Will the key turn in the trunk lock cylinder? Does any thing power up when you turn the ignition ON without starting the engine?
Go under the hood and on the passenger side rear of the engine compartment you will see a thick black cable. That is a positive cable. Pull back the rubber boot and hook the red positive side of a booster or charger there and the black negativ lead to the body. This should give you enough power to unlock the vehicle and open the trunk electrically. Then we can fully charge and test the battery.
Glad everything worked out.
