,,, and if so does anyone have a pic of one and dimensions? Our panel has no key so I have been bodging it with a thin screwdriver. We can make one if we know what they look like
 
On our old boat with a 2GM20, my dad occasionally switched it with the shed key when he didn’t have his glasses on. I don’t know if our lock was particularly worn or if they all turn with any flat bit of metal, but they are certainly not a high-security item :)

(I later replaced the key switch with a simple rotary switch for convenience and to avoid having a bunch of keys dangling in the companionway. No need for security since the panel was inside the cabin.)

that is probably going to be first thing I will try, there are dozens old old keys here, it one isnt a straight fit a quick file or grind should do the trick now I know the shape

I used to have a Capri like that :)
 
I've always known them as tractor keys. Try Google for Lucas tractor keys and you will get about ten for a fiver.

PM me an address, I think I have one you can have. Its not a genuine Yanmar one, but I'm pretty sure its off the 1GM10 I had fitted in my previous boat.
Will also check wifes spare set of keys, she may have one too?
 
In the early 70s I returned to my ford Anglia in an Oxford car park after work. Put the key in the lock, opened it, got in and prepared to drive off. I then noticed a trilby hat on the passenger seat. Not being a hat wearer, I realised I was in the wrong car and beat a hasty retreat. Maybe all fords had the same key.

In the 70s as a student I was able to unlock my MkII Cortina with my thumbnail. My 1GM10 key broke within a year of being installed (I think I kicked it) and for the last 20 years I've used the same bent screwdriver .. far more robust, and doesn't protrude as much as the key did.
