They are made using a nickel silver blank so won't rust like the old steel ones.
These work great in my reproduction cylinders.
Also have used them in some of my old original switches and they work fine, you may need to do a little file work depending on how worn your old cylinder is. If it won't work you can return it.
The cost to DMAC members is as follows:
With my new replacement cylinder total for key and cylinder is $ 65 post paid In US and Canada
If you purchased one of my cylinders the key is $20 postpaid In US and Canada
If you just need the key the cost is $25 postpaid in US and Canada.
I will ship to other countries but add $2.50 for postage
It's been a long time since these keys were available, they work on other old cars that use the Clum switch.If you could find one the price has been very high. At the present time they are only available to DMAC members .
Let me know if you want one and I will send it out with a bill.
