Linkstyle MATRIX II Smart Key Lock Box Review — Is It Worth It? [2026]

Linkstyle MATRIX II Smart Key Lock Box
A zinc-alloy key safe you can open with a fingerprint, PIN, keycard, the app or an old-fashioned key.
Is the MATRIX II worth buying?
If you hand keys to guests, cleaners or contractors, yes, it is a useful upgrade over a basic combination lockbox. Five ways in (fingerprint, PIN, IC card, app, manual key) and an IP65 rating cover most real situations. The catch is remote access: out of the box it is Bluetooth with roughly a meter of range, and real remote control needs the separate wireless hub, which is why the bundle option exists.
A lockbox with a few too many ways in, in a good way
The MATRIX II is the upgraded version of Linkstyle's earlier key box. It adds a protective hood over the keypad, a more durable build and a manual key as a last resort. You can buy the box alone ($99.99) or bundled with the Wi-Fi hub ($109.99).
What stands out on the MATRIX II
Fingerprint, PIN, card, app or key
Fingerprint, passcode, smart IC card, app and a manual emergency key are all supported. Passcodes can be set for single use or longer stays, which suits short-term rental turnover.
Zinc alloy and a weather hood
The body is aluminum and zinc alloy with tempered glass, and the listing says it survives drops from about a meter. A hood covers the keypad, and the IP65 rating means rain is not a problem outdoors.
AAA batteries, USB-C rescue
It runs on 4 AAA batteries, rated for about 7,000 unlocks (10 to 12 months of normal use). If they die, a USB-C port gives it temporary power so you are not locked out.
Hang it or screw it down
Use the included shackle to hang it on a door handle or car door, or mount it to a wall or gate with the supplied screws. It also works as a portable safe in hotels.

A solid smart key box with one catch
The hardware is genuinely good for the price: tough, weatherproof and flexible. If you want to give out access remotely, budget for the hub. This is an editorial score by the Teelacodes team, not a customer rating.
