Keymall Toyota Highlander 2008–2013 Smart Key Fob Replacement HYQ14AAB 4-Button ID47 314.3MHz

Keymall's Keyless Entry Smart Proximity replacement fob is a complete aftermarket remote (board 271451-0140, HYQ14AAB) built to replace the 4-button Toyota Highlander key fob from 2008–2013.

This compact replacement remote includes the internal circuit board, ID47 chip, CR1632 battery, and an uncut emergency key blade so you can restore full keyless entry functions for compatible Highlander SUVs. It’s an aftermarket unit without Toyota markings, intended as a cost-effective alternative to dealer remotes — but it must match your original remote’s board and FCC ID before purchase and be professionally programmed and cut to your vehicle.

How do I confirm this fob matches my Highlander?

Match markings on your original remote before ordering: the FCC ID must read HYQ14AAB and the green circuit board must show 0140 in the upper-left corner. If your board shows an “E” or the number 3370, this replacement will not be compatible.

• Check the FCC ID printed on your remote shell: HYQ14AAB.
• Open your old remote and inspect the green PCB for the number 0140.
• Confirm the OEM key part numbers and chip type match (ID47, 314.3 MHz ASK).
• Compare button layout and blade shape to ensure physical fit.

What comes in the package and what still needs doing?

The package contains one complete remote: circuit board, battery, ID chip, and an uncut emergency key blade. You will still need to have the blade cut and the remote programmed to your vehicle by a qualified automotive locksmith or technician.

• Included: remote with HYQ14AAB board, CR1632 battery, ID47 chip, uncut key.
• Not included: dealer programming — visit a locksmith for cutting and programming.
• Aftermarket housing lacks Toyota logo or part number on the case.
• Confirm programming compatibility with your vehicle before cutting the key.

How reliable is this aftermarket replacement compared to an OEM fob?

This Keymall remote uses the same internal board ID and transponder chip type as the genuine unit, offering equivalent electronic function when matched and programmed correctly. As an aftermarket option, it omits manufacturer branding and may differ cosmetically but serves the same operational purpose once installed.

• Uses ID47 transponder and ASK 314.3 MHz frequency as in originals.
• Comes preinstalled with a CR1632 battery for immediate testing.
• Aftermarket housing — identical internal circuitry, no OEM logo.
• Durability depends on handling and professional installation quality.

Which Highlander model years are supported and what are the exclusions?

This remote is intended for Toyota Highlander SUVs from model years 2008 through 2013 when the original remote matches HYQ14AAB and board 0140. It will not work if your original key uses a different board code, FCC ID, or button/blade configuration.

• Compatible: Toyota Highlander 2008, 2009, 2010, 2011, 2012, 2013 (SUV models).
• Not compatible if original board shows letter “E” or number 3370.
• Verify your OEM part number and board ID before ordering.
