Can you open the center part in the middle of the seats and try to fish the keys out?

hook a jump box or charger to the post in the engine bay. That should get you power

If you hook power to it now it may burn something up depending
on the way the battery distribution block is laying . And it may not
get power to the cabin electronics if you disconnected the big outside
red wire (furtherest left on the battery distribution block)which is what controls the locks anyway.

OP locked his key FOB in the trunk after replacing the battery (which should have power) and therefore needs to get a new FOB, or key, made at the local dealer if he has proof of registration.
The OP in the thread link had his key FOB, which has no physical key, but there was no power for him to open the trunk which others replied on how to use the jumper points in the engine bay to get power.

He said he took the battery out left the key s in the
trunk then locked it in the first post . So no battery in the
car and keys locked in the trunk the best of all possible
disasters.
