Any RFID experts out there?

I lost the dime sized keypad fob for the home alarm system from my key ring so now have to use the number pad. The security company says they're obsolete but can replace the keypad and give us new fobs for about $700.00. For that I'll punch numbers.

However my wife still has hers and I was wondering how generic these things were. Are there aftermarket ones that can be programmed? Anyone know how the system works?

Also the new fobs are the size of garage remotes. NOT a plus.
 
We use RFID at work for our machines. They can easily be programmed and re-programmed over and over again. We don't have the fob type but when I get in tomorrow I will ask the guy who buys them for the contact and maybe they can point you in the right direction.

Thanks. I can make a holder if I can find an appropriate disk. It was on my to-do list but a bit too late now. The disk popped out of the plastic holder and this time I didn't see it drop.
 
Frequently it isn't a case of programming the fob, but rather programming the alarm system to recognize the code on the fob. Do a little searching on the 'net and see if that's the case with yours.
 
The techie from Chubb indicated that if they had them they could be programmed to my keypad. I'm not sure how many variants there are apart from size. Mine was a contact device but some are proximity. The whole RFID scene gets very scary when you read up on capabilities. Tin foil hats and all.
 
AFAIK when you buy RFID fobs, the code for each fob is fixed. As Rob said, you just have to tell the alarm that the old code is no longer valid and the new code should be allowed access.

That kind of sounds logical but as it's totally out of my realm I can't argue with Chubb's techie or system.

FWIW, It's a Chubb system and I can't see any other label on the keypad and don't know if other alarm companies use the same parts.

Check your billing and see if they list the Chubb model number for the system. It seems that Chubb just re-badges systems from other companies. With that, and a quick internet search, you should be able to find the OEM model number. That will give you something to use, to search for the manual.
 
Someone who holds an RFID+ certification would likely have the knowledge and resources to help you with your issue. From what I've read you can reprogram the security system to recognize a new RFID device but the trick is to know how to do it. It might be a bit of a challenge locating any service manuals for the alarm system as this information could be used for illegitimate purposes.

Barrng a miracle and finding the fob don't see any easy or cheap out, partly as you point out regarding potential misuse issues. Punching in the code will work until we can justify a new system. We could get a new system on contract for what they want to just change the keypad.

The annoying part is that the disk popped off the holder a couple of times and I was going to make a bulletproof holder tomorrow C'est la vie.
