Reprogramming Car Keys
Transponder keys are believed to be more secure for vehicles and more difficult to copy by thieves. A key may have to be reprogrammed in event of damage or lost.
You can program key fobs yourself but you must be aware of the proper procedure. You should have these items to ensure the best results:
Keys
Most modern vehicles require a transponder fob or transponder keys to work, which provides security and anti-theft protection. The keys are programmed by a locksmith or an authorized dealer to function with your car's system and specific model. They can be costly to replace if lost therefore, you should have spares in your car. You can find replacement key fobs in online stores, as well as many brick-and mortar auto shops. How can you be sure that the one you bought is authentic? Do you know whether the unit is programmed to work with a different vehicle, or if it can be programmed differently?
If you are planning to program an entirely new key, the first step is to ensure that your vehicle is running. Insert the key you wish to reprogram into the ignition, but do not turn it. You will only have a few seconds before the car's system resets the commands and leaves programming mode. Therefore, it is important to move fast and not be able to wait between steps. Stop the engine to avoid this. Turn the key from "on" to "off" to test the system. The door locks should cycle, and you'll hear a sound that indicates that the process has been successful.
Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to open the car. This feature is still vulnerable to a technique called a replay attack. It allows thieves to record and later reproduce the signal from the vehicle key fob to open the car. To stop this, manufacturers introduced a security feature known as the CAN bus protocols to ward off hacking.
Some manufacturers also use special encryption on their key fobs, which are not decoded by an ordinary program. These types of cars will need to be programmed by a professional. Therefore, you should only attempt this process if you have experience working with electronics. Check the manual of your car or visit the website of the manufacturer for information on how to program it. The steps to follow will differ depending on the model of vehicle.
Transponder chips
Transponder chip car keys require a special 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 must be programmed to match the exact identification number on your car, or else it will not start.
Transponder chips are a typical feature of modern cars and are designed to guard against car theft. The chip is a microcircuit which transmits a radio-frequency signal when the ignition key is put in. The car is able to detect the signal and starts the engine only if the signal matches the one programmed into the vehicle. The car will also shut down if the frequency is invalid. This makes it much more difficult for novice car thieves to wire a vehicle and then start it.
The chip and the key are linked by the circuit board which includes an induction coil. When the key is placed in the ignition, a magnetic field is generated around the transponder. This produces a signal which gets absorbed by the coil, which sends it to the key's identification number. The key's identification number is then transmitted back to the car and the engine will start when the identification number matches.
There are several methods to program a transponder key however, all require an appropriate tool. These tools can be purchased online or from most automotive locksmiths. These tools aren't inexpensive, but they are vital for programming the chip in your car.
You may also use a resettable key that was programmed for a different vehicle. In this case, make sure the key hasn't been damaged or that the transponder is not altered in any way. To accomplish this, you can use scanners or computers equipped with an USB port to read the chip and determine its identity.
The process of reprogramming the transponder key is simple, but it requires an expertly designed software and scan tool. If you're new to the process it is recommended to seek help from an auto locksmith. Avoid buying used keys because they may already be programmed and won't work with your vehicle.
EZ Installer
For a long time, owners of cars who needed to replace their key fob had no other option than to go to an auto dealer to have their key electronically paired to the vehicle. It is because to make modern keys work they have to be "paired". This required expensive and complicated equipment that was available only to dealers. The EZ Installer by Car Keys Express simplifies the process of pairing up modern keys to vehicles for retailers and locksmiths.
