You say the button is pushed in? It has a spring that should push it back out. Is the key hole vertical or horizontal? If its horizontal, it's locked. I'd take a rubber or a deadblow hammer and give it a good whack, but if it's unlocked and button in, it should open. Worse case use a 5mm drill bit. It will ruin the lock cylinder, and wafers. You drill thru the lock cylinder and wafers, then drill off the screw holding the actuator tab onto the rear of lock. then the entire cylinder will come out, and you can reach in with a screwdriver and push the tab that opens the trunk. Then send me a key and I'll make you a new cylinder for the lock.
The key hole is horizontal. I can put the key in and rotate it to vertical almost. It's like it can't get to the final full vertical position, off by a hair. I can sort of pull the key out about 1/4" inch when it's in as vertical a position as I can get but I don't want to try pulling the key all the way out in that state. I then turn it back to the locked position.
If I have to do it by a drill method I'll be doing the drill from above the license plate area to try and put something in the hole to trigger the latch. I'm just not sure of the exact spot since it seems folks use a few locations, which I guess all work.
This unlock the trunk process is sort of like Bigfoot. People talk about doing it, but photo evidence of how to do it is not around other than the folks with the PORSCHE reflector covering the trunk release and they show where to drill in that case. But it looks a lot higher than the folks going in just above the license plate description.
