How to Start My Car Without Chip Key

 

Transponder keys, chip keys, or key FOBs, commonly known, are traditional metal keys with an anti-theft chip embedded in the plastic cover.

The key is one of the layers that make up vehicle safety systems. The easiest way to steal an automobile is to utilize the original key. Like in the movies, the thieves would take keys for a minute and leave imprints that they could later recreate.

To prevent this, manufacturers developed transponder chips. Without one, even a perfect replica of a key will not start the engine because there is no chip to emit the RFID (Radio Frequency Identification).

When the key is inserted into the lock, the automobile determines whether the unique RFID frequency can be detected; the chip within a transponder key generates a very weak signal that can only be registered near the lock. If your automobile has a transponder key, a thief will have no choice except to steal your keys, which you will notice sooner and react to prevent the theft.
