Every house has one door that is a nuisance — the bedroom, the office, the roof stairs — where a key exists but nobody knows where it is. The Lockin Q1 replaces that door’s knob with one that opens to your thumb, and it fits in the hole the old knob came out of.
Three ways in, none of them a key
Fingerprint for everyday use, a PIN code for guests, and the app when you are not standing at the door. Prints are recognised in well under a second, so it is faster than the key it replaces, not slower.
You can see who opened it, and when
The app keeps an access log, so you know what time the kids got home or whether the office door was opened over the weekend. You can add and remove fingerprints and codes without touching the hardware — a domestic helper’s access can be revoked from your phone.
It fits a standard door, with a screwdriver
No wiring, no electrician, no drilling a new hole. It mounts to a standard interior door in place of the existing knob, in roughly the time it takes to change a handle.
Battery life measured in months
It runs for months on its cells and warns you well before they run out, so the failure mode is a notification rather than being shut out.
- Fingerprint, PIN code or app unlocking
- Sub-second fingerprint recognition
- App access logs — see who opened the door and when
- Add or revoke users remotely
- DIY installation on a standard door — no wiring
- Months of battery life with low-battery alerts
- Clean, minimal finish for home or office
This is the exact knob filmed for the review above, inspected before listing — which is why it is half the price of a new one. Fit it to the door you keep losing the key to and be done with it.
