Reprogramming Car Keys
Transponder keys are believed to be more secure for vehicles and more difficult to copy by thieves. The key could need to be reprogrammed in event of damage or lost.
You can program key fobs yourself however, you must be aware of the correct process. For the best results you'll need the following items:
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 the specific vehicle and its features by a licensed dealer or locksmith. They can be costly to replace in the event of loss and you should keep extras handy. You will also find replacement key fobs on various websites and in a variety of brick-and-mortar automotive shops. But how can you tell that the new key fob you bought is authentic? 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 first, you need to ensure that your vehicle is running. Insert the key you want to reprogram into the ignition without turning it. There are only a few seconds left before the system will reset all commands and leaves the programming mode. For this reason, it is essential to move fast and not wait between steps. Stop the engine to stop this. You can check the car's system by turning the key to the "on" position, then back to the "off" position. The door locks should be able to cycle, and you'll hear a chime signalling that the process was successful.
Certain vehicles of recent years use rolling keys to stop thieves from using stolen keys to open the car. The feature is still vulnerable to a technique known as replay attack. It allows thieves to record and then reproduce the signal from the car key fob to open the car. To counter this, manufacturers have added an additional security feature known as the CAN bus protocol to stop attacks on hacking.
Certain manufacturers employ a specific encryption on their keys that can't be decoded with an ordinary program. These kinds of cars will need to be programmed by a professional, and you should only attempt this process if you have experience working with electronics. It's a good idea to refer to the owner's manual of your vehicle or look up the manufacturer online, as these steps vary by car model.
Transponder chips
Car keys with transponder chips require a specific reprogramming to work. While any hardware store can cut keys for you, the biggest problem is to make it work in conjunction with your particular car. The key you reprogrammed needs to be compatible with the exact identification number of your vehicle otherwise it won't even start the engine.
Transponder chips are a standard feature of modern automobiles and are designed to guard against car theft. The chip is a microcircuit that emits a radio frequency signal when the key is placed in the ignition. The car then scans for the signal and then starts the engine in case it matches the original frequency that was programmed into the vehicle. The car will also shut down if the frequency is invalid. This makes it much harder for car thieves with no experience to wire a vehicle and then start it.
The key and the chip are connected by a circuit board that includes an induction coil. When the key is placed in the ignition it creates an electromagnetic field around the transponder. programming car keys creates a signal which is received by the coil and then transmitted to the key's identification number. The key's identification code is returned to the car and the engine is started if the identification number matches.
There are a few different methods to program a transponder key, however, all require an appropriate tool. These tools are available through the internet or from many automotive locksmiths. They are not cheap, but they are crucial for programming the chip in your car.
You may also use a unreprogrammable key that was programmed for an alternative vehicle. In this case you'll need to make sure that the key isn't damaged or that the transponder has been altered in any way. To check this, you'll need scanners or computers with a USB port to read the chip and determine its identity.
The process of reprogramming an transponder's key is simple, but it requires specialized software and a scan tool. If you're just beginning you should seek out the help of an auto locksmith. Also, avoid buying secondhand keys, as they are likely already programmed and will not work with your car.
