MechanMagic Proximity Key Fob Replacement for Chevy Traverse/Blazer 2018–2020 — HYQ4EA 433MHz with Preinstalled Battery

MechanMagic’s ready-to-program proximity key fob replaces OEM HYQ4EA/13529636-style remotes for Chevy Traverse (2018–2020) and Blazer (2019–2020), supplying batteries and preinstalled electronics for immediate handoff to your locksmith or dealer.

If your original smart key is lost, damaged, or you want a spare, this MechanMagic key fob mirrors the form and signals of factory proximity remotes that use 433MHz and FCC ID HYQ4EA. The unit ships with batteries and internal electronics already fitted and has been bench-tested so a professional can complete vehicle programming without extra parts. It is built for push-to-start vehicles and matches several part numbers commonly found on Chevrolet key listings.

How do I get this key fob programmed to my car?

Programming must be completed by a dealership or a qualified locksmith with the appropriate diagnostic tools and security access. Because this fob contains factory-style electronics and security codes, only professionals can pair it to your vehicle’s immobilizer and remote start systems.

• Bring the fob and vehicle VIN to a dealer or certified locksmith
• Provide proof of ownership where required for security programming
• Expect programming time and possible immobilizer reconfiguration by the pro

What should I check before ordering to ensure fitment?

Confirm your vehicle’s year, model, and that it uses a push-button start system; review existing remote part numbers and FCC ID if accessible. Match the part numbers and HYQ4EA designation to verify compatibility so the professional programmer can connect the remote to your car without surprises.

• Verify vehicle: Traverse 2018–2020 or Blazer 2019–2020 with push start
• Compare existing remote part numbers: 13529636, 13519188, 13584514
• Check FCC ID on your old remote if available: HYQ4EA (433MHz)

Who is this for? MechanMagic’s proximity key fob replacement is designed for Chevy owners who need a direct-compatible spare or a like-for-like replacement after loss or damage, and for anyone preparing a vehicle for resale who wants reliable factory-style hardware.
