USARemote Subaru 4-Button Key Fob Replacement CWTWB1U811 (2012–2019) — Pre-batteried, Uncut Key Blade

USARemote's 4-button key fob replacement is an aftermarket keyless entry remote compatible with select 2012–2019 Subaru models that arrives pre-batteried and ready for professional programming.

This replacement remote fits Subaru Impreza, WRX, Forester, XV, Crosstrek, Outback and Legacy vehicles from model years 2012 through 2019 when equipped with the matching OEM frequency/chip (CWTWB1U811 / 4D-82 G chip). It provides all four standard functions—lock, unlock, trunk/panic—and includes an uncut mechanical key blade built into the head. The shell and internal electronics are supplied fully assembled so the remote is ready for dealership or locksmith programming upon arrival.

How will this fob match my Subaru model and key system?

Compatibility depends on both the vehicle year/model and the factory key transponder type. Confirm your car’s original remote part number or the transponder chip type before ordering to avoid mismatch.

• Designed for Subaru 2012–2019 Impreza, WRX, Forester, XV, Crosstrek, Outback, Legacy
• Uses CWTWB1U811 designation and 4D-82 G transponder chip
• Check vehicle documents, driver-side door jamb, or original remote for part number
• Not compatible without matching OEM frequency/chip—verify before purchase

What needs to be done after I receive the remote?

The remote arrives with the battery and electronics installed but will not operate with your vehicle until a professional programs it to your car’s immobilizer. The mechanical key is uncut and must be sized to your ignition and doors by a locksmith or dealer.

• Take remote to an automotive locksmith or Subaru dealership for programming
• Provide proof of ownership and vehicle details as required by service providers
• Have the uncut key blade professionally cut to match your ignition/door locks
• No in-case assembly or battery installation required—pre-installed and sealed

What are the product’s build and functional features?

This aftermarket remote shell is built to withstand daily handling while maintaining the same button layout and user functions as the factory item. It’s a practical replacement when the original fob is lost, damaged, or buttons no longer respond.

• Durable non-logo aftermarket shell engineered for longevity
• Includes lock, unlock, trunk/panic buttons with OEM-style tactile response
• Pre-installed battery and factory-equivalent internal electronics
• Supplies full keyless-entry functionality once programmed to the vehicle

Are there installation or legal considerations I should know?

Yes—programming must be performed by an authorized locksmith or dealership and many providers require proof of ownership. The fob is sold as a replacement component, not pre-linked to any vehicle, to meet security and legal standards.

• Programming cannot be completed by the user in most cases—professional service required
• Bring vehicle registration or title to the locksmith/dealership for identity verification
• Uncut key blade prevents unauthorized use until professionally cut and paired
• Follow local regulations and dealer policies for key/transponder reprogramming

Who is this for? This USARemote replacement is intended for Subaru owners who need a ready-to-program spare or replacement fob for compatible 2012–2019 models. It’s a practical choice if your original remote is lost, broken, or the shell is worn, and you’re prepared to have the unit professionally programmed and the key blade cut. Not suitable if you cannot confirm the vehicle’s chip/part number or if you need a pre-programmed unit.
