There are a few options. If the trunk and door locks take the same key, take one of the door locks out and take it to a good locksmith. They can cut you a new one. You can also drill out the lock, using a progressively larger bit until the lock bar can be taken out. You can pry, rip and pull the lock out....at the same time probably destroying the trunk lid. The only other option I can tell you, is to remove the back seat. If you're lucky, there will be enough room for you to crawl into the trunk area enough to reach the lock mechanism so that you can remove it and open the trunk.
The door/trunk key costs a few dollars. The ignition key, which must be programmed, costs around $50.
The rear "trunk" (decklid) release mechanism is an option, if equipped, and is located on the right side of the dash protrusion on the dash. It will be a switch that shows an opening "trunk". If this switch is not there, then the car was not equipped with rear trunk release. If you are trying to get into a Fiero trunk that does not have a decklid release mechanism or a broken one, and you have lost the keys, then you will have to actually break into the car to open the trunk. Typically, if the outer key switch is remove, you can insert a long screwdriver into the hole and pop the trunk lock.
