How to open the trunk on 2004 Jaguar XJR. The battery is dead.

see if this link helps you out.. https://www.google.co.uk/webhp?sourceid=chrome-instant&rlz=1C1CHBD_en-GBGB719GB719&ion=1&espv=2&ie=UTF-8#q=How+to+open+trunk+with+dead+battery+on+1999+xjr

it was a common prob with those cd changers in the boot/trunk disconnect it and let the head unit connect to it if still no good and the wiring/connectors are good the cd unit is faulty

You have to reconfigure your fob via your valet button, this will enable the bootlock to recognise the singnal from dash button. I know your battery is dead, start it with a booster or jump leads, take for a good run and then when you think your battery has enough juice try to reconfigure. hope this helps, Jonjo.

Put 12 volts into cig lighter socket, with key on then try boot lock
the centre pin on plug is usually +

First, check your fuse panel and see if you have a blown fuse. Replacing it will resolve the issue.

If not, fold down back seat and pull the emergency cable located near the key hole.

what car do you have?? is it a newer one were the battery is in the boot..?? well its easy if thats the case alls uhave to do is open the hood and charge it that way either jump start or use a spare batery...(connect ground to positive!)

It takes a deal of time and patience to charge via the cigarette lighter socket though there should soon have been enough power to open the boot.

It should be possible to access the end of the main battery lead in the engine compartment in order to jump start the engine, provide power to open the boot or to charge the battery, if the battery is healthy enough to accept a charge. Some cars with a remote battery provide terminals for the purpose though I don't know whether the Jag does. If it doesn't the main battery cable terminates at the starter motor.

you should have trunk key all cars trunk can be open remote by the inside. if any fails you always have a trunk key. check your ignition key .i seen ignition keys do both. it cranks car and open doors and trunk.

I simply opened the bonnet. Connected the battery charge positive to the + feed on the back of the alternator, connected the negative to the body. Turned it on, immediately the interior light comes on. Turn on the ignition press the cabin boot switch and it opens the boot. Charge battery as normal. Easy Peezy

I f it is like the XJR, the cig lighter is electrically switched and will not work. Find the hot point and and ground in the passenger side heelboard. The ground is two wires together scewed to the body an the hot point was a bolt attacted to a large wire and covered with a black rubber boot.
