If you have a car with an ignition key, there are a few things you can do to remove it. The first is to try to pry the key out by using a plunger. If that doesn’t work, you can try using a vacuum cleaner and bucket to suck the key out from the ignition housing. If that doesn’t work, you can use a heat gun and an oven to heat up the metal part of the key so it pops out easily.
