Fitment includes many C/K-series and light-duty models where the OE used part numbers 16631626, 940-103, 16602474, or 940103. Exact compatibility depends on model year, door style, and factory options, so checking your vehicle's OE part number is essential.

How does this replacement latch restore door function?

When a factory latch fails, doors may not close securely, may rattle, or handles won’t engage. Installing this YCT assembly returns reliable catch-and-release action, restores proper handle linkage response, and eliminates play or intermittent locking issues caused by worn internals. It’s designed for straightforward mechanical replacement with existing linkages and fasteners.

• Reestablishes secure door closure and alignment
• Restores interior and exterior handle operation
• Reduces door noise from loose or worn latching components
• Works with original mounting holes and linkage points

What should I check before purchasing and installing?

Confirming fit is the most important step. Match the OE part number on your old latch and compare the photos to ensure the replacement’s shape, cable/rod attachment points, and mounting locations align with your door. Also inspect electrical connectors if your vehicle has power locks—this latch is primarily a mechanical assembly so wiring compatibility should be verified.

• Verify OE numbers: 16631626, 940-103, 16602474, or 940103
• Compare your current latch photo with the product image
• Check for power lock connector presence and shape
• Have basic tools ready: screwdrivers, trim tools, ratchet set

How straightforward is installation for a DIYer?

Installation is typically a moderate DIY job if you have basic automotive repair experience. The procedure usually involves removing the door panel, detaching linkage rods and electrical connectors, unbolting the old latch, and fitting the replacement. If you’re unsure, a professional or an experienced friend can complete the swap in about an hour.

• Requires door panel removal and access to latch bolts
• Handle linkage rods must be reattached carefully to avoid misalignment
• Test mechanical operation before reassembling the door panel
• Seek professional help for power lock wiring if needed
