Reprogramming Car Keys
Transponder keys for car keys are believed to make vehicles safer and are harder for thieves to duplicate. However, a key might need to be reset if it becomes damaged or lost.
You can change the programming of your key fobs at home, but you must be aware of the proper procedure. You must have these things to achieve the best results:
Keys
The majority of modern vehicles require a transponder key in order to operate. This gives security and protection against theft. These keys must be programmed to your particular car and its systems by a certified dealer or locksmith. It is expensive to replace them if they're lost, so it's better to have spares available. You can purchase key fobs that can be replaced in online stores and numerous brick-and-mortar auto shops. How can you be sure that the one you bought is genuine? Do you know whether it was programmed for another car or if it can be reprogrammed for yours?
To program a new car key, first make sure that your vehicle is running. Insert the key that you wish to reprogramme into the ignition, but don't turn it. There are only a few seconds left before the system will reset all commands and then exits the programming mode. It is essential to be quick and don't be patient between each step. To prevent this from happening, shut off the engine. You can check the car's system by turning the key to the "on" position and then back to the "off" position. The door locks should cycle and you will hear a chime to indicate that the procedure was successful.
Some newer vehicles use rolling keys to stop thieves from using stolen keys to start the car. This feature is still vulnerable to a technique dubbed a replay attack. It allows thieves to record and later duplicate the signal generated by the vehicle key fob to unlock the car. To counter this, manufacturers have added a security feature called the CAN bus protocol to stop hacking attempts.
Certain manufacturers have a unique encryption on their keys, which can't be decoded with a simple program. You should only try this process if your experience is with electronic devices. It is recommended 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 a special reprogramming to work. While any hardware store can cut keys for you, the main issue is how to integrate it to work with the specific car you own. A key that has been reprogrammed will need to be matched with the exact identification number of your vehicle otherwise it won't even start the engine.
Transponder chips, which are used to stop theft of cars are a standard feature of modern cars. The chip is a small microcircuit which transmits a radio-frequency signal when the ignition key is put in. The car is able to detect the signal and begins the engine only if it matches the one programmed in the vehicle. The car will also shut down if the frequency is not valid. This makes it much harder for thieves who are not experienced to hot wire a vehicle and then start it.
A circuit board equipped with an induction coil that connects the key to the chip. When the key is placed in the ignition it creates an electromagnetic field around the transponder. This creates a signal which is received by the coil and sent to the key's identification. The key's identification number is then transmitted back to the car and the engine is started if the identification number matches.
There are many ways to program a transponder key, however, they all require an instrument that is specifically designed for the purpose. These tools can be purchased on the internet or at most auto locksmiths. These tools are not cheap but are essential to program your car's chip.
You could also use a reprogrammable transponder key that was previously programmed for a different vehicle. In this case you'll need to make sure that the key isn't damaged or the transponder has been altered in any way. You can read the chip with a scanner, or a computer that has an USB connector.
Reprogramming a transponder is a simple procedure, but it requires specific software. It also requires the use of a scanner. It's best to ask an auto locksmith for assistance in case you're not an expert. You should also avoid buying second-hand keys, since they're probably already programmed and won't be compatible with your car.
EZ Installer
Prior to recently the time when car owners wanted to replace their keys were required to go to a dealer to have it digitally paired to the vehicle. This is because in order to make modern keys work they must be "paired". This required expensive and complex equipment that was only available to dealers.
