Keys

Modern cars require a transponder keys to operate. This provides security and anti-theft protection. The keys are programmed by a locksmith or authorized dealer to function with the car's systems and specific model. They are costly to replace in the event of loss, so you should have spares in your car. You can purchase key fobs to replace them in online stores and many brick-and mortar auto shops. But how can you tell that the new key fob you bought is genuine? Can you tell whether the unit is programmed to work with another vehicle or if it could be programmed differently?
To program a new car key you must first verify that your vehicle is running. Insert the key you'd like to reprogramme into your ignition, but don't turn it. You will only have a couple of seconds before the car's system resets the commands and exits programming mode. This is why it is essential to move quickly and not wait between steps. To prevent this from happening, turn off the engine. Change the key from "on" to "off" to test the system. You should hear a chime to indicate that the process was successful. The door locks will cycle.
Some newer vehicles use rolling key technology to prevent thieves from using stolen keys to start the car. The technology is still susceptible to a technique dubbed replay attack 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 have added an additional security feature known as the CAN bus protocol to prevent attacks on hacking.
Some manufacturers use a special encryption on their keys that cannot be decoded using an ordinary program. You should only try this method if your previous experiences are with electronics. It is a good idea to refer to your car's owner manual or look up the manufacturer on the internet, since the steps differ based on car model.
Transponder chips
Car keys that feature transponder chips require special reconfiguration to work. Any hardware store can offer you a new car key, but the real challenge is in integrating it with your vehicle. A reprogrammed key will need to be matched with the specific identification number of your vehicle otherwise it won't even start the engine.
Transponder chips are a common feature in modern cars and are designed to stop car theft. The chip is a tiny microcircuit that transmits a radio-frequency signal when the ignition key is placed. The car can detect the signal and starts the engine only if the signal is in line with the original that was programmed in the vehicle. The car will also shut down if a frequency is invalid. This makes it harder for thieves with no experience to hot-wire a vehicle and then start it.
A circuit board with an induction coil connects the chip to the key. When the key is inserted into the ignition, it creates an electromagnetic field around the transponder. This generates a signal that gets taken up by the coil, which transmits it to the key's identification number. The key's identification number is returned to the car and the engine is started when the identification number matches.
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. These tools aren't expensive, but they are essential to program your car's chip.
You can also utilize a transponder that is reprogrammable that was previously programmed for another vehicle. In this case, you'll need to make sure that the key isn't damaged or the transponder been altered in any way. To do this, you'll need scanners or computers equipped with a USB port to read the chip and determine its identity.
Reprogramming an transponder is a simple procedure, but requires specialized software. It also requires the use of a scanner. If you're a beginner, it's best to seek out the help of an auto locksmith. Also, avoid buying second-hand keys as they're probably already programmed and won't work with your vehicle.
