batterysmoke-detectors
First of all, I'm a bit embarrassed I cannot figure this out myself.
I have looked up Youtube videos, Google searched but I didn't find any exact video.
Plus I have tried pressing it hard, lifting but it seems very hard – just hurts my thumb.
I don't want to call an electrician or tell my landlord but I can't sleep with this chirp going on as well. Can anyone help?
Wow- A smoke detector that could cause a fire..
It is very difficult to say
It could be a fault in the fire alarm- short circuit that caused the battery to heat up to a cooking point.
It could be a chemical fault in the battery where atmospheric pressure and chemical imbalances caused by some impurity during production caused the battery to heat up at a certain point of its life.
Either way
The safest option is to replace both and remove all doubt!
eg ever hear about the exploding iPods... :)
My suggestion is that you try pressing in (or up) on these two tabs:
And then that the lower part of the unit will hinge down. The hinge edge being along here:

Push the tab toward the arrow and then lift it up. Good luck
