I suggest calling a locksmith. The cost of a locksmith is usually less than damage you might do trying to get in the car yourself. They are (usually) trained and have proper tools to do it right, without damage.
AAA has lockout service, if you're a member...but tow-truck drivers can be a bit impatient/over-enthusiastic/under-trained/ somewhat-lacking-in-finesse and can cause extensive damage, especially
if electric locks are involved.
(Ask me how I know this...)
