Duplicating this RFID key (pics)

What is the difficulty to duplicate this simple RFID key fob? It is my key
fob to enter my secured building and to call the elevator. I'd like to have
a spare without going through the building management.

It's a very tiny chip asa you can see. Is anyone familiar with this? How
difficult would it be for a security business to identify the RFID code the
chip puts out and program it on to a generic one? Here's two pictures, one
of the fob then another of it when seperated:

Yeah right. We might believe that is the real reason for wanting a
duplicate, but I doubt the police would when one gets lost and is used to
break into the building.

 

Why would I want to break in to my own building? A friend will be visiting
soon and I'd like to have another fob so he can come and go as he wishes
while I am at work. I was just asking a simple question, if you don't have
any helpful advice don't post, please.

 

Can we all have one, while you're at it? Might as well, we might need one
one day.

You could ask someone to leave a spare under the third flower-pot on the
left, or even better fix things so that you don't need the pesky key at
all. After all, the nonsense about 'security' is just a lot of hype to
scare people into wanting locks and so on. There really aren't any
unauthorised people wanting to get into your building. No-one at all.
I'm sure the management would understand and reward you for your
public-spirited initiative.

(Keys that can easily be copied 'without going through the management' are
not 'secure').

 

Pretty easy if you have the right equipment. There's a article in
Wired about it.

But if you don't have the hardware... :-D

 

Apart from security implications, another issue is fire regulations.
Those devices can be read via a phoenix interface (google it), and
then a "duplicate" produced. But it is probably assigned to you and a
specific number allocated, which could leave your "friend" trapped
in a burning building with evacuation records showing empty.
Conversely rescue officers could be put at risk from your dubious
folly.

 

I know I do not have the hardware, otherwise it would be as easy as the push
of a button to program the proper string in to a stand alone 125khz chip.
I've called a few local security places but they are all closed today.

These keys only work for entering the building. You swipe the key when you
want to get in. After you are in, anyone can call the elevator to go down
and walk out the door without any key.

 

Closed on a Friday? That's odd.

Yeah, I have one of those too at the building I work at.

 

If it is YOUR building (which I'm guessing means you RENT there, not
own), call building management. That's what you pay them for isn't it?

 

Go through the building management.
