Rank #8 in Best Key Safe 2026: 10 Ranked, and the Numbers That Don't Add Up
Rhino Lock Secure Key Combination Safe, Medium, Black
Price and rating as shown on Amazon when we collected them. Both change.
The Rhino Lock Secure Key is the key safe at number 8 in this guide. It costs £25.95, which is less than half the £68.95 of the most expensive box in the list, and it carries 4.6 out of 5 from 836 ratings — the largest review base of any product here. Its own bullet points promise a heavy duty aluminium alloy body, a 4 digit combination lock, a wall mounting kit in the box and roughly 167 cm³ of internal space.
The number worth checking is that 167 cm³. The same listing's spec table measures the case at 4 cm deep, 9.5 cm wide and 11.5 cm high, which is 437 cm³ of exterior volume before you allow for the thickness of the walls, the door and the lock mechanism. The spec table also lists a 'chamber depth' of 11.5 cm — the same figure it gives for the height, which cannot be an internal depth in a case only 4 cm front to back. Everything on this page comes from the Amazon listing and its customer reviews, not from any test of our own.
