Wireless Access Control System with Door Exit Button Controller Remote Control DC 12V for Entrance Keyless Entry Door Lock for Home Offirce Apartment

The media could not be loaded. Parts were missing (diodes, screws) which wasn't a major issue. I specifically bought this as it advertised rolling codes. My RF analysis and testing showed this is a fixed code device and is vulnerable to standard replay attacks. Even a Flipper can exploit it.I tried repairing remotes as well but to no avail. The device is simply not using rolling codes through either remote.If you're happy with this, it's a reasonably priced device for the purpose, but not for me and it's not as advertised. The manual also says it uses rolling codes. It demonstrably does not.Note the frequency is 315MHz AM and the protocol is identified as Princeton 24bit by a Flipper Zero. I tested this with raw as well to prove it wasn't doing anything in the background but only allowed to upload one video - photos attached.
