Hi all I have a problem I had to take my battery back to halfords now I can not get into the boot to fit the new one I don't have the master key for this car only the valet key is there anyway apart from buying a new key to get into the boot I'm pulling my hair out

 

Can you open the drivers door? If so open the bonnet and find the positive post on either side at the fuse boxes. Apply power to one of the posts with a jumper and use the other cable to ground. Then you can open the boot with the switch on the dash.

If you can't open the doors, do a search and you will find instructions on using a hole by the license plate.

 

Thank you I can open all the doors so I will give that a go I will be ordering a new key next month

 

Thanks. Nice to know little tie bits like this.

 

It's fairly easy to get a key, you have a "tibbe" key. See this on how to decode your key: How to read a Tibbe key - XJ40

From there, you can order one off ebay based on the code you can read off the valet key. I believe the difference between the valet key and the master key is the tip, see this photo: https://www.jaguarforums.com/forum/x...wo-keys-99769/ Each has the 8 cuts, but the green headed valet key has a different tip configuration.

North American cars did not have a chip in the key, not sure about UK market cars. I think they do have a chip that needs to be programmed to be used as an ignition key. Should work the doors unprogrammed though.

 

That should be in the forum FAQ if it isn't already
