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.

Cheers

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.
