Lawdog, I am failing to find why you have a problem with the key lock...if you dont want to use it, then dont....The gun will not lock itself....Just forget it is there...but that lock NEEDS to be there for the purpose of takedown...the button needs to be pushed in with the finger to rotate the takedown lever...but that will not 'lock" the gun...
THE only way to lock the gun is with the KEY, and you have to insert the key, depressing the lock about 1/4 inch, and then turn it 90 degrees...definitely not something that happens by accident.
