I had the misfortune to be provided with a broken keycard for my Renault Espace. After some hard work with snips I managed to extract the PCB from the original casing and decided to build a case for it.

As printed and with the included Bambu file there are two colour changes - this enables you to print the sanwich effect that provides the detail on the button symbols and Renault logo.

Insert the PCB and battery and then gently slide the lid into place and secure with a single M3x6mm countersunk head bolt. The bolt will self tap into the tapering hole. The buttons are pressable as there is a thin area that allows just the right deformation.
