How To Make A “Car Hero” Key Box


for this project I’m going to show you
how to eliminate the fear and panic of
losing your car keys and the frustration
of getting locked out by your kids
especially when your keys are locked
inside with them let’s start this
project with a 45-pound carabiner hook
magnet the bottle of kid’s vitamin
gummies save the gummies for your kids
because all we’re really after here is
the plastic container and the reason I
chose this bottle is because it’s fairly
cheap and the mouth is wide enough for a
key fob to slide in and out without any
problems at all now rather than making
our own magnetic key box you might be
wondering why not just go to the store
and buy a premade case instead the
answer is that you could but they aren’t
big enough to store transponders and key
fobs so they won’t work very well with
newer vehicles the magnets aren’t
impressively strong either I tested the
store-bought version on a flat steel way
and found that the most it could handle
was 5 pounds barely on the other hand
you can find super magnets at the
hardware store that claim to hold up to
45 pounds now in practice I found the
most they’re really good for is about 25
pounds which is nearly half of what’s
advertised but despite the inflated
claim you can still see they’re at least
5 times stronger and that will make all
the difference now to make a car hero
key box we’ll need our magnet secured
firmly to the lid of the bottle and I
found the easiest way to do that is with
a flathead screwdriver and a propane
torch of course if you don’t have a
propane torch you can always use a BBQ
igniter instead get your screwdriver and
carefully heat the tip for a few seconds
in the open flame so it gets good and
hot then quickly press it into the top
of the lid so it makes a hole that’s
slightly offset from the center while
it’s still hot make another hole in line
with the first you should end up with a
nice clean slit right down the center
now when your screwdrivers cool down a
bit gently pry at the edges of the
bottle cap liner and pop it out so you
can modify the underside of the cap heat
the screwdriver again but this time
rather than poking all the way through
the cap carefully carve a channel out of
the inner plastic lining around half an
inch long on either side of the slit
take your time and do a good job because
it’s really important that you don’t
burn into the yellow part of the cap
underneath with this little channel
carved out go ahead and unhook the
carabiner from the magnetic base so you
can flip it over and press the carabiner
clip down into the cap locking it into
place with the magnetic side facing up
now if you look closely at the underside
of the cap it should start to make sense
how this is going to come together try
hooking the carabiner back in place and
you’ll most likely find that it’s just
barely enough clearance to get it lined
up with the hole but with a little
persistence and some
from your screwdriver you should be able
to pull it all the way through it’s
locked together pretty tight now and
that’s really great because it means
there’s very little chance it’s ever
going to come off by accident at this
point you’re pretty much done so go
ahead and clip the spare set of keys
onto the carabiner and that’s it you’ve
got yourself a super-strong and weather
resistant car hero key box that’ll
accommodate an emergency set of keys
with room to spare now let’s go one step
further and give it a paint job I
thought it would be fun to try coating
with some abrasion resistant truck bed
coating this stuff is normally used for
lining truck beds but you can see it
gives the bottle a cool textured look
that’ll help camouflage it a bit so it
blends in better with we’re going to
hide it in a second spray a couple
coatings on the cap as well because it
will help seal the gaps around the
magnet and make the whole thing
water-resistant now since your vehicle
is built on a steel frame you’re super
strong key box will stick just about
anywhere you want and if you look around
for a while you’ll see hundreds of
little nooks and crannies where you
could hide it so pick a place that works
best for you and your peace of mind now
the next time you walk out to your car
and realize your keys are missing you
don’t have to worry about calling a
friend for a ride or breaking a window
to get in instead simply reach for your
emergency key box and a clean set of
spare keys will be waiting there ready
to help you out just like that you’ve
dodged a potentially embarrassing
situation and emerged a car hero instead
saving you time money and maybe even
your pride as well well now you know how
to convert a magnet in a plastic bottle
into a car hero key box it’s over five
times stronger than store-bought brands
and much more convenient to use by the
way try throwing a few hand wipes in
there as well this way if you get a bit
dirty in the process you’ll have
something handy to wipe yourself clean
