Lock up services involve ensuring that a property is securely locked, typically at the end of the day or when it is not in use. This may involve checking all doors and windows to ensure they are locked, setting alarms or security systems, and ensuring that no one is still inside the building.

On the other hand, unlock services involve opening a property or building that has been secured. This may involve unlocking doors or windows, deactivating alarms or security systems, and ensuring that the property is safe to enter.

Both lock up and unlock services are important for maintaining the security of a property and preventing unauthorized access. They may be used by businesses, government organizations, and individuals to protect their assets and ensure the safety of their employees and customers. Professional locksmiths and security personnel are typically trained to provide these services efficiently and effectively.
