It would probably be easier to remove the meter movement from the instrument and there should be small screwdriver slots to pop the lens off.
Be extremely careful, as meters can be damaged easily.

I have two of these, and I looked at them yesterday to see if the meter cover would pop off. I used a fair amount of force, and neither budged. I was afraid to try to pry them off.

Hopefully, they weren't glued on! That's why I suggested removing the meter. It would be a little easier to see what's going wrong.
BTW, 5 bucks was a good deal!
