MechanMagic Chevrolet Equinox Key Fob Replacement 2018-2021 — 5-Button 315MHz, Pre‑Installed Battery

MechanMagic's pre‑installed 5‑button replacement key fob is a ready-to-program remote designed to replace the original Chevrolet Equinox smart key (2018–2021) with FCC ID HYQ4AA.

If your Equinox smart key is lost, damaged, or simply unreliable, this direct‑fit replacement gives you the same push‑button remote functions in a new housing. The unit ships with the internal electronics and battery already installed and pre‑tested, matching part numbers 13584498 and 13529650 and operating at 315MHz. Because programming requires a qualified locksmith or dealership, the fob arrives ready for professional setup rather than DIY pairing.

How does this replacement match my original Chevrolet Equinox key?

This MechanMagic replacement is built specifically to match the smart‑key profile used on Chevrolet Equinox models from 2018 through 2021. It uses the same FCC ID (HYQ4AA) and works with the listed part numbers to ensure compatibility with vehicles equipped for push‑button start.

What features and functions will I get after programming?

Once professionally programmed, the key fob restores the standard keyless entry and remote start functions expected on late‑model Equinox vehicles. It includes five clearly marked buttons for locking, unlocking, remote start, panic, and power liftgate or trunk depending on your vehicle configuration.

• Five-button layout for lock, unlock, remote start, panic, and trunk
• Remote start capability on equipped vehicles with push‑button start

How do I get this fob programmed to my vehicle?

Programming requires professional equipment and credentials; MechanMagic ships the fully assembled fob for a locksmith or dealer to program into your vehicle’s security system. Self‑programming is not supported, so plan to contact a certified locksmith or Chevrolet dealer for final setup.

• Bring the fob and vehicle to a locksmith or Chevrolet dealer
• Professional tools are used to add the fob to the vehicle’s immobilizer
• Expect confirmation tests for all buttons and remote start (if applicable)
• Ask the technician to verify battery voltage and signal transmission

Check your vehicle’s original key part number before purchase to confirm compatibility, and consult the seller for any warranty or return details.

• Ships as one complete key fob with battery and electronics installed
• Intended only for push‑button start vehicles, not for standard keyed ignitions
• Verify compatibility using part numbers 13584498 and 13529650
