Have you tried to scratch away the paint from around the square head of the vent? This allows the vent key to grab the vent head all the way to the bottom. File your vent key so the bottom surface is flat. (see the attached pic). Place the key down onto the head of the vent and push the key with your thumb as you try to turn the vent. Don't force it as you may damage the vent more. If it won't open by hand you can use a pliers on the head of the vent key and again push down on vent key with finger as you gently try to turn the key with the pliers. Don't force it, make sure the key is getting a grip on the head, if the key gets a grip gently twist while pushing down to help prevent slipping.

Failing to get vents open:
Their standard vents, you should get them is any good plumbing suppliers. I think they're 1/4", if you close both rad valves, "make sure you count the turns on the return valve so you can open to the same point after fitting new vent" and take out the vent. You will be screwing out the complete vent. Scratch away paint from around the head and use the correct spanner, again gently twist while pushing down with a finger to try and prevent the spanner slipping. If the vent body is too tight you may need to gently heat the rad around the head using a small gas torch.
TIP: Next time you paint rads, don't paint over the vents. When closing vents just give them a little pinch, just enough to stop water passing. Some people go king kong on them thinking it's a car wheel their tightening.0 -
