It's not just that RFID isn't very secure, it's that a lot of locks are using the worst possible implementations. Just checking the ID of the RFID chip against a whitelist is an astonishingly common method. Not only makes that access cards easy to clone and provides no cryptographic security at all, if you bulk buy access cards you often get sequentially numbered cards ...
OTOH I can use my credit card to open my door - and this is even advertised as a feature by the manufacturer!
Which lock do you have? I’ve been wanting to get one with this functionality but I’ve never successfully found a smart lock that works like that.
Mine is an Yale YMF-30
