I have a 2003 x type I cannot get into the car the battery is dead

Do you own a professional type scan tool ? Would need to see if the instrument cluster can communicate with scan tool . That would be a priority . If the instrument cluster ,for some reason wouldn't be talking,checking power an ground for the cluster . Batteries going dead , changing batteries without a alternative power supply can cause modules to go to sleep permanently ! Battery Disconnect or Replacement Problems I'am not saying that's what happen to your's . 2003 to 2006 GM had cluster problems ! The solder use in the cluster caused silver migration , instrument cluster caused a drain on the battery overnight . Watch these videos !

Chevrolet Truck Battery Dies Overnight Part II

Chevrolet Truck Battery Dies Overnight Part

plug a cheap jumper battery cable into the cigarette lighter. They are the kind that has a cigar lighter plug at each end. Or, hook a 9 volt battery to a cigar lighter plug. That should be enough to operate the trunk switch.

If you can get the hood open, then look for the alternator and use the heavy gauge single wire. Put the (+) of the charger on it and the (-) on a good ground.

Have Battery tested for a bad cell

You will need a jump box or an external 12 volt power source.

Attach the negative to the frame ground.

Attach the positive to the starter MAIN (larger) cable.


Pop the trunk

Remove the jumper box connection and start charing the battery.


Please rate my answer if it's useful to you.

use your ignition key to open the trunk, the key hole is hidden just under the opening button and to the right side

You must charge the battery or you can use jumper cables from another battery to your battery to activate the electric trunk release, just be sure you hook up the jumper cables correctly ( cable to + on the battery and black to _ terminal of battery)and wear safety glasses when hooking up cables this should release the trunk. Also as a precaution always hook up + or red jumper cables wires first to prevent a arcing spark which is not terribly dangerous but this order in which to connect jumper cables is recommended.

A common problem with this is a dead battery this will put it in lockdown-dealer area.

The long story short it probably your battery being dead or a computer glitch (if there is nothing else apparently wrong with the car)
One is the battery life of an older model jaguar is going to be short compared to newer models. I noticed I have problems with my battery going dead around the 6 th year of the cars life since then a bunch of silly issues. One thing to know is if your car doesn't start it (even if your lights work) is that your battery is to low for the ignition to work (which requires high voltage). You can try removing the batter than re attaching it back to the car.
I have these issues typically when i don't drive for long periods of time in the winter (mostly). The car contains a big gigantic computer (which a lot of owners do nt realize) controlling everything weather you can start the car or not (it has a security system still armed) so when the computer is not working properly or the battery is too low (and their are no other apparent reasons). I would suggest trying a few suggestions on the jaguar forum because its very specific but you would be surprised how stupid the issues end up being. Flat bed a jagaur to any dealership and your already in the hole for 150 plus.
good luck

There is no security features 2 b overridden. U have 2 change the battery fluid(acid) and charge the battery. That is a possible solution 4 ur problem.
