It is not always only the admin staff has to do the maintenance activities. Even you could initiate a risk mitigation plan. For example, you are the person who are going late from office to home every day. On one day you have noticed that because of some unexpected reason the watchman has left you alone at office taking the keys with him thus leaving you in dark. You could not come home just because you are stuck in office. You may not get the proper commutation when the office is located in the outskirts of the city.
In such situations all that you could do is to hire the garage door repair since you could not ask your manager to come to office for the reason that you are not able to manage to get back to home. All that you could do is to hire the experts whom would unlock and also lock the garage door so that you could take your vehicle alone outside and thus reach home safe. You could get complete details from your manager and then take necessary action steps to unlock the door locking system once after all the validations are completed by the service person.
Also, since the service experts would not want to get involved in any of the illegal activities that are done by certain parties just to steal the cars that are parked in some ready to demolish garage, you could rely on the most popular and most sincere online services who could help you during tough times. Before or after you request the services you could also inform the head of administration department about what you have done so that they know the reason behind your decision. Just be safe but also let the management know everything that happened.
