RFID Enabling Your Front Door

I believe Toyota uses TI's RFID system. Check out this site: http://rfidanalysis.org/
A team at Johns Hopkins University successfully hacked the TI RFID system. Just beware of security risks if you are using this for your front door.

 

I THINK the coding algorithms for passive and active RFID are the same, just the hardware that's different. Active RFID tag has a power source like a battery (our key fob is an active RFID tag), while passive RFID tag does not.

Don't have time to look at the datasheet on TI's website.. at work now... maybe tonight... Looks like the higher frequency kit is the way to go. Everybody in the RFID industry is moving toward higher frequencies, there gotta be some advantages right? One I could think of is smaller antenna, which means smaller RFID tag size.

Keep researching on this man, you have the coolest mod I've seen on a Prius so far. And I've been always interested in RFID stuff. It'll be interesting to see what you come up with.

What you really want is:
https://fjallfoss.fcc.gov/oetcf/eas/reports...nericSearch.cfm

And search for PENASAT2. Not the FOB's FCC ID. Since the fob is active and the FCC report didn't mention testing anything in the kHz range, you really want to read about the RFID readers.

The RFID readers in the Prius use 134.2 kHz.

The FOB's do not seem to have a rolling code or encryption. If you want to use your FOB to open the door to your house, then you just need to map the FOB's signature to some sort of authenticating system/micro-controller/whatever.

 

This sounds like a pretty interesting idea to me. Just when I was thinking that my condo doesn't have SmartKey...

 

The OP has a great idea. But it's been done already a hundred times over

. . . . . and then some.

But always with some other device. I want a uniform key system that activates the car, house, or whatever. Adding some _other_ device to do this isn't the point. It's all about integration.

.....and allowing a criminal to have access to everything you own with one item and leave no clues whatsoever......or requiring replacing all locks if one thing is stolen. It can be a great idea for some, and a disaster for others. Think it through like a crook would. The whole purpose of keys and IDs is security, not convenience.

I'd throw a brick through the window (like it was done by the 'crooks'). Locks and alarms are not meant to stop people from entering places they do not belong - just deter or slow them down.
Since the system would be 'electronic' you could change the 'lock' instantly. You could use and sms to disable the SKS for the house...

I'd just assume leave my doors unlocked but my cats know how to turn the door knob and get out.

I, unfortunately, have experience getting robbed. Many crooks do throw the brick, and many are very sophisticated, and many are not crooks till the easy entry tempts them into becoming one. The later one has been the biggest problem when keys are lost or doors are open. It is very common at Florida beach parking for a lookout and roamer to check to see which cars are left unlocked and take everything, usually purses and wallets easily grabbed. (Like the kid that went back to the car and forgot to lock it.) I am not questioning you doing what you want, since every situation is unique. I do know first hand that a good lock does make a difference, since it is finding the easy car to joyride or the easy house to pilfer that is the target....and I have learned how to avoid being the target.

I do not know... I have _way_ more trust in electronic locks than mechanical locks. I've 'bumped' all of my mechanical locks open in under 45 seconds. The only lock that I haven't been able to bump are the magnetic keyed locks.
