That key has quite a complex mechanism - the "very thin piece of metal" is a flat spring, springing the key shut. That appears to be working normally. What you don't see is the much smaller flat-spring, attached directly to the pad armature itself, which is meant to spring the key open when the larger flat spring is depressed.
The RH mechanism physically lifts the key against the closing force of the large flat spring so you don't notice the problem there.
The problem you have could be caused either:
1. by excessive friction, either a dirty rod or the two posts being too close together and grabbing the key, or
2. by an overly weak small flat-spring.
The first thing I would try would be to take apart the long LH-pinkie feather-key assembly to access the Eb tone-hole. Then I would clean the key, its rod and posts, check the spring is curved well, and then I would reassemble it and check that it is flipping up correctly. But I understand if this is a little unnerving ..
If you DO decide to try this yourself, please be aware that you need to undo the long feather assembly from BOTH ends. On some oboes there is a loose ring next to the Eb key that holds the keywork in place (e.g. Marigaux) while on others (Loree) it is just a saddle-like affair on a post. Release needle springs first!
