When it comes to maintaining the functionality and security of a modern vehicle like the Hyundai Tucson (2016–2020), even seemingly minor components such as door lock actuators play a pivotal role. The Rear Right Door Lock Actuator Latch, identified by part number 81420-D3000, is a critical replacement part designed to restore seamless operation to the door locking mechanism. Tailored specifically for the Tucson’s rear right door, this actuator ensures that the latch engages securely, preserving both convenience and safety for occupants.
Key Parameters and Compatibility
The 81420-D3000 actuator is engineered to meet OEM specifications, guaranteeing precise compatibility with Hyundai Tucson models manufactured between 2016 and 2020. Constructed from a combination of durable nylon and corrosion-resistant metal alloys, the component is built to withstand repetitive use and exposure to varying weather conditions. Its design integrates seamlessly with the Tucson’s existing electrical system, ensuring reliable communication with the central locking module. Users have noted that the actuator’s plug-and-play installation simplifies the replacement process, with one stating, “The fit was spot-on, and it synced with the car’s electronics without any hiccups.” Another highlighted its resilience, mentioning, “After a year of daily use, the lock still engages as crisply as it did on day one.”
Installation and Performance
While the actuator is marketed as a direct replacement, some DIY enthusiasts have emphasised the importance of technical familiarity. The process involves removing the door panel, disconnecting the old actuator, and aligning the new unit with the latch assembly. A common observation among users is that “having the right tools, like trim removal kits and torque drivers, makes the job smoother.” Those without prior experience might find the wiring connections slightly challenging, though detailed online tutorials specific to the Tucson model have proven helpful. Once installed, the actuator’s performance is consistently praised. Drivers report “a noticeable improvement in locking speed” compared to worn-out units, with no lag between pressing the remote and hearing the definitive click of the latch.
Durability and Design Considerations
Hyundai’s original actuators are known for their longevity, and the 81420-D3000 replicates this reliability. The nylon gears, a focal point in many aftermarket actuators prone to wear, are reinforced to resist stripping—a feature appreciated by owners who’ve faced premature failures in non-OEM alternatives. “The materials feel robust, not like the flimsy substitutes I’ve tried before,” remarked one user. Additionally, the actuator’s sealed housing provides protection against moisture ingress, a critical factor given the Tucson’s susceptibility to door seal wear over time. However, a small number of users mentioned that “the actuator’s motor emits a faint hum during operation,” though this is described as no louder than the factory unit and doesn’t affect functionality.
User Experiences and Practical Insights
Feedback from Hyundai Tucson owners underscores the actuator’s role in maintaining vehicle security. One driver shared, “My rear door occasionally failed to lock, which was a safety concern. This part fixed it immediately.” Another noted the importance of diagnosing the issue accurately before replacement, as “intermittent locking problems can sometimes stem from wiring faults rather than the actuator itself.” For those uncertain about DIY repairs, professional installation is recommended to avoid misalignment of the door latch or accidental damage to the door card clips.
In summary, the Rear Right Door Lock Actuator Latch (81420-D3000) stands out as a dependable solution for Hyundai Tucson owners seeking to restore their vehicle’s locking system to factory standards. Its precise engineering, compatibility with 2016–2020 models, and robust construction align with the expectations of drivers prioritising longevity and OEM-level performance. While the installation may require patience for novices, the results—a responsive, reliable lock mechanism—reinforce why this component remains a trusted choice for maintaining the Tucson’s integrity. For those experiencing erratic door locking behaviour, this actuator not only resolves immediate issues but also contributes to the vehicle’s long-term reliability, ensuring peace of mind on every journey.
