Transponder keys are believed to be more secure for vehicles and more difficult to copy by thieves. Keys may need to be programmed again in the case of damage or lost.

You can change the programming of your key fobs at home, but you need to know the right process. For the best results you'll need the following items:

Keys

The majority of modern vehicles require a transponder key in order to operate. This provides security and anti-theft protection. The keys have to be programmed to your specific vehicle and its systems by a certified dealer or locksmith. They are costly to replace in the event of loss and you should keep extras handy. You can also find replacement key fobs in various online stores and in a variety of brick-and-mortar automotive shops. How do you ensure that the one you purchased is authentic?

Certain cars with more modern technology have rolling key system, which keeps thieves from using stolen cars' key to open it. This feature is still vulnerable to a technique dubbed a replay attack. It allows thieves to record and then reproduce the signal received from the key fob of the vehicle to open the car.

Transponder chips

Car keys that feature transponder chips require a special programming to function. Any hardware store can offer you a new car key, but the real challenge lies in implementing it to your vehicle. A reprogrammed key will need to be matched with the specific identification number of your vehicle or else it won't be able to start the engine.

Transponder chips are a typical feature in modern cars and are designed to stop car theft. The chip is a microcircuit which emits a radio frequency signal when the key is put in the ignition. The car then detects the signal and starts the engine in case it matches the original frequency that was programmed into the vehicle. The car will also shut down if a frequency is not valid. This makes it much more difficult for novice car thieves to wire a vehicle and then start it.

The key and the chip are connected via the circuit board which includes an induction coil. When the key is placed in the ignition the magnetic field is generated around the transponder. This generates a signal that is absorbed by the coil and sent to the key's identification. The key's identification number is then sent back to the car and the engine will start when the identification number is in line with.

There are many ways to program a transponder, but all require a special tool. You can purchase these tools online or at most locksmiths in the automotive industry. They are not cheap, but they're essential for programming the chip into your vehicle.

You should also avoid buying second-hand keys as they're probably already programmed car keys and will not work with your car.
