Ironically, master lock do not suggest using these in their key boxes yet obviously there are cases where they are required. Be prepared they do take up a little room so placing the key back in can be a bit tricky. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/332129885-master-lock-5490eurd-retractable-tether-for-key-safe-up-to](https://www.desertcart.co.th/products/332129885-master-lock-5490eurd-retractable-tether-for-key-safe-up-to) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-07-18*
