Pushbutton door locks?

Hi, I have a pick set and got pretty good at simple locks like filing
cabinets and desks and even combination padlocks. So next I want to look
at how pushbutton door locks work. The type where you enter C1245 and it
opens.
Any ideas where to start? Google isn't helping :)
tnx, Nik

There are lots of "pushbutton" door locks. Are you talking electronic or mechanical? If you are interested in simplex/unican type mechanicals then here:

Well I did that with our 4 combination safe but it didn't help!! I could watch the mechanism working as I turned left or right, but it didn't help. I found a tech note on graphing which helped more.
Anyway, I have one on the office door. I can always take that off one day when it's quiet... :)
tnx, Nik

On the subject of mechanical digital locks has anyone noticed that in the most basic ones if the code is for instance C1234Y, any permutation of the four digits will will work, ie C4321Y, C3214Y etc.

Yes, I had. And I was sat in the bath the other night just wondering how long it would take to try all combinations and I reckon not that long. 0123 0124 0125 0126 0127 0128 0129 0134 0135 etc as you can't have the same number twice and they can be entered in any order. Half an hour?? :)

Except that the usual C1234 types also have XYZ which have the same status as numerals. Also, while 4 digits is the norm, the locks also come with a couple of extra tumblers and change tweezers, so if you are paranoid, you could use the likes of C123XYZ.
To confuse things still further, the special 'reset' tumbler usually at C can be put in any position, although, granted, it would be easy to determine this.
Suffice to say they provide adequate security for their purpose, and are probably no worse than a Kwikset keyed lock.

With these locks clean the buttons with metho to get the fingerprints off then a week later check the buttons for fingerprints, if the C has not been moved this will give the code.

Holy shit somebody on here will actually post something about locks. I already knew pretty much everything in there but still I'm freakin shocked. Better watch out or Keygirl will "plonk" you and shreek "troll" "troll" before running away and hiding under his damn bed.

TEACH lockpicking? You can't even LEARN to read. He didn't ask a goddamn thing about lockpicking.

Lockwood (Austraila) have a lock that only the C (clear) has to be pressed first the other buttons the order does not matter these locks can use 4-6 numbers depending on the setup.

You know, stood at the urinal yesterday, I came up with the very same idea - and *before* reading your post - honest! I'm going to try it on our own office door tomorrow if I remember to take the black light in :)
tnx,
Nik
