Tips from an Automobile Locksmith: How to Lubricate Your Car Door Locks Since these are susceptible to various problems, including rusting and jamming, a key aspect of general car maintenance is caring for the car door locks. An important, often overlooked, part of general car maintenance is caring for the car door locks. According to a professional automobile locksmith, car door locks are susceptible to various problems, including jamming and rusting. Keep in mind that among general car cleaning methods, car door locks are probably the most neglected part of a vehicle. This virtually makes sense since they donâ€™t offer a substantial cleaning surface. For you to clean the car door lock or to lubricate it, you will have to access the interior of the locking mechanism, which can get a bit tedious. Tips from an Automobile Locksmith: How to Lubricate Your Car Door Locks: Steps 1 Understand the reasons why car door locks need to be lubricated. Just like any other metallic object, a car door lock is vulnerable to moisture-induced issues such as rusting. In addition, repeated insertions, twists and turns of the key into the locking interface and careless handling by people, make the car door locks prone to impaction of debris along with moisture, sweat and impurities found in the surrounding environment. The most effective way to protect the condition of car door locks against such issues is to thoroughly lubricate and clean them. Locks that are not lubricated are more susceptible to jamming as the grime and moisture tend to get wedged in between the locking components. These types of problems are more common in areas that have low temperatures or high levels of humidity. 2 Learn how to clean your car door lock. Keep in mind that cleaning the car door locks, before lubricating them, is very crucial. Doing so will prevent the
lubricating agent from wedging debris deep within the lock. To access the lockâ€™s interior; wrap a dry cloth around the tip of a small screwdriver and insert this within the car door lock and move it in a circular motion. After, spray or pour a liberal amount of rust-removing solvent on the cloth and repeat the cleaning action. Repeat the steps by cleaning the door lock again with a fresh piece of dry cloth. In colder surroundings, drying the lock with a hair blower is more advisable. This ensures that any ice or salt crystals within the locking interface are removed. 3 Use silicone lubricants for lubricating car door locks. Silicone spray lubricants are well suited for car door locks, according to GS Locksmith. Croydon-based GS Locksmith also stresses the importance of buying a lubricant with a spray straw, such as WD40, since it can be used to lubricate the parts positioned deep within the locking system. In addition, these types of lubricants are impermeable to water and stick to the metallic surface for a longer period of time. 4 Be sure to push the spray straw as much as possible. Start spraying the lubricant in short intervals. Regularly cleaning your locks helps prevent the need for an automobile locksmith. Romford has many specialty stores that sell affordable silicone lubricants.
