What is wrong with only depending upon the deadbolt? Seems like a good locking method to me.
If you decide to try removing the remaining screws there's a couple things I would do. Spray some WD-40 on the screws and general area. There are better penetrating oils than WD-40, but WD-40 is fairly benign in that it won't attack most materials, doesn't have an obnoxious smell, and any residue cleans off fairly easily. Let it soak for days if you have the option.
Before you try to remove the screws give each screw head a few good raps with a small hammer. The jarring of the screws often helps to break loose any corrosion. If the screw heads are recessed then use a proper sized hex driver bit from a multiple bit screwdriver. Fit the bit into the screw head and rap on the hex end. You may need to hold the bit with needlenose pliers for striking.
If the screw starts to turn out it is best to use a back it off a little and screw it back in method. That allows the threads to clean themselves as the screw moves in and out a bit. If you try to just back the screw out completely the corrosion can bind the screw threads and cause it to catch and break.
Use a good quality screwdriver designed for the fastener style. For the most part Stanley is not an example of good quality.
Good luck. vic
