How do I get the fob working with my car?

This is an aftermarket remote and does not support self-programming. A qualified locksmith or dealer must program the transponder and cut the metal key blade so the remote and car communicate securely.

• Requires professional programming (transponder sync)
• Metal key must be cut to match your ignition/door locks
• Bring original key info or VIN to the locksmith for faster setup

What should I expect in terms of quality and warranty?

Each YDTHTLAH unit is new and verified with testing equipment before shipment; it ships without Toyota logos as a non-OEM aftermarket product. If the remote fails under normal use, the seller provides limited support and a replacement or refund window.

• 100% new components, pre-installed battery and electronics
• Pre-shipment functionality testing
• Refunds or replacements available within three months
• Customer support response typically within 24 hours

Are there any installation caveats or compatibility pitfalls?

Double-check the part numbers and frequency before buying — wrong variants are common among Toyota models. Because this unit lacks manufacturer branding and may differ cosmetically from OEM fobs, ensure the remote’s circuit ID matches your vehicle’s requirements.

• Verify FCC ID and board number on your original fob first
• Non-OEM shell and no official Toyota logo
• Professional locksmith service required for programming and cutting

Who is this for: This YDTHTLAH replacement remote is aimed at Prius owners (model years 2010–2015) who need a fully tested aftermarket key fob matching HYQ14ACX specifications. It’s ideal for drivers replacing a lost smart key, restoring remote entry to a spare key, or fleet managers who want cost-effective, pre-tested remotes—provided they plan to have a locksmith or dealership perform transponder programming and blade cutting.
