Will this work on a Volvo or Prius?

No sorry, Keysy is only compatible with LF (125kHz) RFID. It will NOT work with any automotive applications.

My apartment complex has a gate card to open the gate and they only give one per household, can I copy an extra card with this?

If it's the type you wave in front of a reader it will probably work. If you can send a picture of the card to compat@tinylabs.io I can give you a more definitive answer. Thanks!

I have 2 access control systems, 1 (elevator) with hid prox and a door with em4100, can i replace the 2 fobs for a single one with this?

Yes, As long as it's compatible frecuency. The idea is that you can have 4 different keys in the Keysy. You press the number, 1 for elevator and 2 for door for example. Once you press the button, the keysy "becomes" that key, so you put it close to the reader and that's it. It has worked for me everywhere I go except my car park that uses a long range cards, kind of what road tolls use. Not proximity. Aditional to this functionality, I make keys for my guests , cleaning , etc.

Will it work with chevy vehickles

Although I do not know for sure, this is a passive fob, so probably not for doors or remote start that requires the push of a button. Also the instructions say it will not work with passive ignition systems for starting and driving. The four buttons on the Keysy are to select which of up to four stored cards or fobs are to be used.
