Common Questions
How do I know if this is the correct key for my vehicle?
To confirm compatibility, match your original remote's FCC ID (HYQ14FBE), part number (89904-47460), PCB board number (0410), button configuration, and operating frequency with this listing. Your vehicle must also match the exact year, make, and model information shown in the compatibility list above before purchasing. Do not rely solely on vehicle year and model, as multiple key types may exist for the same vehicle.
Can I program this key myself?
No, self-programming is not available for this proximity smart key system. This type of high-security smart key fob requires professional programming setup by an automotive locksmith or an authorized dealership using specialized diagnostic equipment. Additionally, the included LXP90 emergency mechanical key blade must be cut by a professional to match your vehicle's physical locks before emergency use.
What is included with this key?
This product is a complete replacement solution. This listing includes the main smart key fob housing, fully functional internal electronics (including the transponder chip and circuit board), and a fresh CR2032 battery pre-installed. The un-cut LXP90 emergency mechanical key blade is also neatly included inside the smart fob assembly.
Full Compatibility & Product Details
This aftermarket smart key fob is engineered specifically for select 2017–2021 Toyota Prius / Prime vehicles equipped with factory push-to-start smart entry systems. Manufactured using high-quality components, it offers an affordable alternative to costly OEM dealership remotes while delivering identical functional integration for remote lock, unlock, panic, and trunk/remote commands depending on your specific vehicle's trim level configuration.
Before proceeding with your order, it is imperative to verify that your current key matches the technical specifications detailed on this page. You must double-check the FCC ID: HYQ14FBE, part number: 89904-47460, board ID: 0410, 315 MHz frequency, and LXP90 emergency key blade type. Discrepancies in any of these individual specifications will prevent the fob from programming successfully to your vehicle.
This Aftermarket unit serves as an ideal and reliable replacement for lost, broken, or water-damaged smart remotes, and can also be programmed as a secondary backup or spare key for everyday family use. Please ensure you have a certified professional locksmith or dealer lined up in your area to complete the programming process upon arrival.
