LYFUCESS Smart Key Fob Replacement for GMC Sierra & Chevy Silverado 2022–2025 YG0G21TB2 433MHz, Includes Transponder & Battery

LYFUCESS smart key fob replacement YG0G21TB2 is a direct-fit remote for GMC Sierra and Chevrolet Silverado models from 2022–2025 that restores keyless entry and remote functions when your original fob is lost or damaged.

If your truck’s factory remote stopped working, this LYFUCESS replacement is built to match the button layout, frequency, and part numbers used on many 2022–2025 GMC Sierra and Chevy Silverado trucks. It ships with battery and transponder chip installed, and it’s tested before dispatch to reduce installation surprises. This product is an aftermarket replacement — no manufacturer logos — and it requires cutting and programming to pair with your vehicle.

How do I know this fob fits my GMC or Chevrolet truck?

Check three identifiers on your original key: FCC ID, part number, and frequency. The LYFUCESS remote matches FCC ID YG0G21TB2, part numbers 13548440 or 13548437, and operates at 433MHz. If those match, the housing and button layout should be compatible with your model years listed.

• Confirm FCC ID on your old remote: YG0G21TB2
• Match part numbers: 13548440 or 13548437
• Frequency must be 433MHz for correct radio communication
• Compatible model years: GMC Sierra / Chevy Silverado 2022–2025

What installation steps are required to make this remote work?

The remote arrives with the internal chip and battery preinstalled, but you’ll need a professional to cut the uncut blade and program the fob to your vehicle if self-programming isn’t supported. Programming instructions are included on the product packaging; dealers or locksmiths can perform full pairing and security syncing when needed. Every key is checked before shipping to ensure the electronics are functional.

• Have the blank key blade cut by a qualified locksmith
• Follow printed programming steps; if unsuccessful, seek professional programming
• Test all remote functions (lock/unlock, panic, remote start if applicable)
• Contact customer service for troubleshooting within 90 days

What features and limitations should I expect from this aftermarket fob?

This LYFUCESS remote includes a transponder chip and battery and is manufactured from durable materials for consistent performance. It is an aftermarket replacement, so it does not include OEM branding or vehicle warranty transfer — it’s intended to restore remote functionality affordably. Confirm compatibility before purchase to avoid returns.

• Includes chip and battery; tested before shipping

How quickly can I have the key ready to use once I receive it?

Once you receive the fob, allow time to have the blade cut and the remote programmed; many locksmiths or dealer shops can complete both tasks the same day. If your vehicle supports owner programming, you may be able to pair it yourself using the enclosed instructions. Keep the original remote available for reference to confirm button layout and FCC ID before cutting.

• Same-day service possible at many locksmiths or dealers
• Owner-programming may be available — follow package steps
• Retain original remote for identification of parts and layout
• Contact LYFUCESS support for help within 90 days
