Push button dash

I read on an old thread about the motor being locked if the trans is not in "N" and the park lever down my park lever just flops up and down but "N" is pushed in. The motor is locked but i've been oiling it for a week with no luck. Thoughts on this? Also is this push button system worth fixing or are the junk? If I can make it work then fine but I also thought of a column or floor shift
