Which vehicle models will these replacement remotes work with?

These 3-button HYMOLKYE remotes are made to match the remote frequency and button layout used by many late‑90s and early‑2000s GM vehicles. Confirm compatibility by checking your original remote’s FCC ID and button arrangement before purchasing.

• Compatible examples: 1998–2001 Blazer, 1999–2004 Silverado, 2000–2004 Suburban and Tahoe
• Also fits: 1999–2003 GMC Yukon, 2000–2004 Sierra, 1998–2001 Oldsmobile Bravada
• Double-check FCC ID: KOBLEAR1XT or KOBUT1BT printed on your original remote

How do I program these HYMOLKYE key fobs myself?

Self-programming is straightforward and designed so most owners can finish in minutes without special tools. You will need an existing working key and the vehicle’s ignition to complete the sequence; follow the included programming steps carefully for success.

• Requires at least one working ignition key and the vehicle present
• Follow the remote’s step-by-step programming sequence to sync frequency
• No dealer visit or specialized scan tool generally required

What features and quality assurances come with these remotes?

Each HYMOLKYE remote is delivered fully assembled with a battery and pre-tested before shipping to help ensure immediate use. The housings replicate the original 3-button layout so functions like lock, unlock and panic (if applicable) operate as expected once programmed.

• Ships as a pack of two pre-installed batteries for instant testing
• Pre-tested electronics and correct FCC IDs for compatible vehicles
• Affordable replacement or spare without compromising core functionality

What should I check before buying to avoid compatibility issues?

Compatibility depends on the remote’s FCC ID, physical button layout, and the vehicle’s year and model. Inspect your current remote and match the FCC ID and number of buttons to the HYMOLKYE listing to ensure a correct fit.

• Confirm FCC IDs printed on your old remote: KOBLEAR1XT or KOBUT1BT
• Ensure your original has the same 3-button layout (lock/unlock/panic)
• Verify the vehicle model and year fall within the supported list

Who is this for? Car owners of late‑1990s to early‑2000s GM trucks and SUVs who need a low-cost replacement or spare remote, drivers restoring a vintage vehicle, and anyone wanting a quick DIY fix without dealer programming fees. If you own one of the supported Chevrolet, GMC, Cadillac, or Oldsmobile models and can provide a working ignition key for programming, these HYMOLKYE remotes make a practical, ready-to-program solution.
