2006-2007 Impreza & 2006 9-2X Keyless Entry Module: Programming, Problems, and Replacement

Symptoms of a Failing Keyless Entry Module

When the keyless entry module begins to fail, the symptoms are usually straightforward and related to the remote functions. You will likely notice one or more of the following issues:

• Key Fobs Stop Working: The most common symptom is that the remote lock, unlock, and panic buttons on all of your key fobs suddenly stop functioning, even after replacing the fob batteries.
• Intermittent Operation: The remotes may work sporadically. You might have to press the buttons multiple times or get very close to the vehicle for it to respond.
• Inability to Program New Remotes: If you try to program a new or existing remote to the vehicle, the procedure will fail, and the system will not recognize the fob.
• Whining Sound from Door Locks: In some Subaru models, a whining sound from the door lock actuators can occur due to an electrical issue, which could potentially be related to the control module's signals.

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

While there are no recalls or TSBs that specifically target the keyless entry module itself for the 2006-2007 Subaru Impreza or 2006 Saab 9-2X, there are several important related service campaigns for these vehicles.

Recalls

• Takata Airbag Inflators: A major series of recalls affects both the Impreza and the Saab 9-2X. The passenger frontal airbag inflators can rupture during deployment, causing serious injury or death. This is a critical safety repair that should be performed by a dealer immediately, free of charge. Numerous recall numbers have been issued for this problem, including NHTSA campaigns 20V001000, 20V002000, and 16V358.
• Front Lower Control Arm Corrosion: For vehicles in salt-belt states, a recall (NHTSA 11V464000) was issued for corroding front lower control arms that could break and cause a loss of vehicle control.
• Pinched Wiring Harness (2006 Impreza): A recall was issued for some 2006 Impreza models where a wiring harness could be pinched by a seat mounting bolt, potentially disabling the passenger airbag or causing a fire.

Technical Service Bulletins (TSBs)

Subaru has issued general TSBs about key and immobilizer information, such as #01-168-09R, which provides details on obtaining replacement keys and immobilizer codes. Another TSB, #07-182-20R, discusses a potential whining sound from power door lock actuators, which could be misdiagnosed as a module issue.

Programming and Immobilizer Information

This is the most critical area of concern when replacing this module. The keyless entry module is NOT linked to the engine immobilizer. The immobilizer system, which prevents the engine from starting without a correctly chipped key, is a separate system. Therefore, replacing a faulty keyless entry module will not prevent your car from starting with your existing keys.

However, your key fobs (the remotes for locking/unlocking) must be programmed to the new or used replacement module. For the 2006-2007 Impreza, there are conflicting reports on whether this can be done at home. Some sources provide a DIY procedure, while others state it requires professional tools.

• DIY Programming Procedure (Subaru Impreza): A commonly cited method involves sitting in the car, closing all doors, and cycling the ignition key from the 'LOCK' to 'ON' position 10 times in 15 seconds. The horn will chirp, signaling entry into programming mode. You then open and close the driver's door and press a button on the remote.
• Professional Programming (Saab 9-2X and some Subarus): For the 2006 Saab 9-2X, sources state that there is no self-programming capability and that an automotive locksmith or dealer must program the remotes. This may also be true for some Impreza models, as several sources indicate that diagnostic equipment is required.

Buying a Used Vehicle Access Control Module

A used OEM module is a cost-effective solution for a failed unit. Since these modules are not tied to the immobilizer, they are excellent candidates for recycling. Here’s what to look for:

• Verify the Part Number: The most important step is to match the part number exactly. The correct Subaru part number is 88035FE190. The equivalent Saab part number is 32010763.
• Confirm Transmission Type: The provided information states this module is for Manual Transmission vehicles only. While search results do not elaborate on the reason, it is a critical compatibility point. Do not purchase this module for a vehicle with an automatic transmission.
• Physical Inspection: Check the module's casing for any signs of water damage, corrosion on the pins, or physical cracks. The module is typically located in the center of the dash or under a rear window, where water intrusion is less common but still possible.
• Source and Warranty: Purchase from a reputable seller that offers a warranty. This protects you in case the used module is also faulty. Used modules are readily available for $25-$75.
