Open and Lock

What is it?

Locks and Unlocks – Also known as Open and Lock Services ARK takes on the responsibility for alarming and securing your premises at the end of the working day and ensuring that it’s safe to enter at the beginning of the next working day.

Our SIA licensed security officers are responsible for locking up at night after workers have gone home and returned in the morning to do the unlocking, whilst checking the safety and security of the building before staff arrive.

Furthermore, a 24-hour call-out service means that even at very short notice an officer can be at the premises ready to carry out the necessary checks.

Our fully trained and SIA licensed staff will thoroughly patrol and secure your buildings, in a service tailored to your business needs. Our officers can turn off lights and equipment as needed, whilst also ensuring that windows and doors are securely closed and locked, reducing energy bills whilst also securing your site.


Our locking and unlocking service takes the stress and strains away from this person as our licensed mobile patrol officer will attend your site and perform these duties on your behalf.  

The Lock and Unlock service can also have added value such as escorting staff to their vehicles or work destination during dark hours or simply assisting vulnerable staff members who have to shut down the premises at night.

Having a designated lock-up person means that when someone stays late, the lock-up person does as well. This alongside comprehensive building security makes employees feel safe allowing them to be more productive. 

Open and lock doesn’t stop a burglar from breaking into the property at night but you will have the assurance that all lock-up procedures were followed and as a result, a potential insurance claim would not be affected.

Additionally, we can integrate other actions into the service such as shutting down computers and checking any electrical equipment which not only reduces the chance of a fire but can reduce your electrical running costs.
