A modular access tool for operating door handles and door locks of motor vehicles from the exterior of the motor vehicle. The access tool is provided in sections which are removably attachable to one another such that the overall operative length is adjustable in discrete steps. A working head, such as a loop, a hook, or a magnet is attachable at the end of the access tool. Optionally, an illumination light may be attachable at the end of the access tool. Sections join together by threadless interference based detent devices.
