Not sure this is such a good way to do it.]]>Dec 19th 2005 1:26AMhttp://www.engadget.com/2005/10/04/how-to-set-up-keyless-entry-to-your-house-via-your-cellphone/http://www.engadget.com/2005/10/04/how-to-set-up-keyless-entry-to-your-house-via-your-cellphone/
I have a door buzzer for my condo, but I can go more simple, since I am the front unit and a simple RF keyfob and contact should do the trick.

But I wouldn't have thought of it until I read this.

Would have been fun to try and hack it into the security switches on campus last year.

I would really love to figure out a way to use the 2nd vehicle switch on my car alarm to unlock my apt door.

I think it would be only of medium difficulty more mechanical than anything. If I could actually hack my door apart I would try it. O well the cons of renting.]]>Dec 19th 2005 1:26AMhttp://www.engadget.com/2005/10/04/how-to-set-up-keyless-entry-to-your-house-via-your-cellphone/http://www.engadget.com/2005/10/04/how-to-set-up-keyless-entry-to-your-house-via-your-cellphone/

Most appt buildings have buzzers to get into the building, not your apartment. Most actually have two separate doors to get inside. You have to get one set of keys for the outer doors, then once inside, you have your own appt key. This is highly annoying, especially if you're carrying something.

And, I'm sure more than 1% of people that read this live in buildings such as this. Pretty much every building in all large cities (NY, SF, Chicago, etc) is set up like this.]]>Dec 19th 2005 1:26AMhttp://www.engadget.com/2005/10/04/how-to-set-up-keyless-entry-to-your-house-via-your-cellphone/http://www.engadget.com/2005/10/04/how-to-set-up-keyless-entry-to-your-house-via-your-cellphone/
It would be wiser to at least base this on matching Caller ID. Although CID can be easily spoofed it's going to probably be secure enough for building access where plenty of other things are less secure (tailgating, everyone else who lives in your building, etc.) There are uC's and plenty of samples out there for reading CID info and you could easily have them click a relay for you.]]>Dec 19th 2005 1:26AMhttp://www.engadget.com/2005/10/04/how-to-set-up-keyless-entry-to-your-house-via-your-cellphone/http://www.engadget.com/2005/10/04/how-to-set-up-keyless-entry-to-your-house-via-your-cellphone/Dec 19th 2005 1:26AMhttp://www.engadget.com/2005/10/04/how-to-set-up-keyless-entry-to-your-house-via-your-cellphone/http://www.engadget.com/2005/10/04/how-to-set-up-keyless-entry-to-your-house-via-your-cellphone/Dec 19th 2005 1:26AMhttp://www.engadget.com/2005/10/04/how-to-set-up-keyless-entry-to-your-house-via-your-cellphone/http://www.engadget.com/2005/10/04/how-to-set-up-keyless-entry-to-your-house-via-your-cellphone/
On a simmilar note Silicon Chip magazine here is Australia had an article on how to control your home using SMS

http://www.siliconchip.com.au/cms/A_102670/article.html

It works by pulling SMS codes from a dedicated Nokia phone on a prepaid plan, and activating outputs. You can therefore have multiple SMS codes (in plain english) control different tasks, such as sprinklers, aircons, doors etc.

The controller also works in the opposite direction, by SMSing you when an alarm is triggered.

The kit is available in various places such as http://www.dse.com.au for about A$65 (US$40ish)

The diode is so that the ELK board doesn't get fried when the electric lock switches off and sends a massive current back along the wire. It's called back-emf.

I use a combination of a relay with asterisk.

Using asterisk allows me to protect opening of the door via a series of passwords entered on the phone (DTMF). This means that only those with the passwords can actually open the door. It also means I don;t need to sign up for another service since I can call in on my standard PSTN line.

It's also worth pointing out that there are lots of services that will give you a FREE pstn number and route it to your sip proxy/asterisk box - that $56 could be better spent on more gadgets!

it's a separate phone line. the door won't buzz every time he gets a call.

that people could open the building's front door (note, not his apartment door) by calling that number is true, but no one but him knows the number. This to me is the equivalent of a seven digit code on a keypad. No one's going to guess it.

Lastly, yes, it would be easiest to just open the door with a metal key. But we wouldn't bother to read about that, now would we?

The thing about someone patent this is rediculious, I have been in this industry (electronic security) for nearing 20 years and this is nothing new (telephone entry, DTMF to Relay)
