Does anyone know how to get the top off of a McCormick Sea Salt grinder to refill it?

I’ve been trying and trying to get the top off to refill it but nothing has worked so far. I managed to get the smaller lid off no problem.

I’ve tried squeezing and twisting the main cap, nothing. I’ve tried using a butter knife, to no avail. I’ve looked underneath the lid while I was forcing the top up a little and it looks like it COULD be pried off with quite a bit of force.

I’m thinking I’ll have to use pliers or something to force it off? I don’t want to have to buy another sea salt grinder just to have another bottle.

Any suggestions?
