Use Quality Keys: Keys should be cut precisely and in good condition to prevent them from getting stuck or breaking in the lock. If you notice difficulty in turning the key, it may be time to replace it to avoid damaging the lock mechanism.

Install Weather Protection: Locks exposed to rain, snow, or extreme heat can deteriorate more quickly. Utilizing weatherproof covers or installing the lock in a sheltered location can extend its life and maintain its performance under various environmental conditions.
