Defective Locks FAQs
Q: My locks freeze in the winter. What can I do?
Lubricate your locks with Master Lock recommended lock lubricant 2300D. Master Lock’s lock lubricant 2300D is specially formulated to not only prevent your locks from corroding, but the formula also prevents moisture from condensing inside the lock, which greatly reduces the likelihood your lock will freeze due to cold weather.
