KeylessOption Key Fob Replacement for Subaru 2010–2014 — 4-Button Pack of 2 with Programming Guide

Replacement 4-button KeylessOption fob (CWTWB1U819) — a pack of two programmable remote key fobs compatible with 2010–2014 Subaru Forester, Impreza, WRX and STI models.

If your factory remote is lost, damaged, or the battery fails, this set of two KeylessOption key fobs provides a practical, budget-friendly alternative. Each fob matches the original 4-button layout—lock, unlock, trunk (if equipped), and panic—and ships with a step-by-step programming guide so you can pair them with your vehicle without special equipment. The housings are built to fit the OEM key blade and electronics (transponder and remote board sold or programmed separately where required), making these useful for do-it-yourself replacement or as spares.

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

These remotes are designed to be compatible with many Subaru models from the specified years that originally used the CWTWB1U819 remote format. Verify compatibility by checking your current remote’s part number or year/model fit list before purchasing.

• Fits Subaru Forester, Impreza, WRX, STI, Outback, and Legacy where CWTWB1U819 is used.
• Compatible with 2010, 2011, 2012, 2013, 2014 model years for the listed vehicles.
• Confirm by matching the part number on your old remote or your vehicle’s repair documentation.

How do I program these remotes to my car?

KeylessOption includes a clear programming guide in the package that walks through the in-car steps. Some models allow owner programming using ignition and door sequences; others may require dealer or locksmith equipment for full transponder key pairing.

• Follow the included step-by-step manual for ignition-and-door programming procedures.
• If transponder pairing is required, a locksmith or dealer may be needed to program the immobilizer chip.
• Replace the battery and test buttons immediately after programming to confirm functionality.

What features and quality can I expect from these remotes?

These remotes reproduce the original 4-button layout and housing shape so they fit your vehicle’s key slot and button functions. They’re manufactured to provide dependable button response and durable plastic housings similar in feel to OEM remotes.

• Pack of two identical 4-button remotes for backup or dual-vehicle use.
• Durable ABS plastic shell and tactile silicone button pads for consistent operation.
• Comes with a programming guide and pre-cut key blade slot to accept your vehicle’s blade and internals.

What should I prepare before installing or programming?

Gather your vehicle’s owner manual, the original remote (if available), small tools to open the fob, and a fresh CR2032 battery. Knowing whether your vehicle requires transponder registration will determine if a professional is necessary.

• Original remote’s part number or a photo to confirm match with CWTWB1U819.
• Small screwdriver or plastic pry tool to open the shell and insert internals.
• Fresh battery (CR2032) and a locksmith contact if immobilizer programming is needed.

Who is this for? The KeylessOption CWTWB1U819 pack of two is ideal for Subaru owners who need an affordable replacement remote, a second spare fob for a partner or valet use, or a DIYer who prefers to handle programming themselves. It’s a practical choice when you want OEM-style button layout and reliable housing fit without paying dealer prices for a single unit. If you’re unsure about immobilizer or transponder requirements, check your vehicle’s documentation or consult a locksmith to confirm whether additional programming steps are required.
