Yes, you can use WD-40 to unstick a lock. Start by inserting the straw nozzle into the lock and spray a small amount of WD-40 inside. Give it a few minutes to penetrate, then try turning the key gently back and forth. If necessary, repeat the process to ensure the lubricant reaches all parts of the lock mechanism. WD-40 helps in loosening rust and debris, making the lock easier to turn.
