Keys

Almost all modern cars require some kind of transponder key or fob to work, which provides security and anti-theft protection. These keys are programmed by a locksmith or an authorized dealer to work with the car's systems and the specific model. They are expensive to replace if lost therefore, it is recommended to keep spare keys in the car key programmer. You can also find replacement keys fobs at various online stores and in many brick-and mortar auto shops. How do you ensure that the one you have bought is authentic? Are you able to tell if the unit has been programmed to work with another vehicle, or if it can be reprogrammed?

You only have a couple of seconds before the car key programming cost's system resets commands and leaves programming mode. It is crucial to be quick and don't wait between each step.

Transponder chips

Car keys that feature transponder key programming chips need special reconfiguration to work. While any hardware store can cut a new key for you, the real challenge is making it function to work with the specific car you own. The key needs to be programmed to match the exact identification number on your car, or else it will not start.

Transponder chips, used to stop theft of cars are a standard feature of modern cars. The chip is a microcircuit that transmits a radio frequency signals when the key is inserted into the ignition. The car then scans for the signal and begins the engine if it matches the original one that was programmed into the vehicle. The vehicle is also programmed to shut down when it detects an incompatible frequency. This makes it difficult for novice car thefts to hot-wire a vehicle and then turn it on.

The key and the chip are linked by an electronic circuit board that contains an induction coil. When the key is placed in the ignition, it creates an electric field around the transponder. This generates a signal that is taken up by the coil before being sent to the key identification number. The key's identification number is returned to the car and the engine is started if the identification number matches.

There are many methods to program a transponder key, however, they all require a special tool. These tools can be bought through the internet or from many automotive locksmiths. These tools are not inexpensive, but they are vital to program your car's chip.
