This is basically the heart of your door lock. You stick your key in, it turns, and mechanically opens or locks the door. It's a pretty simple idea, but it has to be precise. Some have provisions for central locking too, meaning the motor for power locks works through it. Think of it as the first line of defense against someone getting into your car. It's part of the door latch mechanism, keeping everything securely fastened. It’s what physically connects your key to the action of opening the door. It works along with the latch and striker to hold the door closed, and also releases that hold when you unlock it. Well, pretty obvious really. If it fails, you’re likely stuck outside your vehicle, or worse, your door won’t stay shut while you’re driving. You’ll notice if it’s starting to go bad because your key might not turn smoothly, or it might feel sticky. Sometimes the key will turn, but the door won’t unlock, or vice versa. It’s a crucial safety and security item. You can find replacements online, somewhere like Fixparts Online has a good selection, but it’s something you really want to address promptly. A failing lock cylinder isn't just an inconvenience, it could leave you vulnerable. Designed for durability: Lock Cylinder (MPN 107837167JA) includes a 12-month warranty!
