Having a tough time turning the trunk lock in my 66 Convertible.
Replaced the latching part that mounts to the body but problem the same. The tumbler itself seems to turn fine as does the latching mechanism.

I'm wondering if the shaft is going too far into the latch?
When I open with a screwdriver, I've noticed I can open easily as long as I don't insert too far

Thanks for the help

The typical 'trick' is to push down on pointy end of lid while turning the key.

In particular if the rubber weatherstrip is fresh.

Need to check clearance.

The shaft between key and latch can catch on sheet metal.

New gasket between trim and sheet metal?

The adjustment for how tight the trunk lid latches is on the lid, not the latch. Too tight and the key is hard to turn. Too loose and water gets past the seal. Balance.

Now, if the key is hard to turn with the lid open, something is binding in the latch/cylinder assembly. The "tongue" from the cylinder to the latch, does it limits its travel by hitting the latch? It should just slide into the latch and is stopped by the front grille bar/cylinder/tongue attachment spring. There is no too far unless there is a binding that stops it (tongue) from entering the latch more. Sometime prior bodywork moves placement of this assembly around more than the designers thought about on the assembly line.

I would say check for a bent tongue, but without a known good one....

So, hard to turn key lid open or closed? That is the first question.

Do not think so.

If you have a new shaft, you can cut it off even with the back of the latch if you want.
