Battery dead, trunk won't open (even manually)

[Garrett]

Greetings all!  

 

Last night I pressed ignition button, starter clicked once, interior lights came on but engine wouldn't start.  I turned it off, made sure that there weren't any lights left on, tried again 2 more times without success, and finally had my wife take me to work at the hospital.  

 

This morning I tried the ignition button again, and NOTHING happened.  I tried my wife's set of keys also without success.  I tried to access the battery in the trunk to jump-start it with my wife's car but the trunk won't open with the fob button, the trunk button or the manual key.  We can't access the trunk from the interior of the car as far as I know.  Even the glovebox is locked shut so I can't access the user manual.  

 

Very frustrated, and humbly asking for help.  Has anyone else had this problem or know where I could turn for a solution?

 

All the best,

Hi Garrett

 

Here is a link for the XF manual....unlocking the boot/trunk is on page 29

 

Good luck   Trevor

Thanks Trevor!  Page 29 confirmed for me that I was attempting to open it correctly, but the key will not turn... Any other thoughts?

If its anything like the Mercedes boot lock then it will need an Oil spraying into it to free up the barrel.

The problem being that no one uses the boot lock as it can be opened through the remote and therefore tends to seize up.

Excellent -sprayed some Oil inside, let sit a couple hours, tried it again and (with a little bouncing/pounding on the lid) it opened!  Many thanks!

This thread is dead but it came up on google when i typed in a similar problem. My issue wasn't the trunk not opening manually it was a completely dead battery on a locked vehicle with no key to get in. I lost the factory key and transponder awhile ago. I ordered 2 remotes on eBay and had both reprogrammed to my vehicle. YES IT CAN BE DONE Dealers and most locksmiths will tell you it cannot. I am proof it can be done with the right Locksmith and computer know how. The transponders came with a blank key. The dealership wanted 250$ for a new key and i knew i could get into the car if i really needed to. So the adventure starts. 

TO get in the vehicle i used an air pump wedge on the top of the driver door. After a few pumps the opening was enough to get my coat hanger in and unlock the vehicle. Awesome in the vehicle now i can get to the trunk and replace the battery. @#($* no manual release for the trunk in the cabin of the car, and no key to manually unlock the trunk. You may find yourself in this position. There is hope.  Now its time to have a friend with their car TURNED OFF to help you.Jump the car as one would normally do but instead of a battery  apply the positive to this bolt located on the passenger side foot panel.

To reach this bolt take off the panel by first removing the "Jaguar" entry logo on the bottom of the door (brain !Removed! forgot what its called) then you will pop out the panel to expose the fuse box itself. The bolt pictured below is hiding behind a plastic cover, Pull it back and put on the positive cable. I cut the connection much longer so i could connect the negative in the engine bay. make sure you don't put the negative on a metal bolt that has plastic under it. Use as much steel frame as you can. Once all this is connected your car should have power Remember there is no need to have the other car on feeding it more voltage as the good battery can transfer enough energy with the car off. Now Get to the trunk, press the button and you're in. Disconnect immediately. Remember negative posts are to be put on last and taken off last.  

I did attempt to trickle electricity from a mobile charger to the fuse box but it kept clicking (which is normal on a completely dead vehicle) and couldn't get enough energy to pop the trunk. I also tried plugging in a positive lead to the fuse box itself with no reaction so the preferred method is the one above. I researched like hell for a couple days (i have another car and the time so why not) and couldn't find someone in my same exact predicament. Im sure it is bound to happen. I do need to do the window operation reset which is easy to find online, just google "reprogram windows Jaguar xf". I hope this helps some people out.

Did not work for me. Any other suggestions? Where exactly did you hook up your negative clamp for the cables?
