66 cuda door stuck help

It may not be the door lock it maybe just stuck my old vals back doors liked to do that if i shut them too hard lol Just give it a good kick see what happens
Deff shut it hard by accident. Don't want to kick it, this car is completely restored besides a few seat covers. Just want to fine a option that works best. Tried pulling the lock and raising the door handle, tried using the key and also tried holding door handle from inside and putting my shoulder into it.
