MasterLock 3KA3221 #3 Padlock Keyed Alike

Using the MasterLock 3KA3221 padlock is easy. First, find a suitable hasp or loop where you want to secure your item. Insert the shackle through the hasp or loop and then close it. To unlock, simply insert the key into the cylinder and turn it. When using the padlock, make sure the shackle is fully closed to ensure maximum security. Don't force the key if it doesn't turn smoothly, as this could damage the lock. For maintenance, keep the lock clean and dry. If it's exposed to wet conditions, dry it off as soon as possible to prevent rust. You can also apply a small amount of lubricant to the keyhole and shackle occasionally to keep the lock working smoothly.
