Suggested correction: Maybe Squidward has a key to the Krusty Krab that Mr. Krabs doesn't know about.

Absolutely not. There is a very clear shot of Squidward pushing the doors open without a key.

He could still have a key, but we don't see it.

Whether or not Squidward owns a key to the Krusty Krab is beyond the point of the mistake here. The point is that Squidward is able to walk into the Krusty Krab despite the doors being locked, and he doesn't use a key or anything else to unlock them. He just pushes them open.

Maybe the doors were not locked properly.
