Deadbolt repair versus replacement decision factors
https://extra-wiki.win/index.php/Deadbolt_repair_versus_replacement_decision_factors
When deciding between repairing or replacing a deadbolt, consider the lock's age, damage extent, and security needs. A simple jam or misalignment often calls for repair, but rust, stripped screws, or worn mechanisms in an older lock may make replacement more cost-effective and secure. Also, upgrading to a smart or high-security deadbolt is worth it if your current one lacks modern features or if you're moving into a new home.
