MechanMagic Toyota/Scion HYQ14ACX Key Fob Remote Replacement 3-Button 315MHz with Battery Installed

MechanMagic replacement key fob is a fully pre-tested 3-button remote programmed to match Toyota HYQ14ACX 89904-47230-style push-start vehicles, shipped with battery and electronics installed.

This MechanMagic keyless entry remote is a direct-replacement transmitter built to the HYQ14ACX specification and compatible with a wide range of Toyota and Scion models from roughly 2009–2019. Each unit is quality-checked with locksmith diagnostic equipment before leaving the warehouse, so the fob arrives ready for locksmith cutting and programming. It operates at 315 MHz and matches OEM part numbers like 89904-47230 and 89904-47370R, making it a convenient option when you need an OEM-style spare or replacement remote.

Which vehicles will this MechanMagic remote work with?

This remote fits many Toyota and Scion models that use the HYQ14ACX transmitter. It covers 3-button proximity remotes used on push-start vehicles—check compatibility carefully because it won’t operate conventional non-push-start keys or vehicles with certain passive entry systems.

• Common fits: 2010–2019 Toyota 4Runner, 2010–2015 Prius, 2010–2016 Prius V, 2012–2014 Prius C.
• Also compatible: 2009–2016 Venza and 2011–2016 Scion tC (verify exact years before purchasing).
• Confirm fit with vehicle fitment tool or OEM part number list before ordering.

What comes pre-installed and what will a locksmith need to do?

Each MechanMagic fob ships with the internal electronics and a battery already installed and fully tested. A qualified locksmith must cut the mechanical key portion and program the transponder and remote functions to your vehicle’s immobilizer and push-start system.

• Included: 1 x pre-tested remote with electronics and battery pre-installed.
• Required: locksmith cutting for the mechanical key and programming to the vehicle.
• Note: this transmitter only works with push-start vehicles and is not for standard key-only ignitions.

How does this remote match OEM specifications and performance?

MechanMagic builds this replacement to match OEM frequencies and board references so dealerships and locksmiths can program it like an original unit. The transmitter is tuned to 315 MHz with matching FCC/IC identifiers, enabling reliable communication with factory receivers when properly programmed and cut.

• Frequency: 315 MHz; IC: 1551A-14ACX; FCC reference HYQ14ACX.
• Compatible part numbers: 89904-47230, 89904-47370R, 89904-0T050, 89904-35010.
• Pre-testing: inspected with professional locksmith tools to verify electronics and battery function prior to shipping.

Who this is for: This MechanMagic fob is designed for owners, fleet managers, and locksmiths seeking an OEM-style replacement for Toyota/Scion push-start vehicles that use the HYQ14ACX transmitter. It’s ideal when you need a spare remote or a like-for-like replacement without buying a dealership-branded part, provided you have access to a qualified locksmith for cutting and programming. If your vehicle uses a non-push-start ignition or a passive entry/PEPS setup where doors unlock automatically when the key is nearby, this transmitter will not support those functions—confirm vehicle compatibility before purchase.
