Keyecu Subaru Keyless Entry Remote Replacement HYQ14AHK (2018–2024) — 8A Transponder, Battery Included

This Keyecu remote key fob is a complete aftermarket replacement compatible with many Subaru models from 2018–2024 (FCC ID HYQ14AHK) and arrives ready to be cut and programmed to your vehicle.

Lost or damaged factory remotes can leave you stranded or paying dealer premiums — this Keyecu keyless entry remote provides an affordable, OEM-style substitute. It ships with the battery, uncut metal blade, 8A transponder chip, and the circuit board already installed, so a locksmith or dealer can quickly cut the blade and program the fob to your car. Before purchase, confirm the physical shape, button layout, and part numbers on your original key to ensure exact compatibility.

Which Subaru models and years will this Keyecu remote work with?

This replacement is designed to match the original key fob used across a range of Subaru vehicles. It fits Ascent (2019–2024), Crosstrek (2019–2023), Forester (2019–2023), Impreza (2017–2023), Legacy (2018–2021), Outback (2018–2023), BRZ (2022–2024), and WRX/STI (2019–2021).

• Full model coverage list included so you can check compatibility quickly.
• Ideal for owners of multiple Subaru trims using the HYQ14AHK remote profile.
• Not universal — confirm fit visually and by part number before ordering.

How do I confirm this remote matches my original key?

Inspect your current key’s exterior shape, button layout, and any printed part numbers on the shell or the circuit board. The Keyecu replacement uses the same board ID and transponder characteristics, so matching those identifiers ensures a correct swap.

• Check for FCC ID: HYQ14AHK on your original key or paperwork.
• Compare OEM part numbers: 88835-FL03A, 88835-FL03B, 88835-FL03C.
• Open the original housing to view board markings if uncertain, or consult a dealer if the key is lost.

What hardware and electronics are included, and what needs to be done before use?

The Keyecu fob arrives as a complete unit with battery, the uncut metal key blade, an installed 8A transponder chip, and the circuit board already in place. Because it is shipped uncut and unprogrammed, you must have the blade cut and the remote programmed by a qualified locksmith or a Subaru dealer for the vehicle to accept it.

• Included: battery, uncut blade, 8A chip, circuit board — ready for cutting and programming.
• Frequency: 433 MHz; Chip type: 8A; Board ID noted on the circuit board.
• Programming/cutting required — locksmith or dealership service recommended.

Will this remote perform the same functions as my original Subaru key?

Yes — once cut and programmed, the Keyecu remote performs keyless entry and remote locking/unlocking the same as your factory fob. It is intended to replicate the original feature set, but programming must match the vehicle to enable immobilizer and remote functions.

• After programming it supports remote lock/unlock and panic functions like the original.
• Immobilizer chip (8A) included to allow dealer or locksmith pairing with your car.
• Function parity depends on correct programming and vehicle compatibility.

Who this is for: Owners of compatible Subaru models who want a cost-effective, OEM-like replacement remote without waiting for dealer stock. It’s suited to drivers replacing a lost or broken fob who can visit a locksmith or dealer for cutting and programming, and to fleet managers seeking a straightforward spare key solution.
