The Access Tools Heavy Duty Button Master tool, for vertical lock buttons, is a flexible tool with a snare at the tip, operated by a slide on the tools handle. This tool allows users to to grab a vertical button from any angle required and raise it with ease, unlocking the vehicle easier than ever before, according to the company. The Heavy Duty Button Master features a thicker internal wire that is less likely to kink and curl than the standard Button Master. It also features a more durable and heavy duty tube that is stronger while remaining flexible.
