 If the lock cylinder is not turning smoothly, it may be due to accumulated dust or rust inside.

 If you have experience with lock picking tools, you can try using lock picking tools (such as a crowbar or lock Hook) to open a cylinder lock. First, insert the crowbar and apply gentle pressure while simultaneously using the lock hook to turn the lock cylinder. This method requires some skill and experience and is recommended only when there are no other options.
