Lever cable is broken. You have 2 options. Spray some lube it the lock cylinder and start working the key in and out, keep spraying lube in once in a while. This can loose up the tumblers in the lock and if the springs are still good, eventually it will open. The next option is to pull the rear seats and go in and release the latch with a screw driver. Then replace the lock.
