Aluminium Patio Door Lever Problem

Wanted to replace a euro cylinder on my mum's patio door as she's lost her key.

Drilled it out and removed cylinder.

I've been searching all over the net for the correct terminology and have drawn blanks.

It appears to have a pin on frame system and I think it might be an old Boulton and Paul patio set from the mid 90's.

It had a Yale lock which was keyed both sides.

The patio handle set has a lever below the euro cylinder.

So to open the door, you needed to turn the key and then move the lever up.

So the bit on the euro cylinder (don't know its name) rotates and stops the levers being moved.

The 2 point lock looks like keyholes and the lever on the patio handle set actuates somehow and slides the keyhole up to secure the door.

My problem is the lever now doesn't want to move its full travel and the circle of the keyhole is not fully visible so I cannot even close the door now!
