Keyless entry quickly died and not reparable The fingerprint opening worked fine until the battery got charged for the second time, after it died (that’s about 1 year of use) Now it’s just a heavy key lock, with a rotting battery inside. Neither good for the planet or your wallet, better stick to a quality lighter key lock from trustable brands

It’s fine I guess Well, for starters it took a long time to get to me. They say they have warehouses in the US and Europe, but apparently they’re having trouble keeping those stocked so mine was shipped all the way from Hangzhou, China. It took about two weeks—twice as long as their original estimate. On to the lock itself. It feels hefty and substantial; The folding arm is fairly thick metal. However, the casing that holds the electronics is plastic. It would probably stand up to some abuse, but it wouldn’t even slow an angle grinder. The joint where the folding arm meets the casing is also just a little loose in my unit—it does feel like if I put too much pressure on it in the wrong way it might break at that joint. It also has a backup physical keyway that opens the lock if the electronics fail or the battery dies. This is a neat feature but that keyway appears pretty insecure. The gold standard for bike lock cores is Kryptonite’s Disk Detainer core which appears in many bike locks and has a very distinctive key shape; this is not that. It looks more like the sort of lock that goes in car doors; pretty trivial to pick if I remember correctly. The electronics themselves work pretty well. The pairing process is pretty straightforward and the app works fine. The fingerprint reader sometimes takes a couple tries but I really appreciate the convenience of not having to carry around another key. There’s also some Bluetooth functionality which I turned off to save battery; it’s not useful to me. There’s an anti-theft alarm, which is nice in theory but it’s way too sensitive by default and it only works within Bluetooth range anyway—so what’s the point? Other reviewers claim it doesn’t stand up to water. It doesn’t rain much where I am, so I can’t verify this, but the lock body doesn’t appear to be watertight and there is some air space inside. Unless they’ve coated the board with conformal coating then the other reviewers are probably right—it’s unlikely to hold up in the rain. Their support was responsive enough for me. I ordered the bike mounting sleeve (pro tip, you don’t need it—it already comes with one.) I contacted them for a refund and we worked something out. Refunds could be difficult though, because they’ll want you to ship your unit back to China, which can get very expensive. In short: it’s fine I guess. I’ll keep using it.

Battery with short life I made a very similar experience to what is described in the previous reviews: I bought 4 Locks 3 years ago and all of them are dead now and can’t be charged anymore. „Support“ says its a battery issue but they are not willing to replace at least 2 of them after the warranty period referring to „company policy“.

Do not buy Ziilock they will brake and have no service Do not buy Ziilock. i bought two of them. it took a long time before they arrived they where delayed. i used one of them for a summer. it has been charged once. the second time i charged it i put it back on my bike and when i needed it it was empty again so i thought. I took it inside from the shed again to charge but no light was coming on it was dead as a doornail. contacted Ziilock and they ask me to take a video from the brick zo i did. after a few months without reply i tried it again. they asked me to sand them some more info. They replied and told me it was the battery that died and it was out of 1 year warrenty. so do not expect it be used a lot it is crap and the company has bad customer service and they take ages to reply.

Device was broken some weeks after use Device was broken some weeks after use, support not helpfull, quality is very bad sadly, had to use the key after couple of weeks, and even the key broke almost...
