First, clean the surface of the screws thoroughly, especially the rusted areas, to facilitate the subsequent disassembly. Then boil a pot of water and soak all the screws in it. After putting them in, soak them again in the boiling water. Finally, reinstall them according to the original steps.

Last time I replaced the plastic cover on the door lock post of my Jetta by myself, and it was quite simple, mainly requiring patience. First, locate the lock post position at the edge of the door, usually covered by a black plastic sleeve over a metal post, which serves as dust and water protection. Use a small flathead screwdriver to gently pry off the old cover—if it's too tight, you might spray some rust remover to loosen it. After removal, clean the metal part to avoid rust, then align the new plastic cover's slot and press it in until you hear a click, indicating it's securely fastened. The whole process should be done gently to avoid damaging the door paint by forcing it. It took me about ten minutes to complete. Now the door opens much more smoothly without the previous squeaking noise. I recommend buying an original part from an auto parts store—good quality and not expensive. Remember to wear gloves to prevent hand injuries. This job can easily be done at home, saving money and honing your skills.

As someone who frequently works on car repairs, replacing the plastic cover of the Jetta's door lock striker is a common task. First, fully open the car door and locate the lock striker on the B-pillar or door frame. Over time, this plastic cover can age and crack. Use a screwdriver to remove the fixing screws (newer models might not require this), then carefully pull out the old cover. After cleaning off any residual adhesive and dirt, align the new cover and push it firmly into place, ensuring it fully snaps onto the lock striker. All you need is a simple screwdriver—avoid using excessive force, as it could deform the metal striker and cause trouble. A common issue is improper alignment of the new cover leading to difficulty in closing the door, so test the door by closing it several times to ensure smooth operation. If you're unsure, it's best to visit a professional shop—their fees are reasonable, and they can also inspect other locking mechanisms while they're at it. Regularly replacing this cover can extend the lock's lifespan and prevent rainwater from entering and causing corrosion. If you attempt it yourself, be careful not to pinch your fingers.

My car is an old Jetta, and I found it hard to close the door because the plastic sleeve was broken. After some research, I realized replacing it was quite straightforward: First, check the lock post position, usually located at the top of the door frame, find the plastic sleeve, and carefully pry off the old one without leaving debris. Clean the metal surface, then align and press the new sleeve into place. The key is not to rush—install it properly and test it once. After I replaced it myself, the door lock operated smoothly, and I didn’t have to spend money on a mechanic. It’s important to pay attention to this part regularly—replace it immediately if it cracks to prevent rust.
