Locked light is on and door is locked

Try putting the oven in self clean cycle as if you were going to clean it then shut the cycle back off. sometimes that will reset things and gain you access to your oven vault. Outside of that you could try unplugging it or turn off the breaker for 15-30 minutes. If that doesnt work you may need to call a tech and have the door lock mechanism checked. As long as the oven is cool it should open. If it has a lever that you have to slide over to lock the door, sometimes people get a little antsy and try to slide the lever over b4 it is cool enough to open, bending the lever. If this is the case try sliding the lever to the closed position (usually it won't go all the way over) if so give it a little pressure to try and straighten it back out. (I said all that without a drop of rum!) Try reseting it turn off power ect.. as mentioned above. Then if all elese fails abandon ship and call a tech.
