possibly but i thought it was more complicated then that
heres basicly what can happen.
Remove the spring connectors from the board and body of the egg. find 2 push on connectors for the 9v batterys and therefore reduce the pressure on he door
Gav, Think Lovetone means using pliers just squeeze the connectors gentley to lower them. But i wouldnt as its the batteries pressing on the door that keep it firmly shut. A good bunker dive will open you up and loose batteries and break door leaving you writing another thread in the classifieds asking for a battery door!
