I have just joined AML and need help big time. I have a 2001 DB7 with a fully dead battery. The key goes into the trunk lock, turns, but the mechanism does not open the lid. The remote trunk light goes on but the trunk does not open as the battery is dead. I have tried to charge the battery through then cigarette lighter with a battery tender trickle charger but it appears that no charging is getting to the battery (charger has been attached for 2 days). I have taken the right rear seat out but can see no access to the trunk space from this area as there is a solid metal wall there. The top is up at the moment. Can anybody come up with some ideas? The car is locked in park. The ignition key turns but obviously, no power when pushing the red start button. I need either trunk access or a way to charge my battery. All suggestions are welcome. Thanks, Larry (ungy)

I'm not familiar enough with the car to know exactly where the manual release is, but I have a couple of thoughts. There's always a manual release...either a handle in the cabin, a hidden handle by the rear seat or inside the fuel filler door, or with the key in the trunk lock.

The key lock in the trunk is generally designed so a slight turn activates the electronic release, and a further turn (which has a good amount of tension) mechanically releases the latch. Most likely you just need to turn the key further in the same direction that normally opens the trunk to activate the mechanical release...it'll be stiff.

Chargers in the lighter sockets wont work unless the ignition is on.

Boot release within the centre armrest box will only work when the battery has power.

No other manual releases, except on US models which it inside the trunk ;-)

As posted above you should still be able to manually open the trunk with your key.. try turning it a little further with more tension but please ensure not to use too much.

There are points to attach power to the battery if all else fails, these can be found under the car, within the engine compartment and in the passenger foot well.

Thank you...Power points?

My car has been parked in the garage in Florida and I will be going there to start it up in 4 weeks. I think I have to get some juice to the battery so it will have enough power to activate my trunk remote.

Do you happen to know where the "power points" might be located either under the hood or elsewhere so I can attach a charger to them and charge the battery?

Your response is much appreciated.

PS..I have tried turning the key in the trunk many times and even with a lot of torque but it appears to be broken and I expect to replace the trunk lock when I eventually get it open.

Thank yoiu again....

Power Points

As the battery is mounted in the trunk, there are a few points where battery power needs to get to.

1) Under the hood (bonnet) on the bulkhead towards the rear of the engine, you should find a stud where the battery feed connects before running off to the starter motor etc.. If you can safely do so you can connect a charger to here ( + Positive +)

2) Within the Passenger foot well you should find TWO fuse boxes, at the corner of each of these you will note a thick cable, this is the battery feed that connects power to the fuses. Connect a charger to any of these points or you could pull a fuse and connect the charger feed into the supply side of the fuse holder ;-)

3) Under the car you could access the starter feed, though this is tricky due to the exhaust and cats.

I have circuit diagrams for a 2002/2003 model, however these are VERY similar to the 2001 model, so if you need help locating a fuse for connecting a 12V charge feed, let me know.

Thank You Squid

Squid,,,,you have been a big help. I will try your suggestions. I assume I will need to attach the Neg. clamp of the charger to a part of the vehicle to get a ground???

Also, is it possib;e to ppurchase a new trunk lock/mechanism and have it keyed to my existing key set?

Thank you again.

Just clip the ground to anywhere on the engine, exhaust etc..

As for lock mechs, I am unsure, never had to mess with one before.

I very rarely use my key to open the boot. So if battery charge is a problem for you (not using car for a month will flatten the battery) then think about using a solar charger to keep it topped up, though it would need to produce a good 3A @ 12 - 13V in order to keep it from going flat.

You can of course use the battery disconnect switch to reduce consumption but beware the windows will not lower until you re-learn them, plus parts of the security system will be in-op.

If it's in a secure place with power then plug the battery charger in and leave the boot open a little, but remember to remove the two bulbs as these draw a few watts and get warm.

Given that owner numbers are low for this car, it's nice to see some activity in this forum at last. As I'm a new owner, I'm finding Squid's knowledge very helpful. So Squid, how have you come to be so informed on the DB 7s? Is it your profession or are you a car nut like a lot of us?

I own a DB7, therefore I need to know about things :)

Every car that I have owned I have made it my goal to learn as much as possible.

I do all my own servicing so get to know the car very well during the course of ownership.

I have many books on the DB7's and all the tech info for the 02 / 03 models.

My GT is not a garage queen, it get's used all the time and I also drive it the way a V12 should be driven ;-)

I can confirm it easily get's to 135mph in 4th and will do so from a standing start in just that one gear !!

Sorry if this suggestion is silly, but have you turned the key clockwise or anticlockwise? My DB7 I6 (1996) requires the key to be turned anticlockwise to open the boot. I always find this the unnatural way to twist the key. It took me a few attempts to figure it out.

Also check the battery in the security fob. I have had many strange issues with doors partially unlocking, transmission fault lights and car not starting due to the security remote battery being alive enough to confuse the car security and the operator ...

Good luck
