How can i open the trunk to my 1999 volvo s80 when its not opening with the key pay, or the button and i dont have a master key? I can get into the trunk from the back seat but i cant figure out how to pop it manually.

ulock door twice trunk will open

open your trunk, between the rear speakers.

its were you stick the key in trunk,if u look under there its a black spot there u have to pressed it then it will pop open..

Actually if you look right above your license plate there is a plastic cover covering a key hole on your trunk. Look right up buy license plate lights remove the plastic cover and you can manually use a key to open the trunk.

It's a black cover right next to the switch you press to open the trunk. I have an S80 trust me it's there nobody knows about it.

have a power supply connected to the acc, in the vehicle,

it a bad trunk lock or handle switch

THE key code is what you need or a dealer should be able to give you a MASTER-KEY with the vin# and key code is on a little black tab in the owners manul package i hope this helps

if the back seat folds down you should be able to get in that way and pull the release lever and the trunk will pop open
if the seat does not fold down you may need to get a locksmith

Why don't you charge the battery under the hood so you can pop your trunk. You can't do anything with a dead battery.
