How to Replace Broken Car Keys

A major inconvenience that most people don't consider when going about your daily life is the possibility that your car key could break. You might expect that on occasion you'll experience a flat tire or a dead battery, but a broken car key usually doesn't cross your mind. Unfortunately, keys do break. And when they do, it is imperative that you locate your spare key or contact the correct person or company to obtain a new car key. After all, the most important part of a working vehicle is a key to operate it.

  • Use your spare keys until you can obtain new keys for your car.

  • Call your local car dealership's service department to order a new key. If you have a late model car that uses a transponder key embedded with a computer chip to match that of your vehicle you will need to purchase a new key from an authorized vehicle dealership. Expect to pay a large fee for a new transponder key, as they run anywhere from $150 to $250 per key, depending on the make and model of your vehicle.

  • Provide the vehicle service department with the vehicle identification number of your car. The location of the VIN depends on the type of car you drive. It could be on your driver's side windshield, viewable from outside of your car or it could be located on the door panel of the driver's side. VINs are always located on purchase paperwork, insurance information and registration forms. The VIN contains the key code for your specific vehicle, which allows the key maker to know exactly how to cut your new key.

  • Pick up your replacement key and test it on your vehicle.
