Transponder keys for car keys are believed to make vehicles safer and are less likely to be duplicated by thieves. Keys may need to be programmed again in the case of damage or lost.

You can program key fobs yourself, but you must know the correct procedure. You should have these items to ensure the best results:

Keys

Nearly all modern vehicles require a transponder key or fob in order to work, which provides security and protection against theft. These keys must be programmed to your particular vehicle and its systems by a licensed locksmith or dealer. They are costly to replace in the event of loss, so it is recommended to keep spare keys programmed in the car. You can locate key fobs that can be replaced in online stores as well as many brick and mortar auto shops. How do you ensure that the one you have bought is authentic? Are you able to tell whether the unit is programmed to work with another vehicle or if yours can be programmed again?

To program a new car keys, you must first ensure that your car is running. Insert the key that you want to reprogramme into your ignition, but don't turn it. There are only a few seconds before the system resets all commands and then exits the programming mode. This is why it is important to be quick and not pause between steps. Shut off the engine to prevent this. Switch the key from "on" to "off" to test the system. The door locks should cycle, and you will hear a sound that indicates that the procedure was successful.

Certain newer vehicles have rolling key technology that prevents thieves from using stolen cars' key to start it. This technology is still vulnerable to a technique known as replay attacks, which allows thieves to record the signal received from the key fob of the car and then replicate it to unlock the car. To prevent this, manufacturers introduced security features known as the CAN bus protocols to ward off hackers from gaining access to the vehicle.

Certain manufacturers have a unique encryption on their keys, which cannot be decoded using an easy program. You should only attempt this method if your previous experience is in electronic devices. Consult your car's manual or go to the website of the manufacturer to learn how to program it. The steps will vary depending on the model of vehicle.

Transponder chips

Car keys with transponder chips require a specific reprogramming to function. While any hardware store can cut keys for you, the real challenge is making it function to work with the specific car you own. A reprogrammed key will need to be matched with the exact identification number of your vehicle otherwise it won't even start the engine.

Transponder chips, used to stop theft of cars, are a common feature of modern automobiles. The chip is a microcircuit which transmits a radio frequency signals when the key is inserted into the ignition. The car then detects the signal and starts the engine if it is in line with the original frequency that was programmed into the vehicle. The car will also shut down if the frequency is invalid. This makes it more difficult for thieves with no experience to wire a vehicle hot and then start it.

The key and the chip are linked by the circuit board which includes an induction coil. When the key is put in the ignition it creates a magnetic field generated around the transponder. This creates a signal that is absorbed by the coil, which transmits it to the key's identification number. The key's identification code is returned to the car and the engine is started when the identification number matches.

There are several ways to program a transponder, however all of them require a special tool. These tools can be bought online or from most automotive locksmiths. These tools aren't inexpensive, but they are vital to program your car's chip.
