Left Front Door Key Lock Cylinder for JAC JS3 S3 T40

Your left front door lock should turn smoothly every time you reach for your car keys. This replacement cylinder fills that gap when the original mechanism wears out or rusts shut. It restores secure entry to your JAC JS3, S3, or T40 without demanding a full door panel removal. You get steady operation exactly where it matters most on the driver side.

Keep the new cylinder running free by applying dry graphite spray during the first week. Swap this unit out when your key binds or turns with excessive play. Check your vehicle build date before mounting. Early factory runs often use different core cuts that require a precise match.
