Have an Aston Martin vanquish 2007. Battery is dead and can't use remote to open the car. The key does nt work either (both sets).

I used to do Wedding Fairs at the Swan Revived Hotel in Newport Pagnell just down the road from Aston Martin. They used to line up the Director's cars at the front under an AM Flag!

Aston Martin Vanquish Flat Battery
There's a relatively easy answer. This video may help https://www.youtube.com/watch?v=zz6rnG9VznM

does it crank over

IIRC it is in the trunk/boot. However, there is a BATTERY + post in the engine bay so you don't need to pull the trunk/boot carpet up to charge the battery.

Location should be available from your Hand Book.

It is usually under a black plastic cover marked + in a circle. You attach the Positive+ clamp here and the Negative - clamp to a convenient metal engine component...such as a bracket.

WARNING: Modern vehicles are full of electronics. When charging a battery you must either remove the battery from the vehicle or use a low Amp charger set to 2 to 10 Amp for about 6 to 8 hours.

Failure to follow this proceedure will often result in electronic component failure of the 6 to 10 computers (ECU's.) placed around the car. Any of which can cost $1000.00 and up to replace.

I have just re ECU'd a Mercedes for $5,400.00 for a similar mishap !

Many European vehicles are equipped with a ballistic battery disconnect feature ....that disconnects the battery + cable in the event of a wreck. It is a fat bright RED component and must be handled with care.

You will also find some feature on the car will not work after charging the battery due to lost memory. ..such as window express down and radio pre-sets or activation code.

If you feel unable to reset these feature you need to go to the dealership. There are very few shop that are equiped to work on these machines.....and Aston is not forth coming with test information.

on the door handle is a plastic cover ,look carefully and behind this cover is a key hole could be passenger side or drivers side look for a little sort of slot /prisehole on both sides of vehicle and it will have one .

Below is the procedure for an Aston Martin Vantage, perhaps the vanquish is similar?

somebody else had this and their is a point behind something to put some power to it but i cannot remember where it was they did post back but at my age i dont remember a lot ,did i give you back that 20 euros i borrowed ??

Take it to a garage and ask them to test it. It should take a few seconds to test and cost you nothing if there a nice person!

you have to take off the underbody shield to get to it.
you will need a ramp/pit to be able to get to the many bolts/clips holding it on....best of luck....your looking at about 3 hours labour min...

it is battery poor
