I have the perms for all the vehicles set to default group and with a mini copter once i leave the bandit camp anyone can jump on it and steal it.

That's not what ownership means. If you want the vendor protection to last longer/farther, I could add an option to support that, or you could use another plugin to lock the vehicle.

I was also thinking about supporting a permission to automatically deploy a lock to the vehicle by integrating with the plugin for that. Let me know if you would be interested in that.

Oh sorry i misunderstood it, my bad. I have a PVE server so dont want other players stealing the vehicles so would definetly be interested in it, In an ideal world it would only lock the drivers seat kinda thing, so you can still give a fellow player a quick lift somewhere :)

If auto locking is added, it will require installing the plugin for vehicle locks to integrate. You can then configure that plugin to automatically share vehicle lock access with teammates, friends or clanmates.

The owner can also tell players the code or guest code, or craft a key, depending on the type of lock.

I tried Vehicle Locks, it doesnt work anymore. :(

Vehicle Deployed Locks, my new plugin.

ohhhh cool! Ill give it a try! Thanks 

It doesn't automatically add locks to anything, but one of my original ideas for the Vehicle Vendor Options plugin was to call the API of that plugin to automatically add locks when purchased from vendors (based on the permissions of the purchaser).
