YDTHTLAH Subaru Smart Key Fob Replacement for BRZ/Forester/Outback 315MHz (HYQ14AHC) — Preinstalled Battery, Requires Professional

YDTHTLAH smart key fob replacement for select Subaru models is a ready-to-program, battery-installed remote that restores keyless entry and remote locking functions.

This aftermarket replacement fob is built to match the electrical specifications and frequency of many Subaru vehicles from mid-2010s model years, offering a cost-effective way to replace a lost or damaged factory remote. It ships with the internal electronics and battery pre-installed, but requires professional programming and a cut metal key to activate vehicle functions. Read on to confirm compatibility, learn programming requirements, and see what to expect from the purchase.

Will this key fob work with my Subaru model and year?

This fob is designed to be compatible with Subaru models that originally used FCC ID HYQ14AHC and part number 88835-AL04A at 315 MHz. Always compare your existing key fob’s FCC ID, part number, and frequency before ordering to avoid incompatibility.

• Compatible models include Subaru BRZ (2014–2020), Forester (2016–2018), Legacy and Outback (2015–2017).
• Also fits Crosstrek XV and Impreza WRX/WRX STI or Impreza (2015–2018) where that FCC ID was used.
• If your current remote has a different FCC ID, frequency, or part number, this unit will likely not work.

How is the key fob activated and programmed?

This replacement requires professional programming and a metal key cutting service; it is not set up for self-programming. A certified locksmith or Subaru dealer with the correct diagnostic tools will pair the remote to your vehicle and cut the physical key blade to match your locks or ignition.

• Bring the new fob and your vehicle to a locksmith or dealer for transponder programming.
• Expect to have a metal key blade cut to your vehicle’s original key profile.
• This aftermarket product is sold without Subaru branding and does not include proprietary dealership packaging.

What features and quality can I expect from this aftermarket fob?

The YDTHTLAH fob ships brand-new with the internal battery and electronics already installed and bench-tested. While it reproduces the same remote functions—lock, unlock, and panic—note that cosmetic details and logos differ from OEM units.

• Pre-installed battery and electronics are tested before shipment for immediate readiness for programming.
• Functions mirror original remote operations (keyless lock/unlock and panic), assuming successful programming.
• Aftermarket finish: no Subaru logo or OEM branding included.

What if the fob doesn’t work or I need support?

YDTHTLAH provides customer support and a limited refund or replacement window to address defects or delivery issues. Contact the seller promptly if you encounter problems during installation or programming to receive guidance or a remedy.

• Support available for questions before and after purchase; typical response within 24 hours.
• Refunds or replacements supported within three months for qualifying issues.
• Keep proof of purchase and photos of the existing key and vehicle for faster assistance.

Who is this for: This replacement key fob is a practical option for Subaru owners who need a lower-cost aftermarket remote that matches specific FCC ID/part-number specifications and are prepared to use a professional locksmith or dealer for cutting and programming. Choose this unit if your vehicle year and model match the listed compatibility, you accept an unbranded aftermarket housing, and you want a tested remote ready for professional activation.
