Take it you've tried locking/unlocking the door several times from the key/fob as it sounds to me like it's deadlocked itself.spray a load of wd40 into the lock mech as if they don't get used much they sieze up.only other solution is unfortunatley to force it somehow.have a look on the opposite side door to see how the catch is held in,usually two torx bolts,you maybe able to get behind it too see where the fixings go and possibly grind or tap out the receptors.try to restrict the damage to the door as it will be far cheaper to repair then damage to the inner arch.good luck mate.
