many with dead battery have hard time opening the front trunk. This has happen to me once. as a result of this experience, I made (I believe you can purchase fully built up unit) a connection into the cigarette lighter socket. Most cars have this socket active with or without the ignition switch.
Most likely, there's plenty of thread here and in other forums. This is what I did.
I have many useless cell phone car chargers. I took one apart, and removed the guts and soldered wires to the two contacts.
went to Radio shack and purchased male/female connector pair and soldered the battery tender wires to a connector.
On the cigarette lighter adapter side, soldered the mating connector to the wires.
This allowed me to "charge" overnight the battery without the need to open the trunk. My car is 01 so the trunk opens with a switch. I would had to dig behind the front wheel well for the emergency cable. but with the cigarette adapter, no need.
if the battery is dead to below some voltage, the battery tender would think that the battery is shorted and will not energize the wires.
in this case, I had an AC to DC adapter 2A at 12VDC and connected it to the lighter adapter for few hours and then switch to battery tender.
Since my car is my daily drive, the battery tender is connected to my other car sleeping in the garage for months at a time. That car starts up strong every time.
Tad.
