My driver side door won't open since I had someone change the handle and lock..how can I get it to open up..the security system shut it tight and won't allow me to pull it open..

I guess the 'someone' wasn't a 'paid professional' that you can bring it back to? Now it will probably be the most cost effective method- bring it to a shop that is familiar with that brand. They may have no choice but to break or damage the panel to get it open , but you might get lucky!
