You need to pop the bonnet and get some jump leads and connect it up to the positive terminal under the plastic flap on the right hand side. Then attach the negitive lead to any metal part of the engine.
This will power up the car and you will be able to use the keyfob to open the boot to gain access to the battery.
It's in the boot, or trunk if your in the USA. If the battery is flat, then you need to open the boot with the ignition key - look between the X and the K on the rear badge.
When you have no battery in your 2001 Volvo s80 and the trunk will not open how do you open it when there is no electricity
take two back wheels off then undo exhaust then try boot it will defo work
Look under the boot lid and you will find a plastic blanking plate just to the right of centre. Flip this plate out and insert key in the lock that is now exposed. Simple eh!
manually: insert key, turn, lift boot. voila :)
You'll have to use the key.
Hi - Below the push button boot release is a key lock, under the lip between the number plate lights. Seems obvious but it is well hidden - I had to ring Lancaster Jaguar in Sidcup to ask where it was!
Unlock the door with your key.
Use your key to unlock the door.
Open the door with your key and pull the bonnet release.
You need a locksmith.
Recently i had the same problem when my 2006 bmw 320i's battery went dead and everythng seemed locked, even the key got stuck and i had to pull it out forcefully. To open the boot you have to charge the battery, now you must be thinking thay battery itself is located in the boot. Right ? Still you can charge the battery from the bonet(hood) of the car. you can open it coz it can be opened manually. now on the middle left side of the hood, you can see a metal plate with a red cover on it. Connect the positive wire of your other charged battery with it, and connect the negative terminal with any of the screws you can find near that postive wire on the hood. Now try to start the car and once it gets started, open the boot of your car and try to replace the battery because it may happen again.Hope it may solve your problem.Nouman
