You can make homemade jigglers and even find patterns for free online, but these are sturdy, cut well, and probably better than anything someone would be willing to, or capable, of making. I personally bought these for emergency situations where a child might be locked in a hot car and in distress, or for the many times people I know lose their keys (or lock them in the car), and similar situations where non-destructive access is desired and you don't have time or money to get a locksmith. One use will cover the cost of getting a locksmith, and with my luck these jigglers will likely help me save money in the long run.
