It is very unusual to have an air lock in the system. That would indicate a large amount of air to effectively block the flow.
When the system is on and calling for heat, you need to check which parts are cool and which are hot, although if it is close to the boiler outlet the whole system may be cold, including your hot water cylinder.
Unfortunately you have not described what type of system you have, if it is one of the modern pressurised systems I have no experience.
On the high points in the system there should be vent valves usually on the end of stub pipes. Suggest you locate these and bleed from there (as well as the rads). If the system is old, you may have a blocked feed pipe from the header tank, in which case it will not make up water, the boiler will vent into the header tank, and as the system cools, instead of make up water from the header tank, the vent will suck air in, and then you are on a hiding to nothing unless you fix the blocked pipe.
Sorry but without a bit more detail from you it is difficult to diagnose

Find whichever of your radiators is not getting warm to the top then loosen the small plug at the top until you see water coming out. The rising water will have pushed all the air out.

start at the rad. furthest away from your furnace, bleed that rad. and work your way back to the closest rad to the furnace. this way you will not get the problem again. and when you bleed each rad. make sure you bleed it long enough to get all the air out, i usually bleed mine until i get about a pint of water out.

Go around all you rads and check which is hot and which is cold. Check the pipework as well. this way, you can locate the area where you have an airlock.
