HelloAuto Replacement 6-Button Key Fob HYQ1AA for 2015–2020 Chevy Tahoe/Suburban & GMC Yukon XL Denali — Chip & Battery Installed

This HelloAuto replacement key shell is designed as a full-function swap for worn or damaged remotes used on Chevy Tahoe, Suburban and GMC Yukon XL/Denali models from about 2015–2020. The unit ships complete with the transponder chip, circuit board and a pre-installed battery so you can skip salvaging parts from an old fob. It requires dealer or locksmith-style programming to sync with your vehicle, but otherwise arrives ready for immediate installation into your key blade and vehicle pairing process.

How does this replacement fob match the original remote?

The shell and electronics mirror the factory HYQ1AA design so button layout, frequencies and signal functionality align with the original remotes. Button labels and tactile feel are recreated for consistent use, and the pre-installed battery ensures the unit powers up immediately on first programming.

• Exact 6-button layout for lock, unlock, remote start, trunk, panic and programmable functions
• Built-in transponder chip matching HYQ1AA systems
• Pre-soldered circuit board for plug-and-play programming
• Pre-installed battery for immediate power during setup

What steps are required to get this fob working with my vehicle?

You will need to have the fob programmed to the vehicle using a dealer-level tool or an automotive locksmith’s programming device. Programming is specific to your vehicle’s security module and may require all existing remotes present or a master key for enrollment.

• Confirm vehicle uses FCC ID HYQ1AA before purchase
• Bring the new fob to a dealer or certified locksmith for programming
• Some vehicles require on-car programming with all remotes present
• Insert the mechanical key blade if door access or ignition is needed during setup

Will I need to transfer parts from my old fob?

No disassembly of your original remote is necessary unless you want to reuse the mechanical key blade or a specific key ring. This HelloAuto replacement arrives complete, so most buyers only remove the old blade or cover and fit the replacement as the new primary remote.

• Comes with chip, board and battery already installed
• Mechanical key blade may need to be swapped if not included
• Minor case trimming not required for proper fit
• Tools may be needed only to remove old blade or open key slot

How durable and reliable is the replacement shell?

The housing is molded from durable plastic with button membranes engineered for repeated use and weather resistance similar to factory remotes. While not an OEM-branded part, the construction is intended to withstand typical daily wear and provide consistent signal performance after professional programming.

• Hard-wearing exterior casing compatible with factory mounting points
• Sealed button contacts to reduce dirt and moisture ingress
• Designed for long-lasting tactile response and button longevity
• Backed by HelloAuto quality checks at shipment
