You should only press the keys on a saxophone hard enough to make them close.
And you should keep your fingers directly upon the keys in most situations (for some notes you must lift them).
If you feel like you CANNOT play a note without pressing the keys down very strongly, then you probably have a leak.
If that is the case, take your horn to a repair person. They will use a ‘leak light’ to check for leaks.
