Supra
Supra is a well-known key safe / key management brand in the UK trade, most associated with the C500 / C500 Pro style push-button mechanical key safes used for managed access (care providers, trades, landlords, holiday lets, facilities teams) where you need controlled entry without leaving a spare key under the world’s most obvious plant pot.
In the UK, Supra is closely tied to Supra (UK) Ltd, which trades as The Key Safe Company (their distribution arm, active since 1996) and positions itself as a leading UK access-management specialist bringing brands like Supra™ and KeySafe™ to market.
What Supra is known for
-
High-security mechanical key safes (not “smart”, not app-based — just robust, outdoor-rated, code access).
-
Flagship units like the Supra C500 Pro are widely marketed as “police preferred” and sold as high-attack-resistance models with installer-friendly features (capacity for multiple keys, weather covers, clutch/anti-force mechanisms depending on model/retailer).
-
Some listings explicitly reference LPCB LPS 1175 Issue 8 A5 attack testing for the C500 Pro line (that’s “this has been tested by people whose hobby is breaking things”).
Important “don’t-mix-the-brands” note
There’s also Supra Systems in the US market — the electronic lockbox / credential ecosystem used heavily in real estate — which sits under Honeywell after Honeywell completed the acquisition of Carrier’s Global Access Solutions business (which included Supra). Same name, different universe: one is property access lockboxes for agents; the other is the familiar UK wall-mounted key safe world.
