Audit-ready and complete: smart key management for security and guarding services

Picture the situation: at two in the morning a burglar alarm comes in at the alarm receiving centre. The patrol vehicle arrives at the site, but when the officer reaches for the key ring, the main key is missing. The search begins while precious time ticks away.

Sound familiar? For guarding and security services, clients’ keys are at the heart of everyday work. Unclear handovers at shift change, illegible paper books and missing evidence for clients are a considerable security and liability risk.

In this article we walk through the most common pitfalls in key management at guarding services — and how to get them under control effortlessly and with a proper audit trail using Log+Key.

4 familiar key situations in guarding services — and how Log+Key helps

1. Shift change at 10 pm and the handover book has gaps 🔎

  • The problem: When patrol vehicles and key boxes are handed over, there is no time for long paper entries in the rush of the shift change. Gaps appear and responsibilities blur.
  • The Log+Key solution: Lightning-fast digital sign-off. With a PIN or NFC tag at the terminal or on a smartphone, every key handover at shift change is signed off verifiably in a few seconds.
At the terminal: tap your name, enter your PIN

Screencast: at the terminal Max Muster is searched for and tapped, the “Enter PIN” dialog appears; after the PIN the terminal shows the overview

2. An alarm at 2 am — and the client’s key has to be found first 🚨

  • The problem: A response officer is looking for the right key on the way to the site because it isn’t where it should be in the vehicle depot.
  • The Log+Key solution: Transparency about exactly where it is. Log+Key shows straight away on the smartphone which vehicle or safe the key is in and who last took it.
Open a location — with counters for the stock

Screencast: list of locations, detail page “Leitstelle Musterstadt” with the counters objects, in use, available and archived

3. The client asks where the master key is 🔑

  • The problem: After several years of contract, a client asks for detailed evidence of where their master and duplicate keys have been and how they have been used over the years.
  • The Log+Key solution: A complete history at the push of a button. With the history feature you produce a complete record of every checkout and return for any period in seconds — as a CSV export for your client.
Filter the history and open an entry

Screencast: history with the filter, then a history entry with the “Print receipt” and “Send receipt” buttons

4. The audit is coming up and the key records are a mess of paper 📑

  • The problem: A certification audit (for example to DIN 77200) is coming up. The auditors want proof of complete, tamper-proof key management.
  • The Log+Key solution: Audit-proof cloud documentation. Log+Key stores every movement in a tamper-proof way — history entries are never deleted. So you go into the audit without days of preparation.
