Spray paint hack for differentiating between keys in a hurry.

  1. Choose spray paints
  2. Color them from close distance in a plastic bag
  3. Leave hair dryer on side of a bag for 5min (turn other side, paint & wait again)
  4. Put them on key-ring and always know without guessing correct key
<p>great idea, but i wonder if paint will stay inside the lock when the keys are used.</p>
