I locked keys in the van how can i get it open with out calling sombody to open it

I'm not sure if the 2007 model would have Onstar, but they can remotely unlock your car if you call them. If that fails, id try the old coat hanger trick to hit the unlock button if its accessible.

Call the police. They can put a jimmy down the window and pop the lock for you.

Before 3 months i had a problem with my Renault clio's locks. I can't unlocked with the remote central locking. I searched in the Internet how can solve the problem. I found some tips for similar problem - http://safekey1stllc.com/7-things-that-you-need-to-know-about-door- locks/. I hope to be helpful for you.
