Sometimes… sometimes it’s simply a case of “spec says work with Ultralight” and they do the bare minimum to meet the spec… sometimes with copied code they don’t understand… sometimes they totally misunderstand how to get the ID and basically do a read command to read the ID from the memory pages instead of the select command, which only works if the tags have the same read pseudo-apdu commands… and the ID is in the same memory location… soooo many ways stupid can play into it.

Yeah but to their credit, the number of different NFC standards, APDU commands and all that jazz is a complete jungle, the documentation is often sketchy, and… well, they’re lock makers, not NFC reader makers.
And yes, to keep costs down, as soon as it works with whatever’s on their product sheet, however poorly, that’s good enough. Not to mention manufacturers that supply “official” tags at obscene prices, that have an interest in making sure their products don’t work with anything else.
Also, for stuff made in China, don’t expect quality.

Hey guys,
I think there’s some misconception about the term ISO. The ISO 14443 and their derivate don’t describe what information from an RFID/NFC tag has to use for any purpose it’s a description about the tag itself. the ISO 14443 for example consists of 4 parts:
- ISO/IEC 14443-1:2018 Part 1: Physical characteristics
- ISO/IEC 14443-2:2016 Part 2: Radio frequency power and signal interface
- ISO/IEC 14443-3:2018 Part 3: Initialization and anti-collision
- ISO/IEC 14443-4:2018 Part 4: Transmission protocol
It does not say much about the content of the data and absolute nothing about what has to be done with the data in any particular case.
It’s up to manufacturer of any product which utilizes this technology, what part of the data is used and how is this part implemented into the product. Of course there will be many different ways of product specialization between the different manufacturers, since the regular consumer is not expected to be knowledgeable enough to discriminate these issues. However, it’s questionable if any specific marketing strategy is preferable or not, this will only shown in the success of any product.
Actually, part 3 should include UID… which is what we’re referring to with ISO14443A and locks

Hey guys,
here is now my update on my new door lock from China. This seller has an Amazon store and offers his products with Amazon Prime, very fast free shipping. The lock came in yesterday and it looks awesome. Here’re the parts that come with it:
The black device is made from metal and very sturdy. The actual keys are special security keys which makes the lock hard to pick. Well, I know if one want to break in they’ll find a way, but hey who ever brakes into my house will just waste their time.
Out of curiosity, I took the lock apart to check on the internals. The PCB’s and the assembly is very good quality.
Here’re some pictures of the main board:
It’s kind of hard to make out what chips are used, but with some effort it probably would be possible. The keypad is made of a flexible PCB and has the NFC antenna incorporated. The keys are capacitive sensors, no mechanical parts. The fingerprint sensor is a module and can be easily replaced in case it gets damaged.
The lock comes with a very good set of instructions for installation and operating. The lock also works with a App for Android or iPhone. I’m not an iPhone person and didn’t test the App for that. The Android App is very intuitive and works great with all settings for the lock accessible from the App.
Here’re some video’s from the lock working:
LAXRE door lock closing - YouTube
LAXRE door lock opening. - YouTube
Pros:
- sturdy metal housing
- good quality parts and assembly
- works with Bluetooth
- Fingerprint
- NExT NFC implant is working other NTAG216 from NXP tested too
- nice phone App
- easy install
Cons:
- uses 4 AAA batteries, could be 4 AA batteries
- motor makes a week impression, but I can be wrong

Great write up, thanks for that 
People on here are always looking for Door lock options.
Especially ones that can just “drop in”. ie no need to make new holes?
Do you think that is possible?
For those playing along at home, here is the link
AMAZON store: Laxre Bluetooth keyless Fingerprint Door Lock
You are looking at around the $100 mark
with colour and form factor options.
I will update the matrix when you have done some implant testing.
So we know what “off the shelf” implants will work, Could you do a TagInfo scan of the fobs for us?
And hide your ID, we just want to see the rest of the Info.
but worse case scenario, the fobs look very possible for Amals conversion service
but worse case scenario, the fobs look very possible for Amals conversion service
Overall, It looks like a decent bit of kit, for the money
EXCEPT
Nope 
For what it’s worth,the more opening options they put on a lock, the more options there are to…Bypass it!
I used my NExT implant to open the lock which you can see in this video:
It’s very simple to program the lock for particular NFC chips, just use the Phone-App for the lock and that’s it.
Here is the App for android:
The lock comes with two NFC cards which I’ll scan as soon as I’m back home, where you wnat me to send the results?
You have to understand, for me is lock-picking similar to magic and now those keys having a grove in the center which probably makes things even more magical.
You’re right with your argument about the many options which opens more possibilities to bypass the lock. As already mentioned trying to brake into my house is just a waste of time and on the other hand, who in their right mind would like to spend the last minutes before getting shot with figuring out how to open a door lock from China?
Immediately checks for ch751 
But seriously, you’re missing a huge potential security flaw of devices like this of being “keyed alike”
Sooooo many security products use THE SAME lock core and only have a single key, because it drastically simplifies getting parts for production
Even IF it’s a hard lock to pick, how certain are you if I buy one I won’t get the same key? ( this is a valid attack strategy sometimes )
Noted
I’ll wait for this before I do the Matrix, it will give us a better idea of what implants will be compatible.
If you are happy to share the results here, or if you prefer you can DM me.
I forgot, you guys are in always in and out of Lockdown.
So I guess you are more often than not at home, and I’m guessing cleaning your guns, practicing your quick draw

Nice one,
looks to me, to be a Mifare Classic 1k 4 Byte NUID.
It worked with your NExT, so my guess is it should work with ANY of the HF ISO14443A implants.
I’ll put it up on the Matrix today
Bad guess. If I’ve said it once … etc… testing is the only way to confirm. DESFire? Spark 2? These may not work.

Yeah, as usual you are right…sorry 
I should have Highlighted and EMPHASISED My guess
I was only going to put the NExT and variations thereof plus the Mifare “Magic” implants as green onto the matrix until the others can be confirmed…

Holy height over bore Batman! Lol
Make sure you teach mechanical offset and holds
I have added the Ubiquiti Access control to the Matrix, and added the NExT and it’s varients, plus Mifare “Magic” 1k until we can confirm some more implants
Thanks
I implanted my Spark 2 the other day and it works on the door lock like a charm, even with the hand still swollen.
@Pilgrimsmaster You can now add the Spark 2 as green for this lock if you wish.

Cool, thanks for the update, I will do

While you make valid points, I doubt a typical B&E criminal is going to waste time and brain cycles when the alternate Basic Opening Operational Technique that most less-than-savvy people employ works extremely well against non-hardened installations.
Ideally there are multiple levels of security, bypassing a lock shouldn’t be a point of total failure.
Hahaha you’re right, ditching those 44’s once you inside the house is much more difficult.
