Cheapest/ least damaging way to break into my own car?? Is there any other way?

I have a 1995 lexus sc300, they are known for having issues with the handle/latch mechanism. Well about 4 days ago my passenger side door quit opening from the outside but will still work from the inside, no big deal i thought, ill fix it soon....well the same exact thing just happened to my driver side door....quite a hidiously timed series of events. My jaw dropped in horror as i realized what happened....anyways The problem i think is with the actual mechanism that the handle uses to open the latch, not with the lock mechanism so Im pretty sure a locksmith cant do anything for me. I have the keys and both the keyless entry and manual key turn actually work as i can see the latch go all the way over on both doors when unlocked. I can pop the trunk since i have the keys and access it but the back seats dont fold down to give access to up front. What can I do???
