Opening trunk with dead battery

[JV3]

Hi everyone

Earlier this week the battery in my G70 (Dynamic) was completely drained. It wasn't clear to me how, (or if) the car could be jumped from under the hood. A quick look at the owners manual revealed that access to the trunk with a dead battery requires crawling through the back seat and using the emergency trunk release - conveniently located at the very back of the car.

AAA got the car started and I took it to the dealer. They kept the car for a day and confirmed the battery was fine and that I must have left a door open - I hadn't.

Am I missing something? Can't imagine how much fun it would be to deal with a dead battery while traveling with a trunk full of luggage.

Why couldn't you open the trunk with the key? Is there not a traditional key hole?
Could you possibly open the hood, hook up battery cables to the battery jump terminals and then use the button on the driver door?

Yes you are. You have found the absolutely most difficult way. It’s easy once you realize where under the hood.

Thanks for the response.

I've looked behind the car and don't see anywhere for the key. I assume there's a way to jump the car from under the hood - but I didn't see where.

There are terminals in the engine bay to jump start the car. The positive terminal is located in the fuse box in the top left of the engine bay, and the negative terminal is next to the passenger side airbox.

The owner's manual has a good illustration of where both are located.

I found it in the manual; probably as you were typing! Given where the car was in the garage when the battery died, it was actually more convenient to crawl through the trunk.

I bought a decent booster pack to keep in the car and going forward I'll jump it from under the hood.

I'm just kind of surprised that you can't (AFAIK) use the key to open the trunk.

Me too!! I haven't even looked at mine and my wife is driving it today so I can't go currently look.

I have a 2020 G90 with a dead battery and can’t get in the trunk. Manuel’s are in the trunk. Can I charge under the hood on this model? Thanks

I have a 2014 Genesis Coupe 2.0 RT. battery died on it the other day and couldn't get into the trunk to get my tools. Fortunately the jumper cables were not in the trunk. So my question is, for the 2014 Coupe, is there a way to open the trunk with no power to the car? I have looked all over the back of the car to find a key hole, no luck.

Key is under trunk lip to the right

Key is under trunk lip to the right

I just purchased a 2019 G70 3.3T Sport and there is no manual/mechanical key port on the trunk lip.

Even the owner's manual states:
"When the vehicle battery is discharged or the trunk needs to be opened manually:
1. Fold the rear seats using the seat back folding lever.
2. Open the trunk using the Emergency Trunk Safety Release lever."

Unless someone here has more experience or found something I am not seeing, there is no way to open the trunk if the battery is completely discharged, except for the emergency release which is inside the trunk.

Think about why is it that you'd want to pop the trunk open with the dead battery. Is it to get access to jump start or charge the battery? If so, there is no need to pop the trunk. Genesis provides terminals under the hood for those purposes. See post#5 above.

Other than my GMC Savana, which is a dinosaur, I have not used a mechanical key on any car for at least 10-12yrs. Key cylinders on cars are fast becoming more a security liability than useful feature. Just ask owners of all those Kia/Hyundai lower trim cars that have recent been stolen.

Yes I understand you can jump from the front with terminals under the hood. That's not the issue.

The reason I would want to open the trunk with a dead battery would be because my portable jump starter is in the trunk (I would assume most people keep theirs in the trunk as well). So if I have a dead battery I need to open the trunk to get my portable jump starter to jump start using the terminals under the hood.

The only solution I see (which is not the worst thing but inconvenient) is to fold down the back seats and retrieve the jump starter that way.

Again, unless I'm missing another way to get the trunk open with a discharged battery.

Fair point.

We actually had to do it twice. Both times was when we working working on the cat back exhaust. I disconnected the battery to spot weld the pipes and hangers in position and my son shut the trunk lid. He climbed in thru the back seat and pull the tab. He's young and a lot more flexible, but I probably could do it fairly easily too.

I think that's the only way. I checked inside the fuel filler cavity, and there's no emergency cable there (like in some other cars), so that's it. I also carry the NOCO lithium jumper in the trunk myself (fits perfectly inside the right nook with the net).

Hi, I just installed sec downpipes and sent my TCU out to be tuned, and even though my car is in my warehouse I still wanted the trunk closed. I am 6’2” 200lbs and am going to have to crawl in there now with the front seats pretty much pushed all the way back. So my question is, can you help me out with the general location of the emergency latch please? I would like to crawl in there and get to the latch as fast as possible because I’m pretty sure it’s one way in, one way out for me. Thank you.
