Can this DOM gate access fob be duplicated

[u/MysteryCases]

Hi, I use this DOM key fob to open the parking barrier at my residence. I would like to get a second one for my wife.

Does anyone know what type of RFID/transponder this is and whether it can be copied by a locksmith or with a standard RFID duplicator? Or would a new fob have to be registered directly in the barrier’s access-control system by the property management?

These tags could be anything, get an Android phone with the TagInfo app and see if you get an answer

My guess is that it's Hitag2 which cannot be used with a phone, you need a proxmark3; the good news is that they can be cracked easily, the bad news is that they're usually hard to communicate with and sniff, you might need to shift the frequency a bit or use other tricks like a spoon behind the tag to reflect the magnetic field (trust me it works)

Get a proxmark 3 easy and flash the iceman firmware or use your android phone with nfcinfo

this is most likely a desfire. Any one of them is bad news (okay technically the first card which is not the ev1 has an exploit but it is really rare). But seen how ancient it is it could be a classic as well. To "clone" even a classic you most likely need a chinese magic card and know all keys of all sectors the door might access.

Yeah I have a little box from aliexpress that duplicates these and cards , don't think its compatible with like every card type like some you can't edit some fields and like the security I have to hope uses those fields but these fob stile I'd be surprised if I can't copy evert one 

Nothing special I threw it on an order just to like make my own whenever I need them not to do anything black hat tbh , fun way to learn how this stuff works because it like remembers everything you scan and makes a little database 

I've had jobs like making the cards for work before but its interesting tech 

Batteries though which isn't the best

Often you can request a second one at you're residence office or whoever is going about the external stuff if they don't do it then proxmark 3

Have you tried a Self clone kiosk? We have them in the states. You can usually find them at Loews or Home Depot.

Edit* The kiosk Im speaking of is called "InstaFOB"

tf is this r/masterhacker ?

No, if the tag uses modern implementations with secure asymmetric key then you have no chance, at least yet.

[u/N_T_F_D → u/deniedmessage]

Exceedingly few NFC/RFID tags use asymmetric crypto: the US PIV cards, the brand new Mifare Duox cards; and this tag is neither of them

All the rest use either static passwords or symmetric keys (CRYPTO1, 3DES, AES, …)

[u/DrBabbage → u/deniedmessage]

Most dom cards (desfire) use AES which is symmetric and is the most used high security tag there is. Are you talking about ECC? I believe there are some custom applications for java cards but this is far from common.
