YDTHTLAH Chevy HYQ4ES Key Fob Replacement — Fits Blazer/Traverse/Trailblazer & Bolt 2021–2024, 433MHz Proximity

This YDTHTLAH smart key fob is an aftermarket proximity remote engineered to replace HYQ4ES (FCC ID) keyless entry remotes for select 2021–2024 Chevy Blazer, Traverse, Trailblazer and 2022–2024 Bolt EUV/EV models.

If your factory key is lost, damaged or you need a spare, this replacement remote gives you the same proximity and lock/unlock functions as the original HYQ4ES fob. It ships with battery and electronics installed and is bench-tested before dispatch. Because it is an aftermarket part without Chevrolet branding, professional programming and metal key cutting are required to activate it for your vehicle.

Will this key fob work with my Chevy model and year?

Compatibility centers on the FCC ID and part numbers rather than just the vehicle name. This fob matches FCC ID HYQ4ES and part numbers 13535665 and 13530712, and operates on 433 MHz. Confirm those IDs or compare with your original remote to ensure a proper fit.

• Compatible vehicles: Chevy Blazer, Traverse, Trailblazer (2021–2024)
• Also fits: Chevrolet Bolt EUV and Bolt EV (2022–2024)
• Operates at: 433 MHz frequency
• Check your original remote for HYQ4ES, 13535665 or 13530712

How do I get this key fob programmed and ready to use?

This replacement requires professional programming and metal key cutting; it does not support owner self-programming. A qualified locksmith or dealership uses specialized tools to sync the remote’s electronics with your vehicle’s immobilizer and to cut the metal key blade to match your ignition.

• Bring the new remote and your vehicle to a locksmith or dealer
• Request remote programming and key blade cutting services
• Allow the technician to verify remote functions after programming

What features and quality assurances does this aftermarket fob include?

The unit arrives fully assembled with battery and internal electronics already installed and tested. Although it’s an aftermarket product and lacks OEM branding, each fob is quality-checked before shipping and backed by a short-term support policy for defects or compatibility issues.

• 100% brand-new remote with pre-installed battery and electronics
• Bench-tested for function before shipment
• Aftermarket unit without Chevrolet logo or OEM markings
• Customer support offers refunds or replacements within three months

Are there any important caveats I should know before buying?

Because this is not an OEM key, you should verify compatibility and budget for locksmith programming and cutting. The seller cannot program the device remotely; the vehicle must be present for final activation. Also confirm frequency and part numbers to avoid returns.

• Requires professional locksmith programming and metal key cutting
• No remote self-programming supported
• Verify FCC ID and part numbers before purchase to ensure fit
• Three-month refund or replacement support is available

Who is this for: This YDTHTLAH replacement fob is ideal for Chevy owners who need a reliable spare or a cost-effective replacement for a lost or damaged HYQ4ES remote. It’s best for buyers comfortable arranging professional programming and key cutting, and for those who verify the FCC ID/part number on their original key before purchase.
