I have a 2000 Jaguar S Type 3.0, 103K; Over the past 2 months, the key would occasionally get stuck in the ignition cylinder, once for 3 days. My mechanic suggested that I spray a little WD-40 in it. I sprayed it with the key in the cylinder and it worked for several days. This morning it got stuck again. After 30 minutes of playing with it, I was able to get the key out, I stuck the WD-40 tube in the cylinder and sprayed it and the tube wouldn't come out. I had to use vice-grip to pull it out. It appears that a 'shaving' from the outside of the tube remained in the cylinder (although I'm not sure because the tube appeared to be compressed. After poking around inside the cylinder with a large safety pin for 2 hours, I was unable to find any plastic shavings. But the key will not go all the way into the cylinder and I'm unable to start the car. I tried lightly tapping the key with a hammer to force it in, to no avail.
Can the cylinder be repaired? How do I remove the cylinder without being able to turn the key? Can I change the cylinder without changing the PCM?
I just spent 3K on motor, suspension, and bodywork so I want to keep the car.
Any advice would be appreciated.

Perhaps a blast of compressed air will shift any debris in the lock?

My need taking apart.

WD40 is NOT suitable as it attracts dust. Use graphite as a locksmith should.

 

Thanks, I just tried the compressed air but it didn't help. I believe I need to replace the cylinder. I can buy a 'cylinder with key' from a 2000 S Type, from a salvage yard in my area. If I install that, will it work?

 

Thanks, I found that out after I did it. I believe I need to replace the cylinder. I can buy a 'cylinder with key' from a 2000 S Type, from a salvage yard in my area. If I install that, will it work, or do I need to do some type of reprogramming?

 

destroy the chip in the donor key and have them on the same keychain

or you can scavenge the chip off your old one and move it to a new 4d60 blank and get it cut, drilling may be required. @Sone might be able to help you out

 

Great Idea! Thanks

 

hi
the ignition lock comes out
you can remove it by removing the dash end panel, just sqeeze the two plastic tabs and its removed from hehind the dash, unplug and it out
the barrel can be removed from the switch as well
if you wedge the flap open and tap it on a bench it may come out, have you also tried a vacuum cleaner to suck it out
cheers

Thanks for the suggestion. I already ordered a used ignition switch w/key. I'm going to try Xalty's suggestion and take the chip out of used key and replace it with mine.

 

Today I swapped the $95 salvage yard ignition cylinder, key, and barrel. I also transferred the chip from my valet key. It took me a little over an hour. The car started right up. The only downside is that I now need to use two keys. Thanks to all, especially Xalty, for their assistance.

 

Now that you've got the car running again, can you disassemble the failed parts? Maybe you can figure out why the old cylinder was acting up and fix it. Sounds like some debris was jammed in there. With any luck, you can fish it out from the comfort of your workbench and get the operation back to normal. If so, you could reinstall the original part and go back to one key.

 

Yes, I will look into that.
