The electrical part of my ignition switch is good, but I have to replace the ignition key cylinder in my 1990 XJ.
The question I have is there there a span of years that the cylinders interchange in this car, for example like a cylinder from 90 to 94 will fit, or do I specifically have to buy a ignition cylinder for a 1990? Thanks.

 

Hi Phydeaux1,

The Jaguar Classic Parts website (jaguarclassicparts.com) is a good place to compare parts diagrams for different model years. It appears that the "Steering Column Lock" barrel is the same for at least the models from VIN 594576 through the '92 models:

For VIN 594576 - 667828

Steering Column Lock - Parts For XJ6 (2.9, 3.2, 3.6, 4.0) from (V)500001 to (V)667828 | Jaguar Heritage Parts UK


The part number is JLM1983, but the circular arrow symbol means the part number has been superseded.

Searching that part number at jaguarmerriamparts.com (the Jaguar dealer in Merriam, Kansas who sells Jaguar parts online at discount prices), I find that JLM1983 has been superseded to part number JLM2145, and that same lock cylinder fits all Jaguar XJs and XKs from 1988 to 2006 !!! It's still available for $112.13. I assume you will have to supply your VIN so the cylinder can be keyed for your car.

What problem is prompting you to replace the cylinder?

Cheers,

Don

 

Thank You Don for your reply. I had a new key cut a while back, it opened the door, it opened the trunk, it fit in the ignition and started the car but would not come back out, tried a lot of times with lube etc. Its been stuck in there for quite a while, figured I would have to buy a new cyl and key to fix it which prompted me to ask what years works in a 90 before I went shopping. I finally got around to removing the cyl today with the key stuck in it. I got very lucky and managed to get the key out of the cyl on the bench. I wire wheeled the key and got rid of all the sharp edges, it goes in and out fine now, reinstalled the cyl and all seems well. But thank you for the reply, that's good info to hang onto regardless.
