13.56MHZ MIFARE Classic 1K Key Fob RFID Access Tag Black Metal (5)

Work perfectly and holding up great after months on multiple keychains.

I specifically bought these for the Aqara Smartlock u100, based on others mentioning these worked with their smart locks. I can confirm these do in fact work quite well.You can bind 2 of these per user, and if you have multiple smart locks like I do, you can bind the same tag(s) to each smart lock if you want. Or if you want to have one tag give access to one door and not the other, you can do that as well.

Perfect replacement for the cheapo keychain fob that came with my door lock. Solid construction so hopefully doesn't break like the crappy ones on a string.

These are made sturdy unlike the flimsy ones included in the keyless entry door device I purchased from another company. The key fob attachment has real metal and the fob is a sturdy material and extremely responsive. It paired with my system without any problems. Plus, 5 fobs included. I paid at the time less than $13.

I was able to connect these to our Veise smart locks, and they work great with them. Much better looking than the stock ones that came with the lock, with a much more robust attachment point to your keys.

They worked as they were supposed to.

Seamless setup with Aqara Smart Lock U100 door lock.

These are compatible with the great Aqara U100 smart lock. And much more economical than the brand name Aqara NFC tags. Fire up the Aqara app, set it into NFC connection mode, and touch it to the lock. Presto, it is coded in 1 second flat.
