It looks like some one tried to break into this Jeep at some point. The passenger side door lock was destroyed by a screw driver and the paint around it is marred with deep scratches.
To start the process of replacing the door lock cylinder you will need some basic tools. Pliers, flat head screw drivers, a hammer, and possibly a rotary cutter. It is best to by a full replacement lock cylinder from a dealership for $50 since the smallest notch in the wrong place can prevent the cylinder from turning.
Here is the uninstalled cylinder up close.
Start by removing the C clip and actuator arm on the back of the cylinder.
Remove the metal cover the holds the cylinder in place. You will have to destroy it when removing it since it is crimped on. The replacement kit comes with both chrome and black covers.
The cylinder should now come free. Tap with a hammer from the back gently if it does not slide out.
Kbrawlz on YouTube provides an excellent guide on how to transfer the pins and springs to the new cylinder.
Transfer all of the pins and springs over to the new cylinder in the same order and reassemble. Be sure to grease the cylinder with the include white lithium grease and test your key to make sure it turns easily. I had to grind the lock pins just a tiny bit to make it all move smoothly.
Install the new flappy door.
Carefully crimp on the new cover and you are done! Reinstall the door lock into your door.
