Just to follow up in case anyone else needs this information, I received the replacement key blanks for the ignition and the door/trunk locks. The ignition key comes from Waso and has the black plastic "handle" just like my original. The other key even has the embossed "Leaper" logo stamped into it. They both fit perfectly. For $25 I think I did quite well. I plan to keep the spare door key in a hidden magnetic weatherproof case so that I can actually enter the car, and to keep the spare ignition key in the glove box so I can drive home. Anyone have any thoughts on where to hide the key case? See link below.

Those magnetic key hiders are Notorious for falling off without the owner noticing, and almost No One checks if they're gone walk-about until they're NEEDED!

I put mine in the trunk, stashed in a tool kit I keep back there, which I can't lock the trunk unless I have the keys in my hand. Almost no one knows anymore (except Jag drivers of course) that these Elderly Jag trunks don't lock automatically like every other car on the road does, so I feel quite confident my extra key is secure.

WOW! Lnr. Now why did I not think of that - Brilliant! Ian

 

The trunk on my car locks automatically when I lock the doors.
