Reprogramming Car Keys
Transponder keys are thought to be more secure for vehicles and more difficult to copy by thieves. However, a key might need to be reprogrammed when it becomes damaged or lost.
You can change the key fobs you own however, you must be aware of the correct process. You should have these items to get the best results:
Keys
Modern cars require a transponder keys to operate. This is a security feature and anti-theft protection. These keys are programmed by a locksmith or an authorized dealer to work with the car's systems and specific model. They are costly to replace in the event of loss therefore, you should have spares in your car. You can find key fobs to replace them in online stores as well as many brick and mortar auto shops. But how do you know that the new one you purchased is genuine? Can you tell whether it has been programmed to work with another vehicle or if it could be reprogrammed to fit your vehicle?
If you are planning to program an entirely new key, the first step is to make sure that your car is on and running. Insert the key you wish to program into the ignition without turning it. You will only have a couple of seconds before the car's system reverts the commands and exits programming mode. This is why it is important to be quick and not pause between steps. Turn off the engine to prevent this. Turn the key from "on" to "off" to test the system. The door locks should be able to cycle, and you will hear a chime signalling that the process was successful.
Certain newer vehicles utilize rolling keys to keep thieves from using stolen keys to open the car. This feature is still vulnerable to a technique known as replay attack, which allows thieves to record the signal from the key fob on the vehicle and then replicate it to unlock the car. To stop this, manufacturers have introduced a security feature called CAN bus protocol to stop hacking attempts.
Some manufacturers use a special encryption on their keys, which cannot be decoded by an ordinary program. These kinds of cars will need to be programmed by a professional, and you should only try this only if you've worked with electronics. It's a good idea to consult the owner's manual for your car or look up the manufacturer on the internet, since these steps vary by vehicle type.
Transponder chips
Car keys with transponder chips require special reprogramming in order to function. Any hardware store can offer you an entirely new car key, however the real challenge lies in implementing it to your car. The key needs to be programmed to match the exact identification number of your vehicle, or else it won't start.
Transponder chips are a standard feature of modern cars and are designed to stop car theft. The chip is a microcircuit which transmits a radio frequency signal when the key is placed in the ignition. The car detects the signal and begins the engine only if the signal is in line with the original that was programmed into the vehicle. The car also shuts down if the frequency is invalid. This makes it more difficult for thieves who are not experienced to wire a vehicle and then start it.
The key and the chip are connected 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 creates a signal which is absorbed by the coil before being sent to the key's identification number. The key's identification number is returned to the car and the engine will start when the identification number is in line with.
There are many ways to program a key transponder, however all of them require the use of a specific tool. You can buy these tools online or at most automotive locksmiths. These tools are not inexpensive, but they are vital for programming the chip in your car.
You could also use a reprogrammable key that was previously programmed for a different vehicle. In this case, ensure that the key has not been damaged or the transponder is not altered in any way. To check this, you'll need scanners or computers with an USB port to read the chip and determine its identity.
Reprogramming a transponder is a simple procedure, but requires specific software. It also requires an scanner tool. It is recommended to contact an auto locksmith for help for those who are new to the process. It is also recommended to avoid purchasing secondhand keys, as they're likely to be programmed and won't work with your car.
