Locked keys under hood, alarm engaged

have you located and tried the emergency trunk release cable?

You should be able to reach up under the front bumper and locate the emergency release cable. Don't be to gentle, just move the plastic on the bottom of the car away from the bumper and reach you hand up there. It will be on the passenger side. Between the headlight and the middle of the bumper.

The more traditional way to reach the emergency release cable is to remove the passenger front tire, remove three or four plastic rivets from the front upper side of the wheel well liner and look for the loop on the steel cable near the back of the headlight tray.

I hope this helps.

BTW: if you ever remove the bumper cover, the take the opportunity to relocate the frunk release cable so you can reach it from the tow hook hole. Then it's easy as pie to pop open the front trunk. I even did the same with the rear cable by locating it under the driver side bumperette.

As mentioned, we don't have the tools to remove the front tire.
We tried to remove the plastic rivets to bend the wheel well liner enough to stick out hand in, but we were afraid to break it. We were successful in pulling back the middle part, but the rivet didn't want to come off.

We've found a hole in the bottom of the car, but that only led to the back of some radiator.

We've tried to put +12V DC on the terminals of C3 with a bunch of Alkaline batteries placed in series. It didn't work either.
