If the information I obtained is correct, inflatable airlocks are sealed by the air pressure and cannot be unlocked unless the pressure is lowered(correct me if I'm wrong).

Additionally, airlocks usually open "inwards". To be able to override this, they should open outwards, however, this will lessen its sealing ability.

Some inflatable airlocks are the MASH, AIA and LEIA. Also, I found a video on YouTube on operating the MASH. My apologies, I can't seem to find the link on where I read about the seals opening inwards.

Do inflatable airlocks that can be opened without lowering the pressure exist?

If not, is there any possible way to create this?

    $\begingroup$ It was an airlock. They had to keep air in the cabin to properly cool the vacuum tubes. (Seriously!) $\endgroup$

    $\begingroup$ @Zan you should edit your question and include that information. The less effort someone has to go to in order to figure out what you are asking, the better chance you have of getting an answer. $\endgroup$ Apr 29 '20 at 12:21

There's a fabulous overview of inflatable airlocks past, present, and future in this presentation

To actually address your question

Do inflatable airlocks that can be opened without lowering the pressure exist?

If you mean opening the outer airlock hatch without lowering the pressure in the lock chamber to near-vacuum....not really. Imagine what would happen if you opened an outward-opening hatch in that situation. Explosive decompression!

And why would you want to? The US airlock on the International Space Station scavenges much of the air back into the station so it isn't wasted.
