key code for exact cuts
• Transponder programming may be necessary for ignition operation—confirm with vehicle manual

Why choose Strattec blanks over generic alternatives?

Strattec manufactures blanks to OEM tolerances, which reduces filing or shim adjustments during cutting and helps ensure reliable engagement with locks and ignition cylinders. The nickel silver finish resists wear and provides smooth key cutting and insertion, while the matched A/B gate set covers both ignition and entry functions commonly separated in GM keys.

• OEM-style manufacturing for accurate key geometry
• Nickel silver finish for durability and precise cutting
• Included A and B gates save time sourcing separate blanks

Who is this for: This four-key set is aimed at professional locksmiths, dealerships, fleet managers, or informed DIYers who service GM vehicles and need OEM-style, uncut blanks for rekeying, duplication, or inventory. If you require exact-fit blanks for ignition and doors/trunk with a factory-like finish and clearly referenced part numbers (320588 and 320589), this set provides both profiles in a single purchase.
