If the lock is stiff, use a lubricant like WD-40 or graphite powder. Spray or apply it into the keyhole and work the lock back and forth to distribute it. If the lock is a spring bolt (not a deadbolt), you can try sliding a credit card between the door and the frame just above the lock.
Lubricate: Apply a lubricant like WD-40 or graphite spray around the key and lock. Allow it to sit for a few minutes. Wiggle the Key: Gently wiggle the key back and forth while pulling it out.

One simple lock picking technique involves sliding a rigid card (like a credit card or driver's licence) between the door frame and latch, then quickly moving the card upward to force the latch upward and retract it into the door. Repeated tries at different angles eventually connect to lift the lock successfully.
Generally speaking, a screwdriver is a good tool when trying to open a lock, but not by itself. Because of its shape, it can help turn the lock, but not reach where the pins are and jiggle them free. So you'll also need to use another tool, like a "rake" or other small tool to rake against or "jiggle" the pins.
Will WD40 help a swollen door? WD-40 can help reduce friction and might loosen up a swollen door temporarily. But it's not a permanent fix since it doesn't tackle the root issue, like moisture or humidity. For a long-term solution, try drying out the door or sanding down the swollen areas.
Use Graphite Powder
Graphite powder is an excellent lubricant and a great way to fix a lock that is becoming difficult to unlock. Powdered graphite lubricant can be bought in small bottles made of soft plastic with a nozzle, meaning it is easy to squirt a small amount of lubricant into the lock.

Humidity is usually the culprit for sticky doors since high moisture levels cause the material to expand, pushing the door into the frame. This only happens in wooden doors, but steel and fibreglass doors tend to stick, too, if the wooden door frame swells.

Coat your key in graphite and insert it into the keyhole. The graphite will act as a lubricant to help unjam lock tumblers that may have become clogged with debris over time.
To unseize a lock your need plenty of WD-40 (or something similar, but don't use things such as 3 in 1 oils, PTFE, or Graphite). Key goes in but does not turn: Using the WD-40 with the straw attached to the nozzle spray a large dose into the lock and leave for a few minutes.
What's the best lubricant for your lock? When choosing the best product to lubricate locks, dry lubricants like graphite powder and PTFE lubricants are best. As mentioned above, oil-based products can attract dust and dirt which can damage the delicate internal mechanism of your lock.
