there was a talk about 'smart' locks at 33c3
jump to ~43:00 for the master lock
Maybe the cam was magnetically susceptible. I can see how the rolling motion might cause it to rotate.
If so, then all they needed to do was change that material to something non magnetic.
If the magnet was interacting with the armature of the motor, then changing the casing to something like mu metal might do the trick.
Btw, since you seem to have a passion for locks, you should consider a teardown of one of the safest commercial door locks in the world, the Simons Voss digital cylinder system. Even big companies like Siemens use it.
Meh, this one has never been picked:Probably not enough incentive to..
Are the backup battery pins in parallel to the normal battery? This would be bad, because when the battery inside is discharged (maybe by a paper clip from someone else who don't like you), an external battery might not help anymore and the internal battery can't be removed.Yeah, an external battery might not help but you can still bring a low impedance power supply to the rescue.
Also maybe very easy to brick, by applying some high voltage at the backup pins (electric lighter).

Why do they have both a CC2541 and a MSP430?
Youtuber bosnianbill has made numerous videos lockpicking Masterlock brand padlocks, and from these videos, it appears that this brand's products are subpar.
Here is his Masterlock playlist for those of you who would like to judge by themselves:https://www.youtube.com/playlist?list=PLTSWkYxuSlkVyTvKncLO54dKuoLCaQXsD (https://www.youtube.com/playlist?list=PLTSWkYxuSlkVyTvKncLO54dKuoLCaQXsD)

and the third has been reduced to an inconvenience (contacts for external backup batteryAn inconvenience that only this lock has.
Why don't they just use microUSB as power backup. The chances of having a USB power bank + microUSB cabe are a million times higher than someone carrying around a spare CR2032. It's just stupid :palm:
An internal battery that eventually wears out, making the lock pretty much useless for its original function? |O :palm: The concept might not be too smart but at least they decided having a replaceable battery would be a good idea...Why don't they just use microUSB as power backup.

The whole thing would be better with an internal rechargeable battery. No need to go looking for an expensive coin cell every couple of weeks (or however long it lasts).
How long does the battery last, BTW?

I think we are in violoent agreement that the whole "smart" concept does not make much sense for a padlock.
Q: How long will the 4400 series battery last?
A: The 4400 series battery should last at least 2 years in Touch Unlock Mode and 4 months in Swipe Unlock Mode with regular use.
Q: How long will the 4401 series battery last?
A: The 4401 series battery should last 5 years in Touch Unlock Mode and 2 years in Swipe Unlock Mode with regular use.

I'll bet that the probabilities are the other way around.
I will bet that a minimum of 90-95% of forum members will have a handy CR2032 on their person when they are out and about. It'll be on their key chain, on a car remote locking/alarm fob. I will also bet that less than 5% of them have a handy USB power source and cable about their persons under similar circumstances.
Whether the average person has the presence of mind to realise that they are already carrying around a CR2032 is another matter; after all, you didn't realise it.
Some of these products ... lack any functionality that rationalizes their existence. I think a BT lock would make sense if it added the kind of features that ... you can already do with a regular lock.
- only allow open if a supervisor's phone is nearby (something you know and something you have)
- allow a one time open (e.g. give a one-time-password to a service person who needs access)
- retractable codes (so certain users can be removed from the lock)
- logging (who opened the lock and when)
- two person (split keys)
- hierarchical keys (supervisor followed by employee)
- master open (e.g company owner)
I hate this whole trend with so many products that it requires to make an account though, this is completely ridiculous especially for an offline device.

It would be remarkable if there is a registration process yet no collection even of basic things e.g. name, phone number or e-mail address, and so on.)
If you already carry a CR2032 on your keychain ( mine can only be extracted with a small TORX driver), then why not just add a key for a mechanical lock.

This entire concept simply makes no sense.
These responses are mean.
These responses are mean.
The pin and tumbler lock dates back to Nineveh (at least) which is 4000 years ago. It is even older than red LEDs.
Isn't it time that it is improved upon?
These responses are mean.
They are indeed. Frankly, I'd say more along the lines of this is getting utterly ridiculous, and not a small amount down right irritating — I'm following this thread to see if any useful comments or product comparisons turn up, and wading through the sea of crud is not particularly enjoyable. Though it probably wasn't helped any by Dave's own response to the device — the sheeple always come out, in the shadow of their shepherd. Anyhow…
...
I'm fairly certain this padlock is still better than the ones I use (and have used) in any of those situations, and the convenience it offers doubly so; I'd much rather something like this on my gate than having to fumble with a key while it's pouring rain on a winters night (my current gate padlock is a $10 Coles jobbey, since anyone wanting to bypass it can — and all too often do — simply jump the fence anyhow.
And while the digital security of many of these locks pains me even more than their physical security, I myself will still be keeping an ear open for further reviews of flaws (and fixes) regarding these bluetooth enabled padlocks

I wonder if it's firmware updatable.
It's not hard to imagine there's a software bug lurking... maybe even a sniffer that lets you walk near the owner and pretend to be the lock so you can grab the code. If you see somebody put a bag in a locker and close it with one of these things there's a good chance there's a Macbook or iPad inside.
a) The shepherd couldn't actually open this with his phone.
b) If it's raining then that's all the more reason to get something reliable (eg. doesn't depend on battery charge).
c) It's better to spend $10 than $100 if people are likely to break it.
Nope, this is aimed squarely at the locker-room-frequenting-hipster demographic. People who want other people to notice their shiny padlock.
Nobody serious about securing anything is using anything from Master, that's for sure.
So, it falls into the "if you're really not securing anything and you want a gadget, go for it" category.
So... a Bluetooth lock is overkill at this quality level. It'll sell great to the gadget crowd. But it won't really secure anything.
BT locks are new. Early adopter products usually suck and are always somewhat silly. Routinely overpromise and under deliver. This one is no different. BT locks are gadgets. For now. BT locks are for early adopters - for now. But I can think of many reasons a BT lock would makes sense - needs for which a regular lock is either too limiting and cumbersome - or a purpose built lock - too expensive. (BTW - Electronic locks are not new - they have all but displaced the most security minded safes. Just look at what the Mas Hamilton x-09 and X-10 did to GES requirements. They are that good. They cost as much as well.)
We've seen from the recent debacle with the bricking of Lockstate locks by a remote firmware upgrade, that remote updating for electronic locks must be regarded as a vulnerability. At the same time, any experience with software security at all tells us that one must have the ability to update firmware/software to cover the inevitable vulnerabilities that will be found.
