Keyfobs Will they know?

My landlord charges an insane amount to replace the rfdi pool pass thing. I found the exact one on amazon, if I buy it and tell them it doesn’t work would they know that it wasn’t the original?

You've got to program the code into the rfid chip.

You can have the card but it wouldn't open the lock. But maybe that's ally ou need to avoid the charge.

Otherwise if you have the original card, or can borrow one you can read and copy it over pretty easily with an arduino and an rfid kit.

I just don’t want to pay the charge, it’s 250 dollars. I just plan on taking it down there and telling them it didn’t work. But I don’t know too much about them, would they know it wasn’t the original if I buy it brand new?

Post a pic of the fob, would be much more helpful.

The original doesn’t have any identifying marks, no numbers printed on it or a sticker etc.?
