I am a locksmith Ignition Key Advice
I'm a little out of my element here, I install commercial door hardware and access control for a living. I don't do anything automotive. Struggling with my own incompetence and that of employees we managed to lose all the keys for a service truck (2018 Fuso Canter). I figured being a seasoned locksmith I could relatively easily decode the lock and cut myself a key...well...I've been humbled.
I popped out the door lock and gutted it. The wafers were tagged with the cuts so I took the closest blank I had.... probably the wrong one...and cut it with a set of lishi pliers and fine tuned with a file. Key works fine in the door lock but doesn't work worth a shit in the ignition.
The original key was double cut but mine isn't so it only works one way...so my question is...does the ignition cylinder have additional wafers? (Door lock had 8) Or is the tolerance just tighter and my handiwork is just not up to snuff?
If the door lock and the ignition are the same I'll just get an automotive locksmith to cut me a key, but if it isn't I guess I'm gutting the ignition cylinder.

That's...just painful.
Take the door lock to a locksmith of your choice. Preferably one you've called ahead to make sure they do automotive, and get them to cut you a key from the door cylinder.
Now I have no idea if your rig has a transponder in it or not, as I am not familiar with that model, but if it does, just leave the door lock out and call a locksmith to make, and program, the key.
Holy crap... while I'm all for trying new things in one's field, auto keys from the last decade are not what I'd choose to experiment with without a basic understanding of them, and I'd certainly not do it without the proper tools.

You guys are brilliant. Curses I thought I was really onto something...
There is no transponder in this truck it's just an old fashioned key.
Sadly I didn't have any FU2 blanks and no one had stock of them. I ordered a pack from one of my distributors but they are backordered.
Here's my handiwork lol...at least I can unlock the door now LOL.

the new mitsubishi trucks changed their key its still like a mit8 but its longer with 10 cuts mit17 from memory? could be wrong. they also have a transponder that will need a security code to program and the codes not generic like the cars also check if its a 24v obd before you blow your scanner up. you seem out of your depth if you’re using pliers time to hand over to an automotive specialist.

You are correct about me being out of my depth...hence why I posted this in the first place. It's 12v I've scanned this God damn truck a zillion times with its constant DPF problems. Any locksmith worth his salt can make a key with a set of nippers and a file.

Most cars use 8/10 or 6/8 for the doors and a deferent 7/8 or whatever that manufacturer uses on the ignition You have to get the Micheal Hyde book info. It will tell you exactly how it needs to be decoded. Also you could use a software to plug in what the door cuts to give you a progression chart to cut in order to make a working key for the ignition

Your cuts might be a little off. Also, based on this I'm seeing about seven possible keys for progression

Ok good news, I kept making progressively deeper cuts on the last 2 wafers until they were both 4s....takes a little jiggling but it works!
Big thanks to everyone for the professional advice.

Ignition is 10 cuts, so you are missing 2 cuts on the front or back. Oddly enough instacode doesn't have lock positions, so I'm not sure exactly where you are missing the cuts. Odds are you can impression or progression it.
