Transponder keys are said to be more secure for cars and harder to copy by thieves. However, a key might need to be reset in the event that it is damaged or lost.
You can reprogram key fobs yourself, but you must know the correct process. It is essential to have these items to get the most effective results:
Keys
Almost all modern cars require a transponder key or fob in order to operate, providing security and anti-theft protection. The keys must be programmed to your particular car and its systems by a licensed dealer or locksmith. They are costly to replace if they are lost and you should keep extras handy. You can locate key fobs that can be replaced in online stores and many brick-and mortar auto shops. How can you know that the one you purchased is genuine? Do you know whether the unit has been programmed to work with a different vehicle or if it could be programmed again?
If you want to program an entirely new key, the first step is to ensure that your vehicle is on and running. Insert the key you want to reprogram into the ignition without turning it. There are just a few minutes before the system resets all commands and then exits the programming mode. This is why it is essential to be quick and not be able to wait between steps. Stop the engine to stop this. 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 be able to cycle.
Certain newer vehicles have rolling key system, which keeps thieves from using a stolen car's key to open it. This technology is still vulnerable to a technique known as a replay attack, which allows thieves to record the signal of the vehicle's key fob, then reproduce it to unlock the car. To stop this, manufacturers added the security feature known as the CAN bus protocols to stop hackers from gaining access to the vehicle.
Certain manufacturers have a unique encryption on their keys that cannot be decoded using an easy program. You should only try this process if your experience is in electronics. Check the manual of your car or look up the manufacturer's website to learn how to program it. The steps will vary according to the type of vehicle.
Transponder chips
Car keys with transponder chips require special reprogramming in order to work. While any hardware store can cut keys for you, the main problem is to make it work to work with the specific car you own. A reprogrammed key will need to match the exact identification number of your vehicle otherwise it won't even start the engine.
Transponder chips are a common feature of modern automobiles and are designed to stop car theft. The chip is a microcircuit that emits a radio frequency signal when the key is inserted into the ignition. The car is able to detect 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 a frequency is invalid. This makes it more difficult for car thieves with no experience to connect a vehicle with hot wires 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 around the transponder. This creates a signal that is amplified by the coil which transmits it to the key's identification number. The key's ID number is sent back to the vehicle and if it is in line with the engine will start.
There are many methods to program a transponder keys, but they all involve using a special tool. You can purchase these tools online or from most locksmiths in the automotive industry. These tools aren't cheap but are essential for programming your car's chip.
You may also use a reprogrammable transponder key that has been previously programmed for a different vehicle. In this instance, you must ensure that the key has not been damaged or that the transponder has not been altered in any way. To check this, you can use a scanner or a computer equipped with a USB port to read the chip and determine its identity.
The process of reprogramming a transponder key is quite simple, but it requires special software and a scanning tool. If you're just beginning it is recommended to seek the assistance of an auto locksmith. You should also avoid buying second-hand keys, since they're probably already programmed and will not work with your vehicle.
