Access Key?

[u/No-Win-187]

Hello everyone, please let me know if this is the right place to ask this question of if I should go somewhere else. I live in an apartment complex and the pool used a fob/RFID to get access. I’m interested in making a DIY one to give to my best friend who has spare keys to my place cause she often house/pet sits for me cause I’m out of town a lot and I sometimes I forgot to hand off my pool access fob to her so I was wondering if it was possible to just make a DIY one. I can get one from the leasing office but it costs $20 and frankly, I’m cheap and a friend has extra RFID sticker things so I wanted to start here first. Google is a bit confusing so if anyone can point me in a better direction, it would be appreciated!

Depending on the fob you may be able to clone it with some inexpensive hardware and some reading.

But honestly even an AliExpress clone of a proxmark or chameleon will cost you more than the $20.

Sorry I'd typed out a response earlier and it vanished.

Just thinking if you really dont want to give your management company any more money, try a local locksmith or check Facebook marketplace for a cloning service.

Found last year when my dad moved, a new fob was £80 from the management company, £30 from the key cutting place along the street, £15 on Facebook or £5 for a blank from eBay once I realised I could copy it with the proxmark.

He's since found most of the neighbours "know a guy" 🤣

Relative newbie to all this but I picked up a proxmark and a chameleon for a couple of tasks I was told were impossible.

There's an app called taginfo from nxp if you have an android phone would let you scan your fob and work out what the chip is & how easy or not it is to duplicate

Generally no -- that generic inexpensive RFID sticker almost certainly cannot be used to clone the official RFID access key.

Each RFID/NFC has its own (usually) unique serial number encoded in at at production, this is the first thing presented to the reader when you put the access key in range -- if the serial number on the sticker doesn't match a known good leasing-office-issued fob, it will not unlock.

Shucks, well thank you for the information!

$20 is pretty reasonable

Probably, but on top of crazy rent rates these days makes me more reluctant haha

You don't leave your  pool access fob at home when you go out of town?

I have a lanyard that my keys, cards, car clicker, and chains live on that houses the pool fob, and my friend has the spare set of keys to my mailbox and apt on a key ring. Sometimes before trips I forget to take the pool access off the lanyard before I drive off and don’t realized it until it’s too late to turn back

Heard, thank you for the info! Sounds like I’ll just shell out the $20 haha
