unican button locks

[Chucklz]

I guess I am having the most trouble describing what I do, because its been quite a while. Looks like I am going to have to hunt down a Simplex lock soon. First off, I always try the factory combination (24)3 first. Seems silly, but apparently for many years a very large user of Simplex locks, used the default combination. While I hope they have changed this, I fear that they havent. If a large corporation doesnt change the default combination, I assumed that most people wouldn't, and with my friends lock I was correct. Once he changed the combination, I tried to determine how far one of the tumblers needed to move. After determining just that one tumbler, I used that information to brute force the approximately 300 combinations that were left. I only needed to do about 20 before It opened.

Other bits of info that I would like to postulate for the average Simplex lock

1.) Joe User will almost never set a one push combination, be it a single, or multiple button push.
2.) (12345) also seems "insecure" to Joe User, and probably is never the combination
3.) Joe User will probably pick a 3 push combination. Think about what you would do if you were ignorant of picking, and went to set your lock. I guess that most users would pick at least one double push, but almost never a triple push. The default combo contains one double push, so Joe User probably things that this is a clever thing to do, and that any more than a double push will limit his possible combinations

While these are not hard and fast rules, and certainly if someone knows a bit about Simplex locks, I would assume they would not pick a "routine" combination. But, as these locks are used for high traffic areas, the special pushes would probably become inconvenient to demonstrate to most users.

Of course they're going to tell you that it's extremely unlikely. They wouldn't admit any weaknesses in their design! In any case the "2+ number combinations" shouldn't make any difference. One would still figure out the position of each tumbler individualy, which isn't affected by whether or not multiple buttons are pressed at a time. And "1+3 then 2+5 then 3" isn't a valid combination. You can't push any button more than once.

1. That is actually an incorrect statement. The combination for the Unican series of combination locks IS affected by whether a single or combination of buttons is used.

2. The Unican 1000 & 7000 series locks CAN be manipulated or "picked" from the outside of the door. Is it easy? No. Is it possible. Yes. In fact, in Alberta they now teach classes on how to do so.

I should also mention that I personally have never allowed the use of the factory combination for any combination locks. With the 7000 series it's not so simple since the customer can change the combo two minutes after I leave, but it's not something I give as an option.

I craked one of these locks in under 10 min. Keep trying u r on the right track. I will let u guys figure it out.

Just a side note, if you have a simplex in bronze with the bronze or black buttons they show wear very well, and you can usually narrow down you combination tries significantly even if the combo has been changed once or twice.
