I'm not liying I wish I was, but I unhooked the battery to do a head and cam swap and forgot about the key fob and key in the cup holder. I closed everything and have the battery disconnected. Car did not come with a second key/fob. Is there anyway to power the car with the positive disconnected on the battery and no access to it? I heard you can do it through the starter but my battery is disconnected will it still work?

Trying to evade from paying the dealer 70$ to make a key thanks

And no I'm not lying I seriously did this, any info helps. Trying to get back on this project.
Thanks in advance

Help me figure this.... If the car had 12 volts of power, what would that do for you? The only fob/key you have is locked in the car?

Or are you thinking of trying to coat hanger it open?

I would call a locksmith. They could probably make a key for the trunk and get you in that way. If you have AAA call them and see what they say. You know there is a pull cord for the doors in the drivers side of the trunk? One for the gas flap and one for the door. Can't think of a way to connect the battery unless you can get under the car and reach up to the + and wire and then jump it and to a ground on the car. Not sure what it would do to the system but probably wouldn't hurt.

Next time leave a window down so you can pull the door opener on the floor. That's what I do if working with the battery disconnected. GL

Ik but the car is outside and it was going to rain tonight.

Can't coat hanger it, I have a battery charger wondering if I can put that to the starter.

I thought I read on this forum that someone took out a tail light and applied 12V to the tail light wire harness?

It's late and I might be wrong...

If you do get it powered up, then what? Keys and fob still locked in car..

No it's true I'm wondering if it will work with the positive cable in hooked on the battery

NOWUCME

The starter I would think has a switch from a computer or the ignition so I don't think that would not work since the switch to positive would still be open? Anything with a switch between it and the battery would probably not work. But like the other poster said you still need a key or the fob/but if you leave the fob in the car it normally won't lock the doors. whether it will reverse that if you get power I don't know.

Check what I said about getting under the car to the positive lead to the battery. Probably can't reach it and have to be careful jumping to it not to touch any ground....edit to my original post

get a 2nd key, unlock it the right way (Through the trunk key hole).

Maybe a locksmith can pick that lock? or, if you can see your key in the cupholder just fish it out with a coat hanger. The windows should be slightly open because of that auto-down auto-up thing.

NOWUCME

I would doubt you could get anyone out tonight unless it was through AAA and maybe not there. sleep on it

And I thought I was having a bad day. I cannot think of a way to get the hood open from outside. Spring for the $70 at the dealer, the locksmith will probably be more. It will be better than taking the chance on damaging the car plus you will have it in the future.

Remove the left tail light and drill a hole big enough to slip a coat hanger in (looking through the rear window) and pull the door cable.

battery charger to starter and ground will power up the car

This.

Or as others have suggested, go to the dealer with the VIN and have them make you a key for the trunk.

Exact same thing happened to me... when I was in Canada.

With the positive unplugged on the battery

Your gonna need to have a key made. Battery charger will power up the car but that won't do any good. Fob is inside the car and will not unlock the car.

Yes, been said many times and is total . The tail lights are all powered by the BCM computer and not directly from the battery. Backfeeding power into the BCM computer like putting power into your computer through a USB port instead of the A/C plug is a very bad idea.
Partially correct. The starter solenoid is the switch and the big cable to the starter solenoid is tied to the positive connector for the battery and so the rest of the car.

I wouldn't do that with a charger and a maintainer might not turn on without some positive feedback. I would look for another battery and jump it to the solenoid before trusting the voltage from a charger isn't too high without a battery and would fry the computers..

And to answer the unanswered question above about what does powering the car gain you if the FOB is inside, I assume the doors are unlocked and you just need power to the door solenoid to open it. If they are locked putting power to the car is not going to get you anything.

Finally, the floor levers would also open the door if you have a wire long enough to reach one.

FortMorganAl

Oops. Reread the first post about needing a key and the OP is SOL as expected from prior posts. Reaching the lever on the floor is the least expensive solution. Next would be a locksmith. Next would be a dealer. Next would be breaking a window. Next would be towing the car to a dealer.

not sure what year you have, but with my 07 it is a regular old GM key, dealer charged me under $10 for a new key and to cut it, only issue I had was dealer didn't have the key in stock so had to wait a day, luckily I have 2 fobs and now 2 keys
