The RCBM is used to unlock vehicles with vertical buttons using the Door Jack system. Unlocking the door is as easy as hooking the door lock button with the loop and pulling the control knob. The Remote Control Button Master is a specialty long reach tool that is specifically designed for pulling up vertical buttons. It has the same non-abrasive, non-marring coating as the SQM long reach to protect the doors of the vehicle, and is very flexible to fit any situation. To grab the button, it has a loop with a rubber sleeve around the cable for grip and to protect the button, and to activate it, there is a pull on the end of the tool that makes the loop grip the button.
