On this video we are using a 1.5mm Allen Key and a small hammer to gently tap on the key. As you can see the valve is not very deep inside the thread and you can usually use either sides of the Allen Key to reduce the force.
Each time you hear the gas escape, some force is reduced. On small gas springs with a small gas chamber the force goes down quickly so you should go slowly and make as many trials as necessary.
The product shown on this video is a 250mm stroke gate gas spring.
