MechanMagic Smart Key Fob Replacement for Chevy Suburban Tahoe & GMC Yukon XL 2021-2025 — 6-Button 433 MHz Push-Start

MechanMagic Smart Key Fob Replacement is a ready-to-cut, ready-to-program 6-button keyless remote designed for 2021–2025 Chevy Suburban/Tahoe and GMC Yukon/Yukon XL push-to-start vehicles (FCC ID YG0G21TB2, PN 13537962, 433 MHz).

This compact remote reproduces the factory-style functions for late-model Chevrolet and GMC full-size SUVs and ships fully assembled with battery and electronics. It is a brand-new aftermarket smart transmitter built to the same button layout as the OE unit and tested before dispatch. Note that it is intended for vehicles with push-button start and requires locksmith or dealer programming — it does not support self-programming.

Will this remote fit my 2021–2025 Suburban, Tahoe, Yukon or Yukon XL?

Compatibility covers Chevrolet Suburban and Tahoe and GMC Yukon and Yukon XL model years 2021 through 2025 when the original remote matches the six-button layout and FCC ID/part number. Use your vehicle’s current remote appearance and part numbers to confirm a match before ordering.

• Fits 2021–2025 Chevy Suburban and Tahoe, GMC Yukon and Yukon XL
• Matches FCC ID YG0G21TB2 and part number 13537962
• Intended for push-start (keyless ignition) vehicles only
• Check photos and vehicle fitment tool for exact match

How do I get this remote working with my vehicle?

The remote comes fully assembled with battery and internal electronics but must be cut and programmed by a qualified locksmith or a dealership. This ensures the transponder and remote functions are securely paired to your vehicle’s immobilizer and body control module.

• Requires professional cutting of the mechanical key if applicable
• Programming must be done with dealer or locksmith tools; no DIY setup
• Transponder and remote functions are pre-tested before shipping
• Bring vehicle info and original remote when you visit the programmer

What functions and frequency does the MechanMagic remote include?

The unit replicates the six-button layout commonly used on factory remotes: lock, unlock, remote start/aux (if vehicle equipped), trunk/hatch release, panic, and remote start or other OEM-assigned button. It transmits on 433 MHz and follows the original remote’s electronic design for reliable range and responsiveness.

• 6-button layout matching OEM controls
• 433 MHz transmission frequency for compatible models
• Includes internal battery and electronics already installed
• Pre-tested electronics for immediate programming

Are there any important limitations or notes before buying?

Remember this is a replacement transmitter for push-start vehicles only and will not work with traditional keyed ignitions that do not use the same FCC ID. The product arrives as a blank, programmable remote — it must be cut (if a mechanical key is included or required) and professionally programmed to your vehicle’s security system.

• Only compatible with push-button start vehicles
• Professional cutting and programming required
• Appearance: single 6-button shell as shown in photos
• Sold as a brand-new aftermarket remote; no self-programming
