Hi there,

Well It's very difficult to gain access  to xj8. Short of having a key, No. But a Jaguar Dealer can get you a new key for your car typically in 3 working days max. and possibly overnight. The new key will not start the car until it is programed but it will open the trunk. You might look in the glove box for a trunk release button. The computer systems are very complex on a Jaguar which prevent theft. If you are desperate to get in you could also try going into the trunk though the back seats.
Instructions for removing the rear seat..
1. Remove the rear seat cushion.
2. Detach the rear seat cushion front retaining clips. 
3. Slide the rear seat cushion out of the retaining hooks. 
4. Remove the rear seat cushion. NOTE: Remove and discard old retaining clips.

1. To install, reverse the removal procedure and make sure the safety belt buckles are located through the cushion. note. You have to Install new seat cushion front retaining clips..... Post comments for further help or information......

Good Luck!!

There should be two wires, one going to, and one coming from the switch. You can pick either one, and it won't matter. If the first doesn't work, press the button, and they become the same(the switch just connects the two). the other wire will go to either a hot wire or a ground(body or frame of the car), depending on which the native polarity of the wire is. If one doesn't work, switch the leads, and the other will. Other option, is to remove the back seat, or if you have a folding seat, drop it and go in that way.

I was changing a fuel pump in my 01 xj8 and had to disconnect eletric wires now thati closed trunk cant get it open have electricity but must of disconnected wire for trunk lock now the key wont open it...

If the key won;'t work, your only other solution is to remove the rear seats. You may be able to reach through the rear seat bulkhead and pull the release catch.

What options do I have in gaining access to the trunk of my 2004 jaguar xj8 that has gone into valet lockout

all back seats are either screwed down or hooked in. you need to use a little muscle and lift up your back seat to see which is which. there is no other way to gain entry to your trunk.Trust me Ive locked my keys in my trunk too. Now i have a hidden spare to my door and trunk. GOOD LUCK

How do I access trunk entry into my 2004 Jaguar xj8 when now it has gone into valet lockout?

I believe that this is to protect valuables left in the boot when parking the vehicle. I read here that there is access some where in/ near the glove box but I cannot remember exactly what it was . Surf the net under Jaguar valet problems and you may get the answer.

2006 Jaguar XJ8. Battery dead. Cannot access trunk with push button, button on dash or key. Is there an alternative method of jump-starting the vehicle?

Owner's manual should show method of using key to open trunk in this situation. On some, you turn key as far as it will go, then manually operate latch and key will turn further and unlock trunk. No manual latch? Should be a way under hood to supply power from jumper cables.

My trunk will not open when I push the badge button!

if i'm not mistaken... i believe there is a disable switch located around the lock mechanism when you have the boot open... it might have accidentally gotten bumped

I have a 1998 Jaguare xj8, the battery is dead and the trunk will not open as a result. The key will not open the trunk nor will the release inside open the trunk because of the battery being so dead. Any...

If the locking mechanism fails or no power is available, it is possible to open the boot using a long thin screwdriver through the lower right licence plate mounting hole.

Follow the linkage rod from the lock mechanism itself going left, towards the centre, to where it joins the catch mechanism and push here. It can help to shine a light through the left side licence plate hole, and also to get a second screwdriver in here to take a little of the tension off the catch itself, though not too much or it will spring back into place.

Cant get my 99 xj8 out of valet mode, and my trunk will not open.

There are Valet keys (often with a green knob) that will
only unlock the front doors and the ignition but not the
glove box nor boot/trunk.

When either the front door locks or the console button is
pressed, all the doors should lock. Likewise, when either
front door is unlocked, all the doors fuel filler lid and if
selected, the boot will also unlock.

Boot lock has three positions. Unlocked to the left,
automatic with the doors in the center, always locked to the
right. Simply remove the key in what ever position you desire.

The locks can get confused and not work correctly. Simply
sit in the car and manually lock all the doors. That will
usually get the locking module sane again.

I can nit open my trunk on my 1996 jAGUAR XJ6.

ok, if the key won't open this then the lock is jammed and if you don't want to damage anything, I know I wouldn't, I would take it to a mechanic. The jammed may have been what killed your battery if the valet trunk open was not working it may have been shorted out. There is a way to jump vehicles with the battery in the trunk like that but I am not familiar with it and if the buttin doesn't work to release the trunk it would do you no good anyway. most likely you are looking at replacing teh truck locking mechanism.

Have 1996 xj6 valet was pushed master key dont work in trunk how do i open trunk?

Had similar problem when keys accidently locked in trunk.Solved by drilling 1 inch circular cutout (series of small drill holes) behind number plate above lock. Lock operating bar then visible. Lock released using long nosed plyers. Note.. release button on lid failed to operate as by coincidence wiring loom failed where it passes trunk hinge ! Hole re-sealed and number plate replaced. I had vallet key but this dosnt open trunk. Hope this helps Pete
