Hmmm... no drilling would be required if simply unlocking the door. All you'd have to do is use a plastic prybar set (to prevent scratching the paint), and then carefully pry up and remove the outer door trim. From there it would expose a gap between the door glass and the door shell, so you could look down and find the part of the lock mechanism that you hook onto with a coathanger or such. It's pretty easy. I've even used this method to help neighbors who have locked their keys in their car.
Once you have access to the interior of the car, you can also pop open the trunk by accessing the vacuum lines running under the right side rocker carpet, and introducing suction to the yellow tube with a green stripe on it. But, you can simply remove the outside door handle and take it to get a key made and then use that key on the rest of the car (assuming the locks all match--on my car neither door lock matches, and they also no longer match the ignition switch, even though they are supposed to).
This really shouldn't be that difficult. If I had access to your car I could probably get inside and then have the door handle removed for taking into a locksmith in about a minute.
