08 Civic's trunk won't open?

My 2008 civic's trunk won't open. I've tried the manual latch attached to gas latch inside vehicle, I've tried the trunk button on keys.

called honda and they said they'd charge me $700 (yes $700) to "break the locks" and open the trunk.

isn't there another cheaper option?
Added (1). One locksmith told me they couldn't do anything. Haven't tried bodyshop yet though.
