Introduction: Repairing a Key Fob
Repairing a key fob is a real easy process that anyone can complete. The best part is that you only need a couple of simple tools.
Step 1: Supplies
Your gonna need a few simple tools.
- Small hand saw. anything for cutting really
- Low grit sand. something around 80 grit should work.
- Gorilla glue
- Scrap Wood or plastic ( Masonite is what I used)
-Optional Epilog laser ( Thank you Techshop)
Step 2: Removing the Excess Material
Whatever is left over of what used to be the key ring needs to be removed. Using the saw I cut off most of what is left. I also made sure to cut a small notch for the new part to fit into. This will give it a little more strength. Cutting the notch is much more easily done with the case opened up.
Using the sand paper, I made sure to scuff up the surface where I was gluing to.
Step 3: Cutting the New Part
Now you will need to take some measurements of your current fob to figure out the size of the new one. The main measurement you will need is the radius for the new ring.
For cutting out the new part I was able to use the laser cutter here at techshop. This made it nice since I just quickly drew up a few designs that seemed to be about the right size, then used the one that fit best.
If you don't have access to a laser, you can easily cut these parts out in a variety of methods. Jig saw, hobby knife ( depending on material you use), rotary tool, etc.
Step 4: Glue on the New Part
Once you have a part cut out and ready to go, you just need to glue it on using the gorilla glue.
Be careful to not glue the two sides together, you'll want to be able to get in there in case a battery dies.
Clamp together the part if possible. With some key fobs, it may be near impossible to easily clamp together. Your fob should still hold even if you don't clamp it, but it may be a bit weaker than normal.
And there it is. You now have a fully working key fob. Think of all the adventures you can go on now.
