How to open many keypad-access doors

3/11/2009

Here's a fun little tip: You can open most Sentex key pad-access doors by typing in the following code:

***00000099#*

The first *** are to enter into the admin mode, 000000 (six zeroes) is the factory-default password, 99# opens the door, and * exits the admin mode (make sure you press this or the access box will be left in admin mode!)

I'm not sure how prevalent they are, but here in San Francisco, Sentex building access systems seem to be the most popular.

@jim: what do you mean, WTF? As in, David was wrong to post this? As in, Sentex was wrong to provide this feature? Or, as in, companies using Sentex building access systems are wrong because they haven't removed default passwords? WTF indeed!

Pretty use of jparallax. Hadn't thought of using it like this (instead of the more typical landscape/skyline layers).

Nice picture! Reminds me of South Park Colorado. I used to drive thru there all the time to get to Breckenridge from the south side of Denver. Also looks a bit like the high Sierras around Bridgeport, California.

Oh, that south park route. fscking boring... but at least you can hit 120 without too much worry. :)

That's really nice about the shiny, cool header and all, but let's talk about the content.

Has anyone tried this and verified that it works on any keypads? How many installers have not changed the default passwords?

I've never seen a Sentex brand key pad. What types of installations are they standard at? To which markets do they solicit the most? Apparently these keypads cost $325, so it's pretty economical.

Can anyone confirm the effectiveness of this exploit?

That header is awesome!

As for the point of this article, that's an unbelieveable security issue, but I suppose people will be too stupid to reset admin passwords and such...

Where I work I have found that any combination of the letters and numbers in the door code can open it fine,
so if it was 1234, you could use 1324, 2341, 4321, 2314 etc....
Kind of stupid as it means the chance of guessing it becomes much higher...

Default codes should be changed by all administrators to prevent unauthorized access. The default code is for programming only and not intended to assist others with unauthorized access.

Such locks should come with a warning label for customers warning that the default setting must be changed before use.

I'm really confused why people are so fascinated with the header. It's just the jParallax plugin. I'm guessing a lot of you are new to the Internet.

Want something really impressive? Go look up the HTML5 canvas tag and take a look at what people are doing with it.

Okay with that outta the way, cool exploit! If only I knew of some places that used a Sentex keypad I would try this out.

After 10 minutes of reading the comments I went back up and checked the header. I'd missed it first time round but it sure is awesome.

WOW

Confirmed! it works! I've tested it on 2 buildings downtown and one of the passwords have not been reset. any links to the manual for the other codes? it's quite interesting.
