Hacking your apartment's electronic entry system

An apartment I lived in had a similar system. I noticed that the caller ID showed what appeared to be a valid number. So one day I tried calling it while at the door... when it started ringing, I started hitting buttons on the keypad (on the door) and when I hit the # key (or maybe it was *), it picked up. I was then able to dial 9 from my phone, and it let me in.

I no longer live there, and don't have access to an apartment that has one. I'd be interested to see if that works on other systems. If anyone wants to try, let me know if it does.

I just realized that my system appears to work the same way. I always wondered why the caller ID showed a different number for my buzzer from the rental company main lines, so I'll have to program it into my cell phone and see if this works for me.

Great insight, my mind never jumped to this idea. I was thinking of putting the '9' tone on my answer machine.
