Open my trunk, please.

I just got my e46 330i back from the mechanic, but it was dead and I didn't have the key fob (just the valet key). The cherry on top isn't having to get into the trunk, though. The negative terminal was disconnected by my mechanic. Can I crack it somehow?

If you happen to have jumper cables and an additional vehicle on hand, you can power the locks by linking the downer car's battery to the E46 jump points located under the bonnet.

I attempted to connect a portable jumper with a 1250A rating to the wires under the hood, but alas, it was unable to detect the battery, so it remained inactive. I even attempted to overwrite it. It would have worked if the battery terminals were connected, but I'm stuck without a master key fob and the negative terminal isn't connected.

Odd, because I've done the same thing without the battery.

It should work; maybe there's a diesel setting that would be useful, but I'm not sure if you had a good connection with the jump pack.
Do you not possess a key that can start the vehicle? because the e46's boot/trunk key is that one.

You will need to disassemble and remove the right-hand bootlid light if you do not have a key or 12v. To open the boot lid, push the carpet inwards, then locate the cable that operates the latch to the left of the hole. Give it a good tug and the lid will open.
