Introduction: A Car Key Made From a Ratcheting Wrench

A classy car should have a classy and unique car key. I took a 12mm ratchet spanner and tried to replicate the form of the original car key. With only a few basic tools like an angle grinder, rotary tool and few metal files I successfully managed this quite precise job to came true.

How I did it - you can check by looking DIY video or you can follow up instructions below.

For this project you will need:

Materials:
12mm ratcheting spanner / wrench

Tools:

Angle grinder with cutting and grinding discs

Vise and clamps

A rotary tool with cutting discs, sanding drum & engraving bits

Small metal files

Metal polishing and buffing pads with polishing compound

Permanent marker, ruler, and sharp scraper for marking

A bit of patient and precise work:)

Step 1: Modifying 12mm Ratchet Spanner

Cut ratcheting wrench to needed length. After that flattened to needed thickness with grinding disc.

Step 2: More Shaping

Used caliper to mark proper width and with rotary tool + drum sander bit shaped to needed witdht.

Step 3: Replicating Original Key Pathern

Covered flattened surface with black marker and scraped original key outer shape by using the key as a template.

Step 4: A Bit More of Copy/paste

When the outer shape was more or less done, I moved to the pair of grooves on the flat surface. Measured and marked with the caliper on a black surface. After that used a rotary tool to cut 1mm dept grooves.

Step 5: Finetuning to Perfectness

With a rotary tool and engraving bit finetuned every single groove and bump to perfect match.

Step 6: Finishing Till Perfect Shine

Sanded with scotch Brite pad on a palm sander. Later on, finished by polishing with two different metal polishing compounds and buffing discs.

Step 7: Final Result and a Test Run

The result was mind-blowing - shiny, unique and what is most important - it turned the car!

    I love this. I think using a 10mm wrench would have been funny.

    You beat me to it although if he used a 10mm that would assure that he was going to lose his car key.

    I love this idea. Awesome work. I would only change one thing. I would use a 10mm spanner. I seem to always loose that size and this would be nice as a backup.

    I been a diesel mechanic for about 20 some years, always the 10mm gets lost but as of this year I have lost two 8mm sockets and two 8mm wrenches. I guess everything is just getting smaller.

    Yes, but then you'd lose your key.

    You cannot use the 10mm. The gremlins that live in tool boxes love them. They would sneak out and steal your key. No wrench and no key double screwed. LOL I lose them all the time too. Its such a popular size it never seems to make it back to its home.

    great job, great idea, and opens the door for all kinds of things to turn into keys lol. but the fact that you didnt spin it around on the ratcheting ring when it was done, kind of triggered me a little, i thought that would be one of the main reasons for making this! lol

    What I love about this is it's all hand-crafted. Please don't lose that key, it's stunning.

    Did you ever notice that keys are generally made of a soft metal like brass? That is so the lock's tumblers don't wear much. Vanadium Steel makes for a really hard key and might promote increased lock wear. Something to think about if you've got a classic car. Otherwise pretty neat.

    I love it.
    That's the most awesome key ever.
    Now someone needs to give me a nice classic so I can make the key.

    Btw, if we are gear heads enough to love the key, you know we need information on the car right?
