T120v Dismantle Ignition

with some of those you have to insert the key, turn it, and then poke a wire through a hole to free up the cylinder. im not sure about yours, but its a general procedure.

can you pick the lock? most of these older key locks are pretty easy to turn with a couple of basic picks.

take the switch off so you can see all around the housing. once you get the cylinder to rotate, you can poke a wire down a hole to depress a plunger in teh cylinder that holds the cylinder in the housing. the plunger will not line up with the hole unless the cylinder is rotated.

If your lock has some numbers on it it's likely to be the key number. Second choice is send the lock to someone like 1st Metro key Locksmiths and they will find you a key. Just did the same with my executive luggage which has the same lock as the steering lock. Or gently drill it out a little bit at a time save futtering. Welcome to the family by the way.

or take the whole thing to a locksmith and say, make me a key

Hope you get sorted. And you know a complete new lock isn't all that expensive.
