To prevent a thief gaining access using a coat hanger, smooth door locking buttons should be purchased. Mark all valuables with your driver's licence number and apply an identification decal. These decals are available at no cost from your police department. Keep an inventory of all accessories and items with serial numbers for identification, such as tools, etc. Do not hesitate to report suspicious persons in or around motor vehicles.
Time is of the essence.
Be able to supply a list of items stolen, with serial numbers or any identifying marks if possible. Do not damage or remove any evidence before police arrive.
