The second-hand house I bought has been transferred and the balance has been paid to the landlord's account. We agreed to hand over the keys today, but the landlord didn't answer the phone and never showed up.

If it has indeed been transferred and all the payments you need to make have been paid, then you should also confirm whether there are any unpaid expenses by the original owner, such as property, heating, water, electricity, etc., if they have all been paid. If it is cleared, you can directly replace the lock cylinder. If there are still remaining problems, then find an intermediary to coordinate and resolve them. If nothing works, then find the media to expose them. If you really care about it, don’t worry, there are always more solutions than difficulties!
