Dry graphite powder is great for lubricating small metal parts like locks since it's not oily or sticky and lasts for longer than liquid lubricants. It's simple to use and is suitable for use on sliding doors, garage door tracks, and hinges for doors. Master locksmith Shawn Fago recommends using a pencil-like graphite lubricant designed specifically for lock cylinders.
Liquid lubricants are more effective than graphite powder particularly in humid climates. Silicone lubricants are resistant to water and won't attract as much dust and dirt as other types of liquid fluids. They work well in both low and high temperatures. However, some silicone lubricants could cause buildup over time and can be displaced by other lubricants that you've used.
Teflon oil can be an ideal substitute for silicone lubricants, as they are long-lasting and don't attract dust or dirt. They're also ideal for cold conditions, since they can help prevent ice accumulation inside the lock.

If not, loosen the screws that hold the latch body and adjust it upwards or downwards until the latch is able to catch the latch's hasp with a tight snap when the door is closed.
Sometimes, the latch can be difficult to close due to a worn-out or damaged cylinder. It is necessary to replace the cylinder if the worn cylinder is making it difficult to turn the key. It is important to choose a new cylinder that is similar in size to the old one and has the same keyway, so you can easily replace it by removing the two halves of the lock to one side and inserting the new cylinder.
