MechanMagic 3-Button Key Fob Remote for Chevy GMC 2-Pack — KOBUT1BT 315MHz, Pre-Tested & Battery-Installed

MechanMagic replacement key fob KOBUT1BT is a ready-to-program 3-button remote that restores keyless entry for many Chevy, GMC and Cadillac models from the late 1990s to early 2000s.

This MechanMagic remote is a direct aftermarket substitute for FCC ID KOBUT1BT (part number 15732803) and transmits at 315MHz. Each set includes two fully tested 3-button transmitters with batteries and internal electronics installed so you can program them to a compatible vehicle. Before buying, verify compatibility with your vehicle year and model—several different remotes were used across model years, so matching FCC ID, part number or console key type is essential.

Will this MechanMagic fob work with my Chevrolet or GMC model?

Many Chevrolet and GMC vehicles built between roughly 1998 and 2002 use this style of 3-button remote; compatible models include Silverado, Tahoe, Suburban, S10, Sierra, Yukon, Jimmy and several others. Confirm the FCC ID (KOBUT1BT) or part number 15732803 matches your current fob or dealer listing for a reliable fit.

• Chevrolet: Avalanche (2002), Astro (2000), S10 (1998–2001), Silverado 1500/2500/3500 (1999–2001), Suburban/Tahoe (2000–2002)
• GMC: Safari/Yukon (2000–2001), Sonoma (1998–2001), Sierra 1500/2500/3500 (1999–2001), Jimmy (1998–2001)
• Also listed for Cadillac Escalade (2002); always double-check with fitment tool or dealer

How do I program these MechanMagic remotes myself?

These remotes are designed for owner programming when you have at least one working key present. The package includes a printed link to step-by-step programming instructions, and no third-party account or payment information is required to access them.

• Requires one working original key for the vehicle during programming
• Instructions provided via a URL printed on the package for convenience
• Self-programming typically involves turning the ignition and pressing buttons in a sequence—follow the exact steps for your model year

What comes in the box and what should I expect from quality?

Each purchase contains two brand-new 3-button MechanMagic remote transmitters preloaded with batteries and tested electronics. Units are tested with professional equipment before shipping so they arrive ready to program and use.

• Two identical 3-button remote transmitters included
• Installed battery and pre-tested circuitry for immediate programming
• Clear labeling of FCC ID and part number for easy verification

Are there any important limitations or compatibility notes?

This transmitter is intended for vehicles that use a standard mechanical key in addition to remote entry—it will not replace transponders or smart keys used by other systems. Because multiple remote variants existed across years and trims, confirm button layout and FCC ID match your existing fob before purchase.

• Only compatible with regular-key vehicles (not immobilizer-only smart keys)
• Check button function, placement and FCC ID against your original remote
• If unsure, consult dealer or the vehicle fitment tool for verification

Who is this for: The MechanMagic KOBUT1BT 3-button remote is for owners of late‑1990s to early‑2000s Chevrolet, GMC or Cadillac vehicles who need an affordable, ready-to-program replacement for lost, damaged or worn factory fobs. It suits DIYers who want owner-programmable remotes and technicians who need pre-tested spares; just verify the FCC ID/part number and that your vehicle accepts a standard mechanical-key remote before purchasing.
