Nissan Micra - Both Keys Failed - theoneandonlyfred

My girlfriend went sailing a couple of nights ago and her car key got wet. She drove home but when she went to use the key yesterday morning it did not work and she couldnt get in. Her spare key has never worked. I have read the forums and got into the car through the secret keyhole on the passenger side. The ignition failed to start (the dashboard showed the airbag off light and at some stage the battery light showed). I tried to jump start with no avail, and the fuses are all in tact. As the spare key does not work I am unable to open all the doors which it says is required to go through the re-programming procedure for the keys. Can anyone help please before I am left with having to tow the car to the Nissan Garage and pay them?
