The lock and unlock service

Your most vulnerable times aren’t during the day.
Early morning openings.

A quick view of the types of sites where a consistent on-site security presence is most valuable.

Lock & Unlock Services for Commercial Premises in Yorkshire & Lincolnshire
SPS Security provides scheduled lock and unlock services for commercial premises across Yorkshire and Lincolnshire, ensuring your site is opened and secured by a trained, SIA-licensed officer every day. This service is ideal for businesses that want to remove the burden of key-holding responsibilities from staff, or that need a reliable and professional opening and closing routine.
A safer, more professional alternative to staff lock-up
Asking staff to open or lock up a commercial premises alone — particularly early in the morning or late at night — creates significant lone worker risk and personal security exposure. If an intruder is on site, or if a problem is discovered during the routine, a member of staff attending alone is in a vulnerable position. By transferring your lock and unlock routine to SPS Security, you eliminate that risk entirely and ensure every visit is carried out by a trained security professional.
Our officers will open your premises at an agreed time each morning, carry out a basic security check, and lock up securely at close of business. Every visit is documented and any issues found during the lock or unlock — from unsecured access points to signs of damage — are reported immediately and escalated through our 24/7 control room.
Full audit trail and compliance documentation
Full audit records are maintained for every visit, providing a clear and verifiable trail of who attended, when they attended, what was checked and what was found. This level of documentation is increasingly important for businesses with insurance or compliance requirements, particularly in sectors such as education, retail and healthcare where accountability for site security is closely scrutinised.
Our lock and unlock service is fully integrated with our keyholding and alarm response service, creating a seamless out-of-hours security arrangement. If an alarm is triggered after lock-up, the same keyholder relationship means our officers can respond immediately without delay.
Consistent, reliable cover seven days a week
SPS Security provides lock and unlock cover seven days a week, 365 days a year, across Yorkshire and Lincolnshire including Hull, Leeds, Sheffield, Doncaster, Grimsby, York and surrounding areas. We handle all holiday and absence cover internally, so your opening and closing routine is never dependent on a single individual. All officers are SIA-licensed, vetted and trained to the same professional standard.
Lock and unlock duties are often specified as part of wider reactive security works contracts, alongside keyholding and alarm response. SPS can deliver these as a standalone arrangement or as part of a joined-up out-of-hours security model.

Wider managed coverage where required
SPS directly delivers mobile patrols, keyholding and alarm response across our core Hull, East Yorkshire, Grimsby, North East Lincolnshire and wider Yorkshire & Lincolnshire operating areas.
Where clients have sites beyond our direct mobile patrol footprint, SPS can support wider coverage through selected SIA-approved partner providers. SPS remains responsible for managing the service model, reporting expectations, escalation process and client relationship, helping multi-site clients maintain a consistent standard even where local response is delivered through an approved partner.
Additional support and technical integration
Lock and unlock services can work as a standalone arrangement, but they also connect well with keyholding, alarm response, mobile patrols and wider technical support. Where clients need a more joined-up model, SPS can align opening and closing routines with monitoring, response and electronic security systems without overcomplicating the service.
This means clients can speak to SPS about the full security picture, whether they need a standalone service or a more joined-up solution across people, systems, monitoring and response.
SPS Security and SPS Technical work together as part of the wider SPS Group. This allows clients to access physical security, monitoring, response and technical security systems through one joined-up regional provider.
Practical client-level support on SPS Security
SPS Security can still support enquiries for CCTV, alarms, access control, monitoring, keyholding, patrols, guarding and combined solutions directly, while SPS Technical provides deeper technical detail and project delivery support.
