Question about 1985 Pontiac Fiero
Does your Fiero have a power trunk switch? I had the same problem where I locked the keys in the trunk and the battery was dead. I had a portable car jumper that had a cigarette lighter socket and basically hooked it up through the cigarette lighter in the Fiero. The power flowed from the portable jumper through the car to give it enough power to open the trunk. You could also splice a cigarette lighter cord to a battery and plug it in.
If you don't have power trunk then you may have to drill the lock. I have heard that Fiero's were all wired for power trunks but you had to pay for the "option" to have them put in the switch when they were band new. I wouls also suggest taking off the small trim panel to the right of the intrument cluster and see if there is a power trunk connector there. If there is then you could purchase a power trunk switch to pop the trunk. Unfortunately I own 5 Fiero's all of which came with power trunk so I was never able to verify if that rumor was true. Good luck.

You will have to drill out the lock and replace the lock

There are only 4 ways to open a Fiero trunk. With the key, with the electric trunk release, with a locksmith, and with a big hammer and screwdriver.
Some year Fieros required the parking brake be applied to activate the electric release, some had to be in park, and some of the early models would work just by pushing the button. The ground is through the latch, itself. If anything has gotten on the body portion of the latch and the trunk was closed, like a towel or plastic bag, that prevents the trunk portion from making metal to metal contact with the body striker, the release won't activate. If you can put power to the car, insert a key into the trunk lock, clamp one end of a negative jumper cable to it, and the other end underneath to some part of the frame. Hit the release button. This trick completes the ground circuit directly into the latch mechanism and bypasses the body striker plate.
If this doesn't work, remove the release switch from the dash, unplug it, and apply power with a 9V flashlilght battery to the terminals. You may have to play with the emergency brake handle during these processes.
