Make Emergency Metal Spare Key With 9V Battery or Coca Cola Cap Improved Version to Plastic

Recycle: Make metal Keys in minutes By using 9v battery or coca cola bottle caps or beer bottle caps, we can make emergency spare key for lock, The resulted key can be used up to 10 times, so make it in less than 4 mins and keep in your wallet and use in an forgotten or an emergency situation.It is the most Useful and easiest life hack using Expired 9V battery or a coca cola cap.

In the previous version i made it was with plastic card or tic tac container and many of viewers are saying about bending and breaking of keys inside lock so i made this video as an improvement to plastic keys here it too cost nothing than used batteries or bottle caps.

one of my viewer commented that plastic key was broken inside the lock it can be removed with forceps of use a safety pin.

Don't apply more pressure if its not working just remove and correlate with original key.

Requirements:
Expired 9v Battery

Cool drink bottle metal caps

Clear tape and a lighter or a candle

Step 1: Smoke One Side of the Key

Take the key you want to make spare key, Use lighter and flame one side of the key smoke accumulates on the surface of the key now place key aside and let it cool down

Step 2: Make the Trace of Key

By using the clear tape stick it on the smoky side of the key and the print of the key transfer to the gummy surface of the that means smoke particles sticks to tape and it gives clear print of the key

Step 3: 9V Battery Part

Remove the outer metal layer of battery and cut the four rough edges you will get a sheet make it flat just by applying pressure with hammer then take the tape having key print and stick it over the sheet and by using scissor cut the metal sheet accurately we will get a metal copy of our key.

Step 4: Bottle Cap Part

By hammering make the bottle cap flat and stick the tape and cut the shape of key in this case you will get a small key because of cap size but surprisingly what i observed was it was not bending and working perfectly.

Step 5: Testing Part

before testing compare your keys with original and then test them don't apply over pressure or don't forcibly pull them inside, my personnel experience is they are working fine in case of battery metal key it is slightly bending on usage but not braking inside and in case of coke cap its good but the key was little it was not bending .

be careful while cutting it is metal it may cut.

hope this may be helpful than the plastic version i made and thanking you for all your encouragement.

bye bye.

I am not sure what brand lock that was in your video, but these days most the major brands have levels of security that they rate locks. It's on the package, rated from like 3 to 9, 9 being pretty stout. I can't remember ever seeing a Masterlock having such undefined cuts on a key, not even a level 3. Come to think about it, not even a decent suitcase key/lock. The lock in the video looks like a Dollar Store lock, and well, you can open one of those with anything remotely shaped like a key. My other issue is the method of manufacture. I have snips made for left and right-hand cuts in metal, without this ability, it is very difficult to get definition, the kind a real key would require. Scissors seem like they shouldn't even be considered to cut a key for a lock that was secure to begin with. I would think a Dremel tool would be the most common tool that any Jones would have that is capable of the required definition. I'm going to reserve utter disbelief until I try your method, on what I would consider a secure lock.

Most propably you can keep the replacement key from breaking in the lock by just using a small screwdriver or bent strip of spring metal for the actual turning action. This way there is no stress on the "key" as it just triggers the pins.

or by making two and using super glue to glue them together..........

ya that's good idea thanks for update

[Azze01]

Thanks. Oh and, maybe it would be worth mentioning that your method only works for the very incomplicated, straightforward keys. Any mechanism with multiple pinning system (like the ones additionally notched at the side ridges or sporting ball inlays) will not be cheated by an imitation like this. Would be a waste of time

Thank you for sharing - it is a fascinating video.

When I was a kid (early 70's) we used the plastic covers off of coffee cans to make keys. They would easily squeeze between the "ridges" on the sides, and were stout enough to set the pins. You couldn't unlock a car door with them, but you could use them in the ignition as the switches had turning "wings". We just cut a piece close to size, held it and the key together in a vise notches up, and cut with an xacto knife. Then trimmed the excess and was ready to drive. Worked for me for about two years beginning at 14... my parents came home early one night and I got beat to a pulp... lol

lol if my parents had seen this project may be i would be beaten up haha

Awesome project! Check out my project on how to make battery clips from 9V batteries.
