Kaba Puzzle Lock

[Geeves]

I'm new to this forum and I've been manipulating locks for over 15 years now, just as a hobby. The locks I have the most problems with is keyless Kaba puzzle locksets. I have basic opening instructions already but these have not worked. (see http://www.fortliberty.org/military-lib ... ocks.shtml) I spoke to a vendor of this lockset and he says sometimes you need to press 2 buttons at the same time. Has anyone ever dealt (successfully) with this type of lock? Damaging and or destroying the lock is not an option.

I can tell you that these are possble to open, i can't tell you how though

[Geeves]

Just to let you all know I have tried multiple locksets with only a ~20% success rate. I'm having contest at my job between me and the in house locksmith. He says it's not possible at all. I proved him wrong in 5 mins flat! Then he changed the code to a "press more than one button at the same time" ... and... Oh and he has never heard of these locksets being compromised in any way before. (I found this very strange)

[skold]

I'm sure he was just trying to stop you from asking anymore questions than you needed to ask

Or he may have had no idea. I'm starting to realize that many locksmiths are very involved in installing and keying locks, and that the whole picking aspect is terciary. Generally they like to drill, as it means they get to install, (and charge for) a new lock.

They can be defeated with a small hole and repaired with a pop rivit.

Are these the locks which used to be known as Simplex Unican? If so then this is worth a read:

By the way, the new version has an enter button to push once you've input the combo, so the old manip. techniques won't work anymore.

I not sure why there is such a "big secret" about Simplex Locks. I installed about 100 5-button inline units on a US Navy Ship back in 1997. After taking one apart I had figured it out in about 20min. There is about a bazillon places you could stick a feeler pick to bypass them and I had almost figured out how to manipulate them before I came across "The Hobbits" how to guide. I have helped about 8 people recover and change there codes and fixed 2 broken ones at my current job. And just a messed up side note: when I left that ship in 2000 I could still open about 80% of those locks with the default (24)3 code.

This was almost a year old but glad to see your reading the site.

Then if it was you who fitted them you fitted them wrongly, someone fitting these locks should always change the code from the factory set up.

Aside from double-presses, by the way, you can also press buttons halfway.

That said these "extra" options seem to be rare.

I currently am using a Half Press as part of my code for my Simplex on my locker. It is good for confusing "sholder surfers" that may watch me press the buttons. Most of my Co-workers don't even know how to change there combos so I am sure even less realize they can use Half Presses. BTW at least on the locks I have experenced Half Press Buttons will always be used last in the combo because of the way they have to be held down in the change combo process.

[Shrub]

Half presses arent very reliable on worn locks and could cause problems

I know this is a very old thread, but I've seen a friend open a simplex lock in 2 minutes. He was falling down drunk at the time, which is why it took him so long. Apparently, Simplex locks are a joke. I imagine the KABA versions might be a little better, but how much so I couldn't say.
