What it does:
Placed inside the door handle mechanism over the lock cylinder, this spring provides the return (spring-back) force that pushes the cylinder back outward after unlocking or locking. It works in compression, acting against a C-clip and washer to maintain proper tension and smooth operation.

Why replacement matters:
The original spring can weaken, lose tension, or corrode over time, leading to sticky or loose door locks, sluggish handle action, or failure to return properly. This OE-Match version restores the correct spring strength and ensure reliable, smooth door lock operation.

Where it fits / Location & position:
•  Fits inside the door handle / lock cylinder assembly
•  Sits over the lock cylinder inside the handle, compressed between clip and washer for proper tension
