Detailed Description

This Aisin tailgate lock is engineered for select Lexus RX applications, including 2007-2009 Lexus RX350, 2006-2008 Lexus RX400h with Power Back Door, 2005-2006 Lexus RX330, and 2004 Lexus RX330 with Power Back Door. If you are replacing a failed rear latch or lock actuator on a Lexus RX350, RX400h, or RX330, DLT-140 provides the OE-style configuration needed for proper tailgate operation. This part cross-references Toyota/Lexus OE numbers 69350-48030 and 69350-48031 for the same application.

What It Helps Fix

• Rear tailgate or liftgate that will not lock or unlock
• Power back door operation that stops responding
• Intermittent actuator movement at the rear hatch
• Fault codes or electrical issues tied to the tailgate lock circuit
• Broken or worn lock mechanism in the rear door assembly

Installation Notes

Verify the vehicle’s year, model, and power back door configuration before ordering. This part uses a 9-pin connector layout, so connector match and harness condition should be checked during replacement. Confirm the existing lock assembly and OE reference numbers before installation on Lexus RX350, RX400h, or RX330 applications.

Quality Assurance

Aisin supplies OE-manufactured components, and this tailgate lock is built to match the original equipment application for the listed Lexus RX vehicles.
