Product Description

Rear Left Door Lock for Tesla Model 3/Model Y (-2023) | 1500674-91-B

1. Core Function Description

As a vital component of the rear door security system for Tesla Model 3 and Model Y (up to 2023), this premium brand-grade rear left door lock is engineered to match original factory specifications, with core functions focusing on "secure locking + seamless integration + rugged durability":

Reliable Locking & Unlocking: Equipped with a reinforced cam-lock mechanism, it ensures the rear left door stays securely locked during driving, parking, or rough terrain. It supports smooth operation via Tesla’s key fob, interior switches, or mobile app, with a rapid response time (≤0.6 seconds) for convenient access.
Vehicle System Integration: Communicates in real-time with the Body Control Module (BCM) to transmit lock status, enabling coordinated functions such as activating the vehicle’s anti-theft system when locked or triggering "door ajar" alerts on the dashboard if not fully closed. This integration maintains consistent security and user feedback.
Environmental & Wear Resistance: Built with corrosion-resistant materials and sealed components, it withstands water, dust, and extreme temperatures. This protects internal gears and electronics from damage, ensuring long-term performance in rain, snow, or high-humidity environments.

3. Fault Judgment (Signs for Replacement)

Replace this rear left door lock immediately if you notice the following symptoms, indicating wear or failure:

Lock/Unlock Failures: The door does not respond to key fob, app, or interior commands, or requires repeated attempts to operate. This may stem from a faulty motor, worn gears, or damaged wiring.
Abnormal Noises: Grinding, squeaking, or clicking sounds during operation, caused by debris in the mechanism, misaligned components, or worn-out parts.
Dashboard Alerts: Messages like "Rear Left Door Lock Malfunction" or "Check Door Lock" on the display, signaling a loss of communication with the BCM.
Insecure Locking: The door can be opened from the outside or inside despite being "locked," indicating a failed locking pin or weak spring.

4. Advantages of Premium Brand-Grade (vs. Generic Products)

Advantage Dimension	This Premium Brand-Grade Lock	Generic Products
Material Durability	304 stainless steel housing and hardened steel components; resistant to rust and wear.	Low-grade steel or plastic; prone to corrosion and breakage within 1-2 years.
System Compatibility	Seamless integration with Tesla’s BCM; no false alerts or system errors.	Often causes dashboard glitches or fails to sync with vehicle security systems.
Operational Reliability	Consistent performance in extreme temperatures; anti-jam design prevents sticking.	Malfunctions in cold/hot weather; high risk of jamming, requiring forced entry.
Longevity	Tested to 80,000+ cycles; designed for extended use.	Fails within 20,000-30,000 cycles; frequent replacements needed.
