[V8] Battery out of car, locked out again!

[bw at UDel.Edu]

Does anyone know a way to open a V8 that has the battery removed? I've done this 
before and I made a point of leaving it open, but somehow it's locked again.In the 
past, I have gotten half way thru the ski sack opening to attach jumper wires to the 
+ & - cables and used an external battery that then let me use the key in the door. 
I really don't want to do that again! Any other way? The hood is latched and it 
seems slim jims won't fit. How then? Bob
