Infiniti - battery dead, both remotes dead, cannot pop hood!

Bad cable or connection? Clean posts of battery and reseat connectors, follow power cable checking voltage along the way

Please charge your battery with a charger before you fry your charging system. It may need to be replaced. It may be too late for your charging system. When you drain the battery dead, there is still chemical energy left in the cells. If power draw is stopped, the battery will seem to charge itself and work again. In doing so, a part of the capacity is sacrificed forever. If the battery is drained empty more than a couple of times, it's time for a new battery.

To the car, a dead battery is an overload. Some vehicles are designed not to try to fully charge a dead battery. Most vehicles will burn the charging system up trying to do so. Same idea, if this happens much you will need a new alternator and maybe more parts.

I would definitely have the car serviced by a pro shop, with veteran mechanics. Discuss your concerns with the ignition and charging systems, and tell the tech about your power loss event. Symptoms such as this are better fixed before murphy's law kicks in and you are left stranded on the road somewhere. The repairs cost less before everything is destroyed as well.

new batt if it is over 3 yrs old-needs to always be at 12.6 v--its not holding charge well--have it load tested--probly only gettn a surface charge onit-it will fool u

Use the key and put it in the door, the old fashioned way :)

hood lever inside first, then pull up on the hood, it should only come up about 2 inches, then the lever should be dead center kind of behind and below the grille.

Hood latches are cable operated not electrical.you need to have someone push down and pull on hood as you pull release.then lube latch when you get it open

You can jump the car without opening the hood.Jack the vehicle up on the starter motor side.get a jumper battery and jumper cables.with the jumper cables connect the positive terminal of the jumper battery to the positive feed (thats the cable that comes from your vehicles battery) on the stater motor. using the negative jumper cable side, earth the jumper battery on the gearbox or starter housing, preferebly. You can now unlock your car with the remote

Power the car's electrical systems with another car using jumper cables attached at the connection point and a good ground under the hood. That should make the trunk release work.

You did not mention the year, but I am guessing that you have an all-electric trunk release and the car is electrically dead due to the battery cable problem.
If this is the problem, attach another car via jumper cables to the jumper cable attachment point under the hood and a good engine ground to power the car so the lock will work.
