John Jones at one time had a connection to get keys made from manufacturer.
But you HAD to have the little rubber tag to get a copy made.
I don't know if there is a connection with the manufacturer any more.
And to be honest I don't even remember the name of the company anymore. Those keys were pricey too.
I believe last I heard 65$/key.
Any more I feel lucky I have 2 keys. One on key chain that I carry and other in a drawer.
Some have used the key fob security systems, which are great once installed. But you have to remember when storing for Winter to put a charger on the X as that system uses the battery.
I personally, if I can see it when away from home done lock it. Other wise it's always locked.
