THE INTERNATIONAL JAGUAR 'S'-TYPE REGISTER FORUM

Right Cass,
What is interesting is that the FS number range is limited and how so many 'S'-types had the same keys!
Check out Newsletter Vol. 6, No. 9. to see the cars built the same day as P1B79909DN and used the same keys

In my box of many things I found a spare boot locking mechanism over the weekend and decided to pull it apart to find out how it worked.
I did not have a key for this one so could not see how it worked without taking the lock out. There is a small locating pin at the base of the lock under the operating handle which you need to drive out. This releases the lock which can be pulled from the barrel.

The lock is unique to the boot in that at the base of the lock there is a section that allows the lock, when turned to the open position, to push the internal mechanism forward so it engages. When turned to the lock position the lock is disengaged as the mechanism springs back towards you.

If you have lost your key and the boot is locked you should be able to get a pin driver into the side of the lock to drive out the small locating pin. I used a centre punch to start it then a 3mm drill bit tapping it with a small hammer. Once the location pin has been driven through and the 3mm drill bit removed the lock can be removed from the barrel. You will now find that by pushing a screw driver in to the hole to push the mechanism forward the boot can then be opened.
Having removed the lock on the side there is a number somewhere in the region of 800 to 999. This is called an FS number and by going to this company https://www.replacementkeys.co.uk/unionfs-series-keys-to-code.html?gclid=CjwKCAjwrcH3BRApEiwAxjdPTclJWhV1AwgM-7-TC0DAL-6kgwgmxWrGvpxazSFDRptQ0Ow6x79xMxoCsF0QAvD_BwE you can put in your FS number and have a replacement key cut. They will also cut spare keys for the ignition and doors.

I think I am right in saying that a new Jaguar came with two keys both FS keys with different numbers. One key fitted the driver’s door and the ignition whilst the second key fitted the glove box and the boot.

Thanks. I have some keys on the way from the UK supplier. Ordered a couple of new ignition keys also. Cheap too.

In the UK most locksmiths have blanks that can be cut using the original but failing that SNG Barretts supply the FS key blanks here. https://www.sngbarratt.com/English/#/UK/parts/c5fe5d84-2701-424a-ab7d-73236b56ad6c?fromList=Search%20for%20%60FS%20keys%60
The key and the lock should also have an FS number on them and if you go to this web site you can have a blank key cut to the FS number and then sent to you cheaper than buying the blank from SNG. https://www.replacementkeys.co.uk/unionfs-series-keys-to-code.html?gclid=Cj0KCQjwuJz3BRDTARIsAMg-HxX9jCC5nnM3Ag3W0RMnBOFEcP1og-zf9IZK51r-Hq26hCvONWZnUHcaAtsfEALw_wcB

My new (to me) lock has arrived. It has only one key. Does anybody know how hard, or easy, it is to get a copy made?

Easily done Nigel. Put the keys in your jacket pocket on a hot day then throw it in the boot and walk off to buy an ice cream. Obviously this is just an example of what could happen but not to me......

I was at a car show some years ago with my wife and somehow she managed to lock the S Type's car keys inside the boot, I had to go round all the autojumble stalls and borrow keys from them to find one that opened it.

I am much relieved, but also a little puzzled. Operating the release handle with the boot open does not cause any motion in the mechanism that locks onto the pins. I can see the horizontal levers moving a little. I guess it has to be engaged (ie boot closed) for anything to happen there. Always learning.

Much relief and well done for figuring it out. Better than having to cut a hole in the boot somewhere.
Good result but everyone should still be aware of getting anything trapped in the boot locking clasps and pins.

The boot is open. It was pretty simple - a bit like how I feel now for not figuring it out earlier. :oops: Rob's picture of the lock was the big clue. I realized that what I was seeing on my car was not the lock cylinder but the mechanism behind that it engages with. A bit of brute force applied with a screwdriver turned that part and it popped open. Much relief. :D Thanks folks.
