Trunk I recently bought a 1988 XJ6. The ignitino key does not fit the trubk. When I lock the doors all the doors lock but you can still manually open the trunk. Is there a separate key for the trunk or is there a problem with the lock?

Your car may have had a new ignition switch installed - hence the different key. The FOB may not be programmed properly to lock / unlock. Have you contacted a MB dealer?

You have listed the vehicle is a 1987 Jaguar XJ6. The trunk is not electronic and only unlocks with the key as well as both the gas doors. Any issues here then it is your key or the actual trunk latch. If you do have a 1988 model year then the trunk lock has 3 positions. locked all the time, unlocked all the time or the vertical position locks and unlocks with the vehicles drivers door lock. If the trunk button (paddle) is loose and moves but nothing happens then the inside rod has come loose and you will have to manually operate the latch by removing the license plate and taking a long screw driver through the lower plastic bungs. The fuel flap is a separate unite and does have a manual release but you need to open the trunk to get to it. If the fuel flap stays locked all the time then the actually filler neck module will need replacing.If you have a 1997 which has the electronic release button to open the trunk (95-2003) Then you will need to firstly lock all door and unlock the drivers door 2 times. Check the fuel flap is now released, if not then the fuel flap actuator located on the filler neck inside the trunk is bad. If the trunk does not open with the remote, inside car switch and trunk mounted switch then the passenger side trunk harness is broken. Open the trunk with the key and on the right(passenger) hinge there is a grey plastic cover, remove that cover and carefully peel back the wiring harness cover and you will find 1 or more broken wires. Once the wires are repaired then I recommend you zip tie them in place and retest the trunk release button.If this does not answer any of your questions please feel free to email [email protected]

use wd-40 or liquid wrench and a tooth pick- use toothpick to hold the little metal flap in lock back and spray oil inside- locks weren't uses much as you have remote locks- lack of use can cause rust/lockup
key will start engine? if not- you might have gotten the wrong keys- or there might be a different one for the door locks from the ignition key

The valet button is in the center console. You can also use the manual key (the black one) in the back key holder (located in the XJ6 label on the trunk), that will overide the electrical lock and you can open manually.

Good luck!

open all doors from driver side electric lock now try key

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

Is the key you are using green? If so, it is the Valet Key and it will only lock the door - it will not work on the glove box or the trunk.

spray around the gas door with wd40 a couple of times and wait a few minutes for it to disolve the salt or crud or corrosion. Sppray again and even a third time of necessary.

once the door is opened, spray it again, including the hinge and the catch. then spray it again in a week or so and you will be good to go.

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

cover under bonnet with a big P on it and negative is anything metal on the engine
