Reprogramming Car Keys
Transponder keys are said to be more secure for cars and are more difficult to copy by thieves. However, a key may need to be reprogrammed in the event that it is damaged or lost.
You can program key fobs yourself however, you must be aware of the proper procedure. For the best results, you should have the following items:
Keys
Most modern vehicles require some kind of transponder fob or transponder keys to operate, providing security and anti-theft protection. The keys must be programmed to your specific vehicle and its features by a licensed locksmith or dealer. They can be costly to replace in the event of loss, so you should have spares in your car. You can also find replacement keys fobs in various online stores and in a variety of brick-and-mortar automotive shops. How can you know that the one you bought is genuine? Do you know whether the unit is programmed to work with another vehicle or if yours can be programmed again?
If you are planning to program a new key, the first step is to ensure that your vehicle is operating. Insert the key you want to program into the ignition, but do not turn it. There are only a couple of seconds before the car's system resets commands and leaves programming mode. This is why it is crucial to move quickly and not wait between steps. Stop the engine to avoid this. You can check the system of your car by turning the key to the "on" position and then back to the "off" position. There should be a chime to indicate that the process was successful. The door locks will cycle.
Certain newer vehicles have rolling key system, which keeps thieves from using a stolen vehicle's key to open it. This feature is still susceptible to a technique called replay attack. It allows thieves to record and later reproduce the signal from the car key fob to open the car. To prevent this, manufacturers have added a security feature called the CAN bus protocol to thwart attacks on hacking.
Certain manufacturers employ a specific encryption on their keys, which can't be decoded with an ordinary program. It is best to only attempt this method if you have experience is in electronic devices. Refer to the manual for your car or go to the website of the manufacturer to learn how to program it. The steps are different according to the type of vehicle.
Transponder chips
Car keys with transponder chips need special reprogramming to work. While any hardware store can cut a new key for you, the real problem is to make it work to work with the specific car you own. A key that has been reprogrammed will need to be matched with the specific identification number of your vehicle, or it won't start the engine.
Transponder chips are a common feature of modern cars and are designed to prevent car theft. The chip is a microcircuit which transmits a radio frequency signal when the key is inserted in the ignition. The car can detect the signal and begins the engine only if the signal matches the original one that was programmed into the vehicle. The car also shuts down if a frequency is not valid. This makes it much more difficult for thieves who are not experienced to hot wire a vehicle and then start it.
A circuit board that has an induction coil that connects the chip to the key. When the key is placed in the ignition it creates a magnetic field created around the transponder. This generates a signal that is amplified by the coil which transmits it to the key's identification number. The key's identification number is then transmitted back to the car and the engine will start if the identification number matches.
There are several methods to program a transponder key however, they all require an appropriate tool. You can buy these tools online or at most locksmiths in the automotive industry. These tools aren't inexpensive, but they are vital for programming the chip in your car.
You could also make use of a transponder key that can be reprogrammed that was previously programmed for another vehicle. In this scenario, ensure that the key isn't damaged or the transponder is not altered in any way. To do this, you'll need scanners or computers with a USB port to read the chip and determine its identity.
Reprogramming the transponder is a straightforward process, but requires special software. It also requires an scanner tool. It is best to consult an auto locksmith for help if you're a novice. It is also recommended to avoid purchasing secondhand keys, as they're likely to be programmed and won't work with your car.
