Subaru BIU / BCM Clone Programming Service | Body Integrated Unit | 2005–2021

Subaru BIU / BCM Clone Service | Body Integrated Unit Programming

This service provides cloning and programming of Subaru BIU (Body Integrated Unit) / BCM modules that use the standalone black-box style module.

If your original BIU has failed due to water damage, corrosion, electrical faults, or internal failure, we transfer the necessary vehicle-specific data from your original module into a compatible replacement module that you provide. This allows the replacement BIU to retain the original vehicle's immobilizer, security, and configuration information and function as a plug-and-play replacement in most applications.

What Is a Subaru BIU / BCM?

Subaru commonly refers to this module as the Body Integrated Unit (BIU). However, used parts, salvage yards, repair shops, and online listings may use several different names for the same or similar module, including:

• Body Integrated Unit (BIU)
• Body Control Module (BCM)
• Body Control Unit
• Integrated Unit / Integrated Unit Assembly
• Integrated Control Module
• Multifunction Control Module
• Body Control Computer
• Anti-Theft / Security Control Module

This listing is specifically for the standalone black-box style Subaru BIU / BCM. If your vehicle uses a later fuse-box integrated style module, this listing does not apply.

If you are unsure which version you have, contact us with a photo of the module and its label before ordering.

What Does BIU Cloning Transfer?

The Subaru BIU is responsible for numerous body and security functions and is also an important part of the vehicle's immobilizer system.

Our cloning process transfers the necessary vehicle-specific data from your original BIU into the replacement module. Depending on the vehicle and BIU version, this data may include:

• Immobilizer and security information
• Registered key information
• VIN / vehicle identification data
• Vehicle coding and configuration
• Factory option and customization data
• Other vehicle-specific information stored within the BIU

When the original module is readable and the replacement is compatible, this allows your existing vehicle and keys to recognize the replacement BIU without performing the normal replacement-module programming procedure.

Supported Subaru Vehicles

This service covers many standalone black-box Subaru BIU / BCM modules found in:

• Subaru Legacy: 2005–2014
• Subaru Outback: 2005–2014
• Subaru Forester: 2009–2018
• Subaru Impreza: 2008–2016
• Subaru Impreza WRX / WRX STI: 2008–2014

• Subaru Crosstrek / XV Crosstrek: 2013–2017
• Subaru Tribeca / B9 Tribeca: 2006–2014
  

Important: Subaru changed BIU designs throughout these model years. Compatibility is determined by the module type and part number, not by vehicle year alone.

If your module is integrated into the interior fuse box rather than being the standalone black-box style BIU, this listing does not apply.

Service Details

Data Cloning

We transfer the necessary vehicle-specific data from your original BIU into the replacement module, including immobilizer, security, key, VIN, coding, and configuration information whenever applicable.

Part Number Matching

For best results, the original and replacement BIU part numbers should match exactly.

If you are unsure whether your replacement module is compatible, contact us with clear photos of both module labels before purchasing.

Plug-and-Play Replacement

Once successfully cloned, the replacement BIU is ready for installation and will function as a plug-and-play replacement in most applications, without additional immobilizer or key programming.

Your existing keys are typically retained because the original vehicle-specific security data is transferred to the replacement module.

Fast Turnaround

Once we receive your modules, the cloning service is typically completed and shipped back the next business day.

Important – Please Read Before Ordering

Both Original & Replacement Modules Are Required

You must send us BOTH your original BIU and a compatible replacement / donor BIU to perform this service. No physical module is included with this listing.

Your original BIU is used as the source for the vehicle-specific data, and the replacement BIU is the module that will be programmed with that data and returned to you for installation.

The original BIU must contain readable vehicle data. Modules with severe water damage, corrosion, fire damage, circuit-board damage, or corrupted memory may not contain recoverable data.

For best results, the replacement / donor BIU should have the same part number as your original module. If you are unsure about compatibility, contact us with clear photos of both module labels before ordering.

Please clearly mark the modules ORIGINAL and DONOR and include your order number with the shipment.

Common Reasons for Subaru BIU Replacement

This cloning service is commonly used for:

• Car will not start after installing a used BIU / BCM
• Immobilizer or security light problems after BIU replacement
• Water or flood damage to the original BIU
• Corrosion or internal electronic failure
• Failed power windows or door locks
• Windshield wiper or lighting problems
• Keyless entry / remote-related faults
• Multiple body electrical problems caused by a failed BIU
• Replacement of a damaged BIU without having to reprogram the vehicle's existing keys

Please note: Cloning will not repair unrelated electrical or mechanical problems with the vehicle. The replacement module must be physically functional and compatible with the vehicle.

Have Questions?

Not sure whether your Subaru uses the standalone black-box BIU covered by this service?

Contact us before ordering with your vehicle year and model, original BIU part number, and a clear photo of the module label. We can help determine whether this is the correct cloning service for your application.
