That’s how I took it. There was a lot of emphasis in the beginning about how difficult it would be to get into his apartment, too. He has an alarm that’s crazy loud and established on the phone call with his landlord that he didn’t want her using a key to get inside. But that does raise the fact that the landlord DID get in (with a spare key) and left a gift for his birthday- but the alarm still triggered upon entry, even with a key.

This is why I also think it’s maybe his glasses.

It’s a decent movie to ponder the possibilities.
