DOES YOUR MAIL BOX LOCK?
If your lock in the mailbox freezes, it's time to find the lock oil. We recommend that you regularly use locking oil to ensure that it does not freeze. If the lock oil is not enough, you can do the following: Heat your mailbox key with very hot water, wipe the key to make sure that no more water enters the lock. Insert the hot key into the frozen lock - repeat if necessary. Heat your lock with a blow dryer tube. Use an extension cord that can be used outdoors. Do not use: Hot water to thaw the lock. It just leaves more water in the lock, which in turn freezes to ice. Avoid spray products WD40 or other oils - use only locking oil.
