Review SUBARU Right Front Door Lock Actuator Oem fits BRZ 2012–2016

The **Subaru 643.SU1B15 BRZ (2012 2016) Right Front Door Lock Actuator** is a precision-engineered component designed specifically for the iconic second-generation Toyota Sports Racing 86 and Subaru BRZ, ensuring seamless operation of the vehicle s power door lock system. This actuator, part of the **13 14 15 model-year lineup**, is crafted to meet the exacting standards of Subaru s engineering, delivering smooth, reliable performance with minimal wear over time. Built with a robust **plastic housing** and reinforced internal mechanisms, it is engineered to withstand the rigors of daily use while maintaining durability in varying environmental conditions, from extreme heat to cold climates.

Its compact yet sturdy design ensures a perfect fit within the BRZ s door panel, minimizing clearance issues and preventing interference with surrounding components. Whether replacing a failed actuator due to electrical wear, mechanical failure, or corrosion, this **OEM-quality or high-grade aftermarket alternative** restores the door lock system s functionality with ease, ensuring a secure and responsive driving experience. Ideal for both professional mechanics and DIY enthusiasts, this part is a critical component for maintaining the BRZ s signature blend of sporty handling and practicality, keeping the door locks operating silently and efficiently for years to come.

### **Pros and Cons of Buying a Subaru 643.SU1B15 BRZ (2012-2016) Right Front Door Lock Actuator (Part #13-14-15)**

1. **Direct Fitment** The part is specifically listed for the 2012-2016 BRZ, ensuring compatibility without modifications.

2. **Reliability** Subaru s door lock actuators are generally durable, and a new one should resolve issues like sticking, failure to lock/unlock, or electrical malfunctions.

3. **Prevents Further Damage** A faulty actuator can strain wiring or door mechanisms, so replacing it early avoids secondary problems.

4. **Ease of Installation** The BRZ s door lock actuator is relatively straightforward to replace, requiring only basic tools and a bit of mechanical skill.

5. **Warranty Coverage** Some sellers offer warranties, providing peace of mind if the part fails shortly after installation.

6. **Cost-Effective Fix** Replacing the actuator is far cheaper than repairing or replacing the entire door mechanism or wiring harness.

1. **Potential Counterfeit or Low-Quality Parts** Some online sellers may offer knockoff or substandard actuators that fail prematurely. Buying from reputable suppliers (e.g., RockAuto, Amazon, or authorized Subaru parts dealers) mitigates this risk.

2. **Mismatched Part Numbers** The **643.SU1B15** designation may vary slightly depending on the year or trim level. Double-checking the exact part number for your specific BRZ model is crucial to avoid mismatches.

3. **Additional Labor Costs** If you re not comfortable with DIY repairs, labor costs at a shop can range from **$100 $200**, depending on location.

4. **Electrical or Wiring Issues** If the problem stems from a faulty wiring harness, fuse, or door control module, replacing just the actuator may not fully resolve the issue.

5. **Limited Availability of OEM Parts** Some sellers may not stock genuine Subaru parts, leading to longer wait times or higher prices for OEM replacements.

6. **Potential for Overpaying** New OEM actuators can be expensive (often **$150 $300 **), while high-quality aftermarket options may offer similar performance at a lower cost.

### **Conclusion**

Buying a **Subaru 643.SU1B15 BRZ (2012-16) right front door lock actuator** is a practical solution if the issue is isolated to the actuator itself. The part is essential for proper door function, and replacing it prevents further complications. However, ensuring you purchase a **genuine or high-quality aftermarket part** from a trusted source is critical to avoid future failures.

If the door lock problem persists after replacement, further diagnostics (e.g., checking the door control module, wiring, or fuses) may be necessary. For most DIYers, this is a manageable repair, but those uncomfortable with mechanical work should consult a professional.

### **Recommendation**

1. **Verify the Part Number** Confirm that **643.SU1B15** matches your exact BRZ model year and trim (some years use slightly different part codes).

2. **Choose a Reputable Supplier** Opt for **OEM Subaru parts** (from Subaru dealers or authorized distributors) or **highly rated aftermarket brands** (e.g., Denso, ACDelco, or local specialty suppliers).

3. **Check for Warranty** Select a seller offering at least a **1-year warranty** to protect against defects.

4. **Budget for Potential Extras** If the issue is electrical, have a **multimeter** on hand to test wiring, or budget for a shop visit if needed.

5. **DIY vs. Professional Installation** If you re experienced with car repairs, proceed with installation yourself. Otherwise, a mechanic can complete it for **$100 $200 in labor**.

**Final Verdict:** This is a **worthwhile purchase** for resolving door lock actuator failures, provided you source the part correctly. A well-maintained BRZ will benefit from this straightforward repair, ensuring reliable operation.
