Reprogramming Car Keys
Transponders in car keys are thought to keep vehicles safer and are less likely to be duplicated by thieves. However, keys may require reprogramming if it becomes damaged or lost.
You can reprogram your key fobs at home, however you must be aware of the proper procedure. For the best results you'll need the following items:
Keys
Modern cars require a transponder key to operate. This provides security and protection against theft. The keys must be programmed to your specific vehicle and its features by a licensed locksmith or dealer. It's expensive to replace them if they become lost, so it's best to have spares available. You can purchase key fobs that can be replaced in online stores, as well as many brick-and mortar auto shops. How can you know that the one you bought is genuine? Can you tell whether it was programmed for a different vehicle or if it is able to be reprogrammed to fit your vehicle?
If you want 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 just a few seconds before the car's system reverts the commands and exits programming mode. It is important that you be quick and don't delay between each step. Stop the engine to stop this. 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 be able to cycle, and you will hear a sound that indicates that the procedure was successful.
Some newer vehicles use rolling key technology to prevent thieves from using stolen keys to open the car. This feature is still vulnerable to a technique known as replay attack. It allows thieves to record and later reproduce the signal received from the vehicle key fob to open the car. To counter this, manufacturers have introduced a security feature called CAN bus protocol to stop attacks on hacking.
Certain manufacturers employ a specific encryption on their keys that can't be decoded with an easy program. You should only try this process if your experience is in electronics. It is recommended to read the owner's manual for your car or search for the manufacturer on the internet, since the steps differ based on vehicle type.
Transponder chips
Car keys with transponder chips require special programming to function. Any hardware store can offer you a new car key but the real challenge is in integrating it with your vehicle. A key that has been reprogrammed will need to be matched with 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 guard against car theft. The chip is a microcircuit which transmits a radio-frequency signal when the ignition key is inserted. The car then scans for the signal and then starts the engine if it is in line with the original signal that was programmed into the vehicle. The car also shuts down if the frequency is not valid. This makes it harder for thieves who aren't experienced to connect a vehicle to a hot wire and then turn it on.
The key and the chip are connected by a circuit board that includes an induction coil. When the key is put in the ignition the magnetic field is created around the transponder. This produces a signal which is absorbed by the coil, which then transmits it to key's identification number. The ID number of the key is sent back to the vehicle and if it matches the engine will begin to run.
There are a few different ways to program a transponder key, however, all require a special tool. You can purchase these tools on the internet or at many locksmiths in the automotive industry. They are not cheap, but they're essential for programming the chip into your vehicle.
You may also use a reprogrammable transponder key that has been previously programmed for a different vehicle. In this case you'll need to make sure that the key is not damaged or the transponder has been altered in any way. The chip can be read with a scanner, or a computer that has a USB connector.
The process of reprogramming the transponder key is easy, but it will require an expertly designed software and scan tool. It is recommended to contact an auto locksmith for assistance in case you're not an expert. Avoid buying used keys because they could already be programmed and won't be compatible with your vehicle.
EZ Installer
For a long time, owners of cars who required replacement of their key fob had no choice than to visit a dealership to have their key connected to the vehicle. This is because modern keys need to be "paired" to a specific vehicle in order to function and work, which required the use of expensive and complicated equipment that only dealers had access to.
