TR4/4A TR4A Trunk Lock

The prior owner gave me the key for the trunk but it won't move the lock. Apparently, by turning the key, two little stopping blocks protrude and prevent the handle from turning.

But for mine, either the keys are wrong or someone replaced the lock and not the keys.

Here are two pictures. Can anyone tell me what that after-market pin is doing over there to the left near the shoulder. It's clear to me that a brass or copper pin (you can see it shining--not the roll pin to the right) has been rammed in there for some purpose, and I'd suspect a locksmith will need that pin out to remove the key spindle.

Any great thoughts?

In my experience the handle should be purchased new with keys since it is not worth the trip to the lock smith to get the work done.

I don't believe that is an aftermarket pin, that is the pin that holds the lock cylinder in place. But it has been a long time since I had mine apart.

If you want to rekey the lock cylinder, and are not super concerned with security, you can take the cylinder out, put the key in that you want to key it to, and file all of the pins down. That makes it so that many keys will probably open it, but it will still lock to stop casual curiosity.
 
I cannot recall -- is the key number stamped somewhere on the mechanism? Would probably be 'FS nnn' -- if so you can often buy pre-cut original keys from one of the 2 vendors of Wilmot Breeden old stock.
 
The key number is stamped on the lock cylinder, so you have to drive
that brass pit out to release the cylinder. Darrell Walker's method is
the least expensive way to go.
 
Thanks guys; I did what Darrell suggested. I drove the pin out, pulled out the tumbler and could see that no matter which key I inserted, two of the pins just remained stationary. I carefully filed them down and now I have a nice locking trunk.

Thanks for the help!
 
I was pretty sure the trunk had the key number stamped on the shaft but I'll have to check to confirm.
