Many late model cars come with remote keyless entry by means of a small fob. Since unlocking and starting the engine of your car no longer requires a metal key inserted into a lock, you only need to carry the fob somewhere close to the car.
If you carry a purse, then it is a simple matter of tossing it inside, but if you’re like most guys you need another way to carry it. Of course a pants or shirt pocket will work, but I felt it would be more convenient to carry it on my belt.
Here is my design (after several other attempts) for a simple but effective leather fob case. It is sized to fit my 2020 Honda CRV (2½” x 1.4” x ½”), and can be adjusted easily to accommodate other sizes as it is made up of just two rectangles.
First step is to print out the pattern and cut it out of 4/5 oz veg tan leather. Bevel edges with #0 edger.
Tool the pieces if desired and dye or paint them while they are flat.
Attach line 20 snaps as shown, with the female side attaching both pieces together.
Fold shorter piece over onto itself and rivet together top and bottom with small rivets as shown.
Fold narrow strap over the wider strap and rivet together as shown. Strap to left of rivet in lower image slides over your belt.
Insert key fob into case and close snap. Slide your belt into the narrow vertical strap on the back.
This pattern was designed for a belt 1½” wide. I made several cases with a spring holster clip but found the metal against my skin uncomfortable.
