I accidentally left my radar turn on in the car. For two weeks

Battery is complete dead. I put the key in to see what would happen and now it won't give the key back.

I threw it on the Porsche battery maintainer about 5 hours ago and no progress. Not even a hint of the dome light.

It has a brand new battery in it so I'm not quite sure it isn't bouncing back.

Anyway, is this salvageable and how do I get my damn key out???

 

You might need to boost it. Once it has power it will release the key.

 

The trickle charger can take "many" houirs before she comes to life.

Relax and I suspect that all will be fine by tomorrow

do NOT pull on the key until you have pull,
without power the key wont release. you will destry it. i did.

 

See the Operator's Manual - you can go into the fuse panel and and pull out a stud that you can put a positive jumper cable on it; you'll need to find a point on the car where you can connect the negative lead (door closer, suspension, frame). That will allow you to remove the key immediately.

If your battery goes dead and you cannot open the hood to gain access to the battery, this approach through the fuse panel will let you open the hood as well. It's important to understand how all this works before you have a problem, most garages may not know how it works. I didn't but fortunately I was able to reach my local service organization when I needed them.

The battery maintainer should work after 24 to 36 hours.

 

I'll go ahead and let it sit then. No rush. Don't need the care. Sucks that I can't fully shut the doors as the widows won't dip because of the lack of power. I just shut them to the first click. Hopefully she'll be back up tomorrow morning. Thanks for all the advice.

 

In the mean time, the FL lizards who are currenlty mating inside your car would like a round of drinks please.

 

that works i paid 100 bucks for that once ...

 

So far it's been on the porsche maintainer for over 24 hours. Nothing. I heard a mild clicking in the area of the ignition switch.

Weird as this is a brand new battery (2 mos old). Would have thought it would have bounced back quicker after a complete discharge.

So if I don't have any juice by tomorrow, should I assume the battery is toast and replace it?

Also, recommendations on battery replacements? And no Luis, I'm not putting in one of those retarded little braille batteries. I managed to drain a giant interstate battery so I'm certain I would kill one of those race batteries in no time.

Whatever you recommend also needs to be able to fit with the OEM battery bracket.

Thanks.

 

Relax...... your patience will pay off

PM me if need be

You can get this solved in a matter of minutes by following the owner's manual instructions as mentioned above.
Pull the fuse cover (driver left foot kick panel)
Extend the red jumper terminal
Connect positive of any 12V source (this is not to jump the engine, just the key release and the front trunk latch.)
Connect the negative to the door striker (bare metal hoop that holds the door closed.)
This should immediately release the ignition key -- turn full range clockwise and counter-clockwise to release.
Leave the external power supply connected.
Use the hood release button on the remote to release the front trunk. For some reason, this works with less power than the normal trunk release on the door sill.
Now just or recharge as per usual.

You battery charger/tender is probably not getting a circuit from the accessory cigarette lighter to the battery, so waiting for it is probably futile.

If the key still won't release from the ignition (this has happened to me when the battery created an open circuit and enough draw to prevent the small jumper from supply enough current) then remove the wire pin from the back of the fuse panel cover, remove the small plastic "chock" from the ignition plastic surround and insert the pin to manually release the key.)

Or call your dealer and they'll have Porsche Roadside come or they'll talk you through it.

By the way, if you had a tiny Lithium battery, it would have a discharge prevention circuit that removes the battery from the circuit if it's being drained beyond usable voltage levels (and it can be reset to allow the car to start with no fuss.) Auto parts stores sell a small device that connects over the positive terminal of conventional batteries to provide the same function.

 

I had the exact same problem on my 08 gt2. I could not get the trickle charger (porsche battery maintainer) to charge up the system to release the key. I tried for 48 hours. I went to the owners manual and had to charge the system through the fuse box in order to release the key and finally open the hood to access the battery. Then I put a battery charger on the battery and the next day it was fine. Now I keep the car on the porsche battery maintainer all of the time and have not had a problem since.

 

I wouldn't consider a battery maintainer to be a battery charger even though it charges. The rate is so slow that you would probably have to leave it on for weeks. A regular trickle charger (2-3 amps) would take several days if not longer to charge a car battery. You would need a higher amperage source to re-charge your battery.

 

just for reference, my gt3 with a 4 month old odyssey pc680 can sit for 2 weeks straight and still turns the crank. and i never turn the V1 radar detector off and my traqmate always plugged in to cig lighter.

the difference is that i always turn my alarm on which basically automatically shuts many things off.

 

The car is junk. Please PM me and I will come remove it from your garage and discard imediately.
