Old Medco double key deadbolt removal.

Hello everyone. First time posting. Hope someone can help me out. I have an old Medco double keyed deadbolt which I'm guessing is around 25 years old which I'm trying to remove. I've tried to post pictures. Thank you

You didn't say if you have the key or not. If you don't have it, you probably have to drill through the cylinder.

Sorry for not mentioning it, but I do have the key!
I was unable to find any kind of set screw. I looked for a small gap beside the deadbolt as well (saw online about someone putting a small allen key in there) but didn't see one. The flanged outer rim of the deadbolt in the picture does rotate with a pair of channel lock pliers, bit it is very tight.

You should see 2 small holes on the other side. Turn the key a 1/4 turn & insert a small Philips screwdriver. Unscrew the two screws. Remove both cylinders. Then you can remove the side piece.

I've added some more pictures of the outside of the lock and the edge of the door

So I was able to find a small circular "spring" on the outer rim of of the cylinder between that and the tapered "shroud". Sorry but I don't know all the proper names for these things. After removing the spring I'm kinda stumped as what to do next.

That wire spring holds the inner cover into the face of the cylinder. Usually, once the wire retainer is removed, the cover just falls off, to reveal the 2 allen tie screws, but after many years, the cover is likely to be stuck to the face. Use a tiny screwdriver or similar to loosen the cover and it will come off.

I can't tell from your photos, but the retainer is used on the INSIDE cylinder, as otherwise the lock could be removed from the outside. The photo is sharp enough tho that I recognize the keyway as "AIR" which was the original patented keyway from the 1960's, so yeah, that's an oldie!
