You manage 500 units. You know the math: one failed smart lock means one angry tenant and one technician visit at $50–$150 per incident. Now imagine this: a tenant reports a dead fingerprint sensor. You send a $15–$45 module. They swap it themselves in under 10 seconds. Problem solved. No visit. No replacement. No complaint.你管理 500 套房子，账算得很清楚：一把智能锁故障，就是一位愤怒的租客，和一次 50–150 美元的师傅上门。现在换个剧本：租客报告指纹头失灵，你寄出一个 15–45 美元的模块，租客自己 10 秒换好。问题解决，没有上门，没有换锁，没有投诉。
That's not just a smart lock. That's a smart business decision.这不只是一把智能锁，更是一个聪明的生意决策。
The original key-swappable smart lock — upgrade with a turn of the key. One lock from family homes to large projects — hotels, short-term and long-term rentals, offices and housing developments. WiFi 2.4G app with remote unlock, fingerprint, password, 50 IC cards and mechanical key — with the patented key-swappable module that keeps service calls off your balance sheet. 原创钥匙换模块智能锁——转动钥匙即可完成升级。从家庭住宅到大型工程全覆盖——酒店、长短租公寓、办公室与住宅楼盘。支持 WiFi 2.4G App（远程开锁）、指纹、密码、50 张 IC 卡与机械钥匙——专利钥匙换模块结构，让售后工单不再吞噬利润。
Accurate and fast: the semiconductor sensor completes identification and unlocks the door in about 1.5 seconds. False acceptance rate below 0.001% and false rejection rate below 1.0% — quick for residents, strict for strangers. 准确而快速：半导体指纹头约 1.5 秒完成识别并开锁。认假率低于 0.001%、拒真率低于 1.0%——对住户够快，对陌生人够严。
Identification识别时间<1.5s
RF-2 connects to 2.4G WiFi out of the box, pairing with the app for full remote management — a guest at the doorstep gets in even when you are miles away. RF-2 标配 2.4G WiFi，连接 App 即可实现完整的远程管理——即使远在异地，门口访客也能即时进门。
After-sales by courier: mail a $15–$45 module instead of booking a $50–$150 technician visit. Your customer swaps it with a key — no tools, no drilling, no downtime.售后就是寄个快递：寄一个 15–45 美元的模块，代替 50–150 美元的师傅上门。客户自己用钥匙换上——无工具、不拆锁、不停用。
A palm-sized module replaces a shelf of spare locks: cheaper to stock, cheaper to ship, and swapped by anyone with a key in under 10 seconds.一个手掌大的模块，代替一整货架的备用整锁：备货更省、运费更省，任何人用钥匙 10 秒就能换上。
Turn the key left 90° to release the front panel — a spare module fixes in under 10 seconds what used to take a technician visit.钥匙左转 90° 释放前面板——过去需要技师上门的问题，如今一块备用模块 10 秒解决。
RF-2 shares the Trueway modular body, so buyers can standardize on one lock and differentiate access with swappable modules — fingerprint for family homes, card-only for hotel floors, keypad codes for rental units. RF-2 共用 Trueway 模块化锁体，采购可统一为一个锁型，再通过可更换模块区分开门方式——家庭用指纹、酒店楼层用刷卡、出租房用密码。
