If pried the panel off, you should be able to see an actuator. There is a plate with 2 cables attached to it. If you push that plate counter the cable, it should unlatch. Look at realoem. Com to see structure of the lock- it will help. I had to pull the same trick when I closed that gate with battery being disconnected.
