MechanMagic 3-Button Key Fob Replacement for Chevy/GMC 315MHz KOBUT1BT — Pair, Preloaded Batteries

MechanMagic replacement key fob: a 3-button, 315MHz KOBUT1BT remote preloaded with battery and electronics, ready to program for compatible Chevy, GMC and selected Cadillac models from the late 1990s to early 2000s.

If your original keyless entry remote stopped working, this MechanMagic aftermarket fob gives you a cost-effective way to restore remote locking, unlocking and trunk control without replacing the vehicle’s ignition or visiting a dealership. The unit matches FCC ID KOBUT1BT (part number 15732803), operates at 315MHz, and ships as a pair of identical 3-button transmitters with batteries installed and electronics pre-tested.

Which vehicles will this MechanMagic fob work with?

This remote was designed to match the keyless entry systems used on many late-1990s and early-2000s GM trucks, SUVs and some Cadillac models. Compatibility depends on the exact OEM remote type your vehicle originally used—verify FCC ID KOBUT1BT or part number 15732803 before ordering.

• Chevrolet: Tahoe, Silverado 1500/2500/3500, Suburban, Avalanche, S10, Astro (specific years listed on product)
• GMC: Sierra, Yukon, Jimmy, Sonoma, Safari (specific model years indicated)
• Cadillac: Escalade (selected 2002 models where this remote type applies)
• Always check the vehicle fitment tool and the remote’s FCC/part number for a precise match

How do I program the MechanMagic KOBUT1BT remote to my vehicle?

Programming is possible without dealership equipment if you have one working key fob already. MechanMagic includes a printed link to step-by-step programming instructions on the package; typical procedures follow vehicle-specific on-board programming steps.

• Requires one existing working remote or key for self-programming
• Simple on-board programming steps are provided via a URL printed on the package
• No credit card info or subscription required to access the instructions

What do I get in the box and what condition is the product in?

Each order contains two brand-new, identical 3-button keyless entry transmitters with batteries and internal electronics already installed. MechanMagic checks each unit electronically before shipping so they arrive ready for programming.

• Two brand-new KOBUT1BT 3-button remotes per order
• Batteries preinstalled and electronics pre-tested
• Comes with printed programming link and clear part/FCC identification

Are there any important limitations or notes before buying?

Not all late-1990s/early-2000s GM remotes use the same shell or frequency; ensure your vehicle uses FCC ID KOBUT1BT (15732803) and 315MHz before purchase. This transmitter is made for vehicles with a standard key (not integrated smart keys) and replicates button layout and functions only when matched to the correct OEM type.

• Only compatible with vehicles that originally used FCC ID KOBUT1BT / 15732803 at 315MHz
• Designed for standard-key vehicles, not smart-key or push-start systems
• Verify button layout, size, and part number against your original remote

Who is this for: This MechanMagic remote set is ideal for owners of supported Chevrolet, GMC or Cadillac models who need a budget-friendly, ready-to-program replacement for a lost or failed keyless entry fob. Choose this product if your vehicle’s original remote matches the listed FCC ID/part number, you prefer to self-program with an existing working key, and you want new, pre-tested electronics with batteries included.
