Unfortunately no. Depending on how the apartment complex uses the memory in your 4k classic chip, it might be possible to clone the ID and first 1k of memory to an xMagic or xM1 and have it work. Can you scan the memory of the chip in your keycard with taginfo and post the full scan here? If all the latter memory blocks are basically factory untouched with default keys, then there might be a chance it can be copied and used with your apartment complex.
