Imperial Security provides a 24/7 key holding service for businesses and residents in Harlesden, acting as primary or backup keyholder for shops on the High Street, industrial units near Park Royal and homes around Roundwood Park. Our SIA-licensed guards respond to alarm activations, unlock and secure premises to a set schedule and give emergency services fast access when something goes wrong.
If you need someone reliable to hold a spare set of keys and turn out at any hour, this page sets out exactly what that cover includes.
Harlesden sits between two very different types of premises: a dense, independent-trader high street around Craven Park Road and Church Road, and the industrial estates of Park Royal a short drive to the south. Both share the same weakness out of hours. Shopkeepers and warehouse managers who live some distance away cannot always drop everything when an alarm goes off at 2am, and a delayed response leaves a door or shutter open to the street for longer than it should be.
A local key holding service closes that gap. Instead of a director or shop owner driving across London at short notice, a trained guard who already knows the area attends, assesses the situation and secures the property. It also means alarm activations get a proper response every time, rather than being reset remotely without anyone actually checking the building.

| What Our Harlesden Key Holding Service Provides
Whether you run a shop unit on the High Street or a warehouse near Park Royal, the six duties below cover the situations that come up most in Harlesden.
Alarm response
We respond to alarm activations at any hour, attend the site, check the building and send you a written incident report once it is secure.
Secure key management
Keys are held off-site and logged under strict access protocols, so only authorised guards can retrieve a set for your building.
Emergency site access
When the fire brigade, police or a contractor needs to get in, we meet them on site and open up without you needing to travel back to Harlesden.
Lock and unlock services
We open and close your premises to a set timetable, so opening hours no longer depend on which member of staff can get there first.
Property patrols
On every attendance our guard checks the perimeter and interior, confirming doors, windows and shutters are secure before leaving.
Incident management
If a break-in or other emergency has occurred, we liaise with police and your insurer and stay on site until the property is fully secured.
| Who We Provide Key Holding For In Harlesden
Our Harlesden key holding clients tend to fall into four groups.
Independent shops and takeaways
High Street and Craven Park Road traders who need someone to respond to an alarm without leaving home in the middle of the night.
Warehouse and industrial units
Operators near Park Royal who need a keyholder able to reach a large site quickly and check loading bays as well as the main entrance.
Residential blocks near Roundwood Park
Landlords and managing agents who want a backup keyholder for communal doors and plant rooms when caretakers are off duty.
Schools and community buildings
Sites that need a dependable out-of-hours contact for alarm callouts and access for caretaking or maintenance staff.
We also support offices and small commercial units elsewhere in Harlesden that need the same standard of out-of-hours cover.
| The Security Problems We Solve In Harlesden
Harlesden's mix of a busy independent high street and nearby industrial estates creates a specific set of out-of-hours problems, most of which come down to nobody being available to attend a site when something triggers an alert.
Owners living outside the area
Many High Street businesses are run by owners who do not live locally, so a late alarm activation can mean a long drive back. A local keyholder attends in minutes instead, using our own knowledge of the surrounding streets.
Large industrial units with multiple access points
Warehouses near Park Royal often have several doors, roller shutters and a yard gate, which makes an alarm activation harder to assess remotely. We physically check every point of entry before confirming the building is secure.
False alarms left unchecked
Faulty sensors and system glitches are common, but resetting an alarm without attending risks missing a genuine break-in. Our guards attend every activation and confirm the cause before the site is left unattended again.
Contractors and deliveries outside trading hours
Maintenance work and early deliveries often fall outside staffed hours. We hold keys to let approved contractors in and lock up again once the work is finished, without a manager needing to be present.
