MechanMagic Key Fob Replacement 2-Pack — 3-Button 315MHz Remotes for Chevy/GMC (15732803)

MechanMagic's 2-pack KOBUT1BT key fobs are direct-fit replacement remotes for many Chevy, GMC and select Cadillac models from about 1998–2002, preloaded with electronics and a battery and ready to program at 315MHz.

If your OEM keyless remote is lost, damaged, or worn, this MechanMagic set gives you two fully assembled 3-button remotes (part number 15732803 / KOBUT1BT) built to match the original functions for a range of Chevy, GMC and some Cadillac vehicles. Each fob ships with the internal circuit board and battery installed and is tested before shipping. Because several different remote versions exist across model years, confirm your vehicle’s FCC ID, frequency and key style before buying to ensure compatibility.

Will these remotes work with my specific Chevy or GMC model?

These replacements cover many common GM vehicles from the late ’90s through early 2000s, but not every variant. Use the part number, FCC ID and frequency to confirm fitment; the package also includes a printed link to programming steps.

• Compatible part number: 15732803 (FCC ID KOBUT1BT).
• Operating frequency: 315 MHz—check your vehicle’s OEM remote frequency.
• Common fits: Chevy Tahoe, Silverado, Suburban, S10, Avalanche, Astro (select years) and GMC Sierra, Yukon, Sonoma, Safari, Jimmy (select years).

How do I program these remotes to my vehicle?

MechanMagic remotes are designed for self-programming when you have one working vehicle key available. Programming steps vary by year and model; the printed link on the package walks you through the process without payment or account registration.

• Requires one working key for on-vehicle programming.
• Follow the included programming link for step-by-step instructions specific to many GM vehicles.
• No dealer visit or subscription is necessary for many models—just follow the on-vehicle sequence.

What does each replacement fob include and how reliable are they?

Each MechanMagic remote arrives fully assembled with battery and electronics installed, and is tested before shipping. They are brand-new housings and circuit boards intended to match OEM keyless entry functions, though they work only on regular (non-transponder-only or specialized) key systems as noted.

• Two 3-button remotes per order—lock, unlock, and panic/function layout.
• Pre-installed battery and pre-tested electronics for quicker setup.
• 100% new housings and internal components—sold as replacement remotes, not blank shells.

Are there any important purchase checks or limitations?

Because GM used multiple remote variants across model years, confirm that the FCC ID and button layout match your existing remote before purchasing. These transmitters work with standard non-specialized key systems only.

• Double-check FCC ID = KOBUT1BT and part number 15732803 for fitment match.
• Works at 315MHz—verify your vehicle’s remote frequency first.
• Not intended for vehicles requiring dealer-only programming or specialty immobilizer modules.

Who this is for: MechanMagic’s dual-pack is aimed at owners of late‑1990s to early‑2000s Chevy, GMC and some Cadillac vehicles who need a practical, cost-effective replacement for lost or failing keyless remotes. It suits DIYers who want a ready-to-program remote with battery and electronics included, as well as technicians and fleet managers replacing multiple fobs. If you’re unsure whether this exact remote matches your car, check the FCC ID and part number printed on your original fob or consult your dealer before ordering.
