Vehicle Compatibility

Chevrolet

• Tahoe: 2015–2020

Important: This item is the Suburban / Tahoe application. A visually similar HYQ1EA smart key is used on Silverado and Sierra trucks with a Tailgate Release button instead of a Liftgate / Hatch button — the two are not interchangeable. Verify FCC ID HYQ1EA, the 433.92 MHz frequency, the button layout, the part number printed on the original remote, and the vehicle application before ordering or programming.

Programming & Compatibility

Professional programming is required.

Before programming, confirm that the original vehicle key matches:

• FCC ID: HYQ1EA
• Frequency: 433.92 MHz
• Button layout with Liftgate / Hatch Release
• Suburban or Tahoe proximity application
• Part number printed on the original remote
