How key-holding works

Our key-holding services involves us securing your site’s important keys using a high-security storage vault. These keys are then accessed via a valid key that only the key-holding response officer has control of. As soon as an alarm is triggered at your property, one of our key-holding team will attend, checking the premises and carrying out any action if required.

We also provide lock-up and unlock services, escorts of lone staff members in and around the property and, if required, routine internal and external checks of your premises via mobile patrols.

"I would like to say how the services to Nottingham Science Park have improved since being taken over by Crown Security Services. The attention to detail has improved on the reporting and in particular the communication that I receive from the management has greatly improved and therefore the whole process runs much smoothly and professionally. I would be happy to recommend the services."
