X AUTOHAUX Keyless Entry Remote Smart Key Fob for Buick Enclave & Encore GX 2020–2024, ID46 433MHz 5-Button

The X AUTOHAUX Keyless Entry Remote Smart Key Fob replaces your factory Buick Enclave (2020–2024) or Buick Encore GX (2021–2024) remote, matching OEM specifications (FCC HYQ4ES, ID46 chip) for reliable keyless control.

This aftermarket smart key fob is built to the same button layout and operating frequency as the original, so it integrates with your vehicle's existing locks, trunk release, panic alarm and remote start systems once professionally programmed. It ships with a pre-installed battery, durable plastic-metal construction, and the necessary FCC and part references printed on the case to help confirm compatibility before purchase. Note: this unit requires cutting and programming by a qualified locksmith or dealership and a working original key fob is typically needed to add a new transponder.

How do I confirm this remote fits my Buick?

Verify fit by comparing your old key’s FCC ID, part number, and button layout to the details printed on this remote. The X AUTOHAUX remote is specified for Buick Enclave 2020–2024 and Buick Encore GX 2021–2024, and includes the ID46 transponder chip and 433MHz frequency used by those models.

• Check FCC ID: HYQ4ES on the back of your original remote.
• Match the OE number 13530511 if available.
• Confirm the five-button layout and the ID46 chip type.
• Compare vehicle year and model before ordering.

What must I do to program and use the new key fob?

The new remote requires professional cutting and programming; it cannot be user-programmed in most cases. A working key fob is usually required to enroll a replacement; contact multiple locksmiths or your dealership if you run into programming issues.

• Bring the new remote and a working key to a qualified locksmith or dealer.
• Have the mechanical key cut to match your door/ignition if needed.
• Program the ID46 transponder and remote functions to the vehicle.
• Test all buttons (lock, unlock, trunk, remote start, panic) after programming.

What are the build and functional features of this key fob?

Constructed of plastic and metal components, this remote is designed to resist cracking and provide a stable tactile response from its buttons. It comes with an installed battery and mirrors the original key’s five-button arrangement for seamless operation once programmed.

• Durable plastic shell with metal reinforcement for longevity.
• Pre-installed battery included in the package.
• Sensitive button response for consistent operation.
• ID46 transponder and 433MHz frequency for OEM compatibility.

This product ships as a single car keyless entry remote with battery included. Inspect the appearance and printed identifiers on your existing remote—such as FCC ID and part number—before purchasing to ensure compatibility. Because programming and key cutting are required, assemble documentation or photographs of your original key to speed up service at the locksmith or dealer.

Who is this for? Owners of Buick Enclave (2020–2024) or Buick Encore GX (2021–2024) who need a direct-fit replacement remote are the primary audience. Choose this X AUTOHAUX smart key fob if you want an OEM-style backup or replacement that matches factory frequency and transponder specifications, and if you have access to professional key-cutting and programming services. If you don’t have a working original key or cannot obtain professional programming, consult your dealer for available options before purchasing.
