This technology helps prevent car theft because it makes hot-wiring useless.

If you are experiencing these problems, it is time to contact an auto locksmith to replace your keys.

Smart Key

Smart keys take technology a step further. The key instead of being the standard key, has an electronic device that communicates with your vehicle, allowing it to perform standard tasks like unlocking the doors and trunk, as well as activating the car with a push a button. Although they are convenient they are more expensive than transponder keys that are traditional due to their integrated technology.

To work, these smart keys have the LF (low frequency) transmitting antennas inside and outside the vehicle. They activate when you open the trunk or door. The LF signal travels through the body and doors to reach the interior electronics that recognize it as an authentic smart key. Once it is recognized, the car disables its immobilizer and starts the engine.

However, smart keys can also be a safety risk. How Stuff Works Electronics says that if you're far from your car someone could be able to intercept the low frequency signal and begin your car by putting it in a compatible ignition. Certain manufacturers restrict the range of transmission to 10cm to reduce the risk.

The model year and type of vehicle you drive can affect the cost of replacing a key. In general, older vehicles have lower replacement keys than modern models.
