keyless combo lock for doors

[kodierer]

The people who sell this lock say that it is not electric, that it is completely mechanical. The site doesn't seem to give info on how it works, and I was curios as to if anyone knew(how it works that is).

[acl]

Cheapo mechanical digital door lock.Numbers 1-0 letter xyz and c.
To enter press c to clear any other numbers .then simply put in your number and turn the knob and youre in.
The downside to these is that you can put in any variation of your code and still get in. Can also be a bit of a pain to change the codes if youve not done them before,theres a lot of springs in there!
Maybe someone could put up a more detailed explanation with some pics at some point(if its not been done before)
As i said these are very cheap we can pick them up for around £20 over here.

Based on An Ilico Simplex Lock:

They are quite a mess on the inside. They have 3 rotating spindles. One with 5 round wheels on it,which all have one notch. Every time a button is pressed ALL of the wheels are moved. You can only press 5 buttons too because theyr is a triangle shaped piece of metal, which as every button is pressed it scoots over a bit more. Then it just cant go anywhere.
This is when you have to restart. Once the correct combo is entered you turn a knob. This lowwers a piece of metal with tabs sticking out into the gaits of the wheels.

Hello all,

To change the combo on this type of lock you need to undo it from the door and look on the back of the lock.

You will find a series of metal bits poking out of the mechinisims which you can remove or insert either way up.

Depending on which way up the tabs are depends on what the code is.

They are a very cheap and nasty lock that are not very secure if you know the by pass methods.

I hope this helps, Jim.

Andy is this ok ?


The PushButton code chamber consists of 13 buttons from which the code is selected, and a 'C' button which is used to re-set the chamber after an incorrect entry, and which must always be used as the first digit of a code. Buttons may only be used ONCE in a code. For example, 1212 is not possible. A PushButton code, or combination, can be entered in any order or sequence; e.g 1234 can be 4321 or 1342 or whatever sequence is most convenient to remember.

With 13 buttons, a total of 8,191 different codes are available, any of which can be entered in any sequence.The total is arrived at as follows:

'C' plus 1 digit = 13 'C' plus 6 digits = 1716 'C'plus 11 digits = 78
" 2 = 78 " 7 = 1716 " 12 = 13
" 3 = 286 " 8 = 1287 " 13 = 1
" 4 = 715 " 9 = 715
" 5 = 1287 " 10 = 286
Total = 8191

Most people will set a code in the range of 4 to 7 digits, and the total number of codes in this range is 5434. The lock is factory set with a randomly selected 6 digit code starting with the C button. The code is not recorded by the factory. The code can be changed as often as required to any other 6 digit code. Every new code must start with the C button. Using the spare tumblers, one red and one blue, the code length can be changed to 5 or 7 digits. Shorter codes are not recommended.


--------------------------------------------------------------------------------

Code Change Instructions

Take your PushButton combination door lock off the door by unscrewing the 2 screws in the backplate.
Press the C button to reset the chamber and place the lock case on a flat surface with the buttons down.
Remove the 2 red screws and carefully lift off the code chamber plate. Check that all 14 springs are held in place on the plate.
Note that the 5 red tipped code tumblers correspond in position to the existing code. The 8 blue tipped non-code tumblers fill the other positions. The C tumbler is not coloured.
Hold the lock in your hand and depress the C button. Keeping the C button depressed use tweezers to re-position the tumblers to correspond with your new code. DO NOT force the tumblers in.

NB: Holding the C button depressed whilst re-positioning the tumblers is ESSENTIAL to avoid damaging the internal mechanism. DO NOT attempt to reposition the C tumbler. The square notches of all the tumblers MUST face outwards with the coloured tips ON TOP.

some pushbutton locks seem to allow for a push two buttons simultaneously and the push halfway in option, I have encounterd both of these in the past. there are 5 6 or 10 button types, none of them can be considered security, the code can be seen being entered, a video camera from a distance with the proper telephoto lense will pick it up. A bit of lipstick or invisible uv powder applied to the users hand by another door knob will 'tell' the buttons used just as long wear will dirty up the buttons, but a marker like lipstick meant to transfer will transfer most heavily on the first number, and least on the last number as it get used up and in this way it tells not only the numbers but also the sequence. These types of locks are best for semi public restrooms where the combination is changed from time to time, like the one at my bank, Such locks are not secure, there is a way to feel them out, this also applies to the ten number key locker box. (similiar to the keyboxes used by realtors.)

Looks like that is a "Lockey" pushbutton lock. One feature I like about them, is that a pipe wrench can't be used for brute force entry. The knob does nothing until the correct code is entered.
Just like any other lock on the market, There are ways to bypass it.
Let's just get it out in the open, and say ALL locks suck because one way, or another, they can be compromised.

Would anyone like to see the innards of this lock?

argh no edit button, brain and hands dont move at same speed

would anyone benifiet from seeing the innards of a simplex?

The versions of these that can have 2 buttons pushed at the same time in the codes cost a fair bit more. These can cost up to £300 retail over here for the good ones but as mentioned before can be bought a lot cheaper. Im fitting some of these in a couple of weeks for a church. They are a great way of securing a door in high use areas where you just need to keep chancers out and dont want the expense of cutting loads of keys and then changing the locks if one falls into the wrong hands.

Hello all,

If i remember correctly Scotland Yard had those locks fitted to all of their doors a while ago, and after a short time had them all replaced again.

[Buggs41]

If they wish to sell some, I am interested.

My security requirements are lower than theirs.

I personally like how Simplex locks (allow multiple button pushes, require a specific order, and allow half pushes) are used for "secure" areas. Especialily when they don't install a core in the key bypass.......

[acl]

The model shown isnt the ilco simplex they work differently it is as someone said a lockey or borg ,aldridge and euro also do there own and probably ahost of others.
Ilco do a few different ranges,7000 series,3000,2000 and 1000.
Id do a proper write up myself but i cant suss out how to get pics up so maybe someone else could do one including bypass techniques etc(lazy tosser i hear you cry)
