Emulation of mifare classic 1k intercom keys to a phone with nfc?

Question

NFC

Good afternoon, is it possible to emulate the mifare classic 1k intercom key on the phone, so that the phone with nfc opens the door, I have such a device SMkey, it receives a UID and a crypto key from the intercom, by the way, you register the UID in the device, apply it to the intercom and get a crypto key, if you change the UID, then the crypto key will be different. This device can do mifare classic 1k emulation, but is it possible to do this with a phone, if not, please explain why. The frequency matches.
