Latches - Latches are basic locking systems for heavy duty trunks. They make it easy to access anything that is stored inside the trunk, but they don’t deter other people from opening the chest.
Padlock - A padlock can securely lock items inside your heavy duty trunk. The only ones who can access a padlocked trunk are those who have the keys to it.
Key Locks - Advanced heavy duty trunks come with quality key locks, so there is no need to purchase a padlock. The key locks are often built-in. The most common types of key locks are the traditional and the cylinder. Cylinder locks are pick-proof, but they are expensive. Traditional locks may be cheaper, but they can be picked.
