Reprogramming Car Keys
Transponder keys are said to be more secure for vehicles and more difficult to copy by thieves. However, a key may need to be reprogrammed if it becomes damaged or lost.
You can program key fobs yourself but you must be aware of the proper procedure. You should have these items to get the best results:
Keys
Most modern cars require a transponder key to operate. This provides security and anti-theft protection. These keys are programmed by a locksmith or an authorized dealer to function with your car's systems and specific model. They are costly to replace in the event of loss, so you should keep extras handy. You can purchase replacement key fobs in online stores and numerous brick-and-mortar auto shops. How can you know that the one you bought is genuine? Can you tell whether the unit has been programmed to work with a different vehicle or if yours can be programmed again?
To program a new car key you must first verify that your vehicle is operating. Insert the key that you'd like to reprogramme into your ignition, but don't turn it. You have only a few seconds before the system resets all commands and then exits the programming mode. Therefore, it is crucial to move fast and not wait between steps. Turn off the engine to prevent this. Switch the key from "on" to "off" to test the system. The door locks should cycle and you'll hear a chime signalling that the process has been successful.
Certain newer vehicles have rolling key technology that stops thieves from using a stolen vehicle's key to start it. This feature is still susceptible to a technique dubbed replay attack. It allows thieves to record and then reproduce the signal received from the key fob of the vehicle to open the car. To counter this, manufacturers have added a security feature called CAN bus protocol to thwart attacks on hacking.
Some manufacturers also use special encryption on their key fobs that cannot be decoded with a simple program. You should only attempt this method if your previous experiences are with electronic devices. It's a good idea to read your car's owner manual or search for the manufacturer on the internet, since the steps differ based on car model.
Transponder chips
Car keys with transponder chips need special programming to function. 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 be matched with the specific identification number of the vehicle or else it won't be able to start the engine.
Transponder chips, used to stop theft of cars, are a common feature of modern automobiles. The chip is a microcircuit that transmits a radio frequency signal when the key is placed in the ignition. The car is able to detect the signal, and starts the engine only if the signal is in line with the original that was programmed in the vehicle. The car also shuts down if the frequency is invalid. This makes it much harder for car thieves with no experience to connect a vehicle with hot wires and start it.
A circuit board with an induction coil connects the chip to the key. When the key is placed in the ignition, it creates a magnetic field around the transponder. This generates a signal that gets taken up by the coil, which transmits it to the key's identification number. The key's identification code is sent back to the car, and the engine starts if the identification number matches.
There are a few different methods to program a transponder keys, however, all require an instrument that is specifically designed for the purpose. You can buy these tools on the internet or at many automotive locksmiths. They're not cheap, but they're vital for programming the chip to your vehicle.
You could also use a unreprogrammable key that was programmed for another vehicle. In this case, ensure that the key has not been 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.
The process of reprogramming the transponder key is easy, but it will require specialized software and a scan tool. It's best to ask an auto locksmith for help in case you're not an expert. You should also avoid buying secondhand keys, as they are likely already programmed and will not work with your car.
