Reprogramming Car Keys
Transponders in car keys are believed to make vehicles safer and are less likely to be duplicated by thieves. However, keys may require reprogramming when it becomes damaged or lost.
You can program key fobs yourself but you must be aware of the correct process. You should have these items to get the most effective results:
Keys
The majority of modern vehicles require a transponder keys to operate. This is a security feature and protection against theft. The keys have to be programmed to your specific vehicle and its features by an authorized dealer or locksmith. They can be costly to replace if they are lost and you should keep extras handy. You can find replacement key fobs in online stores and many brick and mortar auto shops. How can you know that the one you purchased is authentic? Are you able to tell whether it was programmed for a different vehicle or if it is able to be reprogrammed to fit your vehicle?
If you're looking to program an entirely new key the first step is to ensure that your vehicle is operating. Insert the key you want to program into the ignition, but don't turn it. You will only have just a few seconds before the car's system resets the commands and then exits programming mode. It is important that you be quick and don't delay between each step. Turn off the engine to stop this. You can test 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 sound that indicates that the procedure was successful.
programming car key use a rolling key technology, which prevents thieves from using stolen cars' key to start it. The technology is still susceptible to a technique dubbed replay attack, which allows thieves to record the signal of the key fob on the vehicle, then reproduce it to open the car. To counter this, manufacturers have added a security feature called the CAN bus protocol to prevent hacking attempts.
Certain manufacturers employ a specific encryption on their keys, which cannot be decoded using a simple program. These types 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 is a good idea to consult the owner's manual of your vehicle or search for the manufacturer on the internet, since the steps will differ depending on the vehicle model.
Transponder chips
Transponder chip car keys require a specific reprogramming to work. Any hardware store can make you an entirely new car key, but the real challenge lies in integrating it with your car. A reprogrammed key will need to be compatible with the exact identification number of your car otherwise it won't even start the engine.
Transponder chips are a typical feature of modern cars and are designed to stop car theft. The chip is a small microcircuit which transmits a radio-frequency signal when the ignition key is placed. The car then detects the signal and begins the engine if it matches the original signal that was programmed into the vehicle. The vehicle is also programmed to shut down when it detects an incompatible frequency. This makes it difficult for thieves who aren't experienced to wire a vehicle hot and then start it.
A circuit board with an induction coil connects the chip to the key. When the key is placed in the ignition the magnetic field is generated around the transponder. This generates a signal, which is absorbed by the coil and then transmitted to the key identification number. The key's identification number is sent back to the car and the engine is started when the identification number is in line with.
There are several ways to program a transponder, however all of them require the use of a specific tool. These tools can be purchased through the internet or from many automotive locksmiths. These tools are not expensive, but they are essential to program your car's chip.
You can also use an resettable key that was programmed for an alternative vehicle. In this scenario, ensure that the key has not been damaged or that the transponder is not altered in any way. To accomplish this, you'll need a scanner or a computer equipped with a USB port to read the chip and determine its identity.
Reprogramming a transponder is a simple procedure, but requires specialized software. It also requires a scanner tool. It's best to ask an auto locksmith for help for those who are new to the process. Avoid buying used keys as they might already be programmed, and they won't be compatible with your vehicle.
