Reprogramming Car Keys
Car keys with transponders are believed to make cars more secure and are more difficult for thieves to duplicate. However, a key may need to be reset when it becomes damaged or lost.
You can program key fobs yourself however, you must be aware of the correct procedure. For the best results you should have the following items:
Keys
Most modern vehicles require a transponder fob or transponder keys to work, which provides security and anti-theft protection. The keys are programmed by a locksmith or authorized dealer to function with your car's system and the specific model. It is expensive to replace them if they are lost, so it's best to keep extras on hand. You can find replacement key fobs in online stores and many brick and mortar auto shops. But how do you know that the one you have bought is genuine? Can you tell whether the unit is programmed to work with a different vehicle or if it could be programmed again?
If you're looking to program an entirely new key, the first step is to make sure that your car is on and running. Insert the key that you wish to program into the ignition, but don't turn it. There are only a few seconds before the car's system reverts the commands and exits programming mode. Therefore, it is essential to move fast and not wait between steps. To avoid this happening, turn off the engine. You can check the car's security system by turning the key to the "on" position and back to the "off" position. The door locks should cycle and you'll hear a chime to indicate that the process has been successful.
Some newer cars use a rolling key technology, which keeps thieves from using stolen cars' key to start it. This feature is still vulnerable to a technique dubbed replay attack, which allows thieves to record the signal received from the key fob on the vehicle, then reproduce it to open the car. To counter this, manufacturers have introduced a security feature called CAN bus protocol to stop attacks on hacking.
Certain manufacturers also have special encryption on their key fobs that cannot be decoded with an ordinary program. These types of vehicles will need to be programmed by a professional. Therefore, you should only attempt this process only if you've worked with electronics. It is a good idea to read the owner's manual of your vehicle or look up the manufacturer online, as the steps differ based on vehicle type.
Transponder chips
Car keys with transponder chips require a special reprogramming to work. While any hardware store can cut keys for you, the main challenge is making it function to work with the specific car you own. A reprogrammed key will need to match the exact identification number of your vehicle or else it won't be able to start the engine.
Transponder chips are a common feature of modern automobiles 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 detects 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 the frequency is not valid. This makes it more difficult for novice car thieves to connect a vehicle with hot wires and start it.
The chip and the key are connected by a circuit board that includes an induction coil. When the key is placed in the ignition, a magnetic field is created around the transponder. This creates a signal which is absorbed by the coil and then transmitted to the key's identification. The key's identification number is transmitted back to the car, and the engine starts when the identification number is in line with.
There are a variety of ways to program a transponder, however all of them require an instrument that is specifically designed for. These tools are available on the internet or at most auto locksmiths. They are not cheap, but they're vital for programming the chip to your car.
You can also utilize a transponder that is reprogrammable that was previously programmed for another vehicle. In this case, make sure that the key has not been damaged or that the transponder isn't altered in any way. To check this, you'll need scanners or a computer with a USB port to identify the chip and establish its identity.
Reprogramming the transponder is a straightforward process, but requires specific software. It also requires a scanner tool. If you're new to the process, it's best to seek out the help of an auto locksmith. It is also recommended to avoid purchasing second-hand keys, since they're probably already programmed and will not work with your car.
EZ Installer
In the past, car owners who wanted to replace their key fob were forced to visit a dealer to have it electronically linked to the vehicle. It is because to make modern keys work they have to be "paired". This required expensive and complicated equipment that was only available to dealers. The EZ Installer by Car Keys Express simplifies the process of pairing modern keys with vehicles used by retailers and locksmiths.
