Using programming car key do more than just act as keys. They communicate with the vehicle to get it started and open the rear hatch and more. To accomplish this, they need to be programmed together.
Car dealerships, your automobile manufacturer and auto locksmiths provide key programming services. You can do it yourself using the right equipment.
What is a key developer?
A key programmer is a device used to recode a transponder on a key or fob for an automobile or truck, or any another vehicle. This is needed when a new fob or key has to be programmed. It is also often necessary when an existing fob or key has been lost or stolen. The device basically reprograms digital signature of the chip inside the key to match the signature of the vehicle, and allows it to start.
Certain vehicles come with electronic immobilizer systems that prevent theft by stopping the engine from starting without the correct fob or key. The system checks to see whether the fob or key is digitally signed. The system will shut off if it doesn't. This kind of system has been proved to be effective in reducing automotive theft and was made mandatory for various models of vehicles by the manufacturer.
These anti-theft systems can be controlled by a device that is placed in the vehicle’s engine instrument panel, instrument panel or ignition lock. In certain instances the modules require specific keys that are specifically programmed by professionals to function with the anti-theft system. This is usually carried out by a dealer or locksmith using computers.
While it is possible to reprogramme certain fobs and keys at home, it is not recommended unless you're an experienced automotive technician. The reason is that a poorly programmed key could cause the vehicle to fail to run, not start, or even be completely destroyed. Most auto manufacturers have a specific method for programming these kinds of keys.
It is recommended that if you plan to provide key programming as part of your service, you obtain an LSID. This credential grants you access to a database of immobilizer and key codes along with product information. This access lets you quickly and easily program and test new keys for customers. In addition, it also provides you with important support and documentation that can help you with your day-to-day business operations.
How do I program an electronic key?
A key programmer can be used to reprogram the keys in your car. It will read information from the microchip on your key, and write new information onto the chip. This will permit you to use the key and will ensure it works effectively. The process of using a programmer isn't easy and requires technical knowledge. Therefore, before you attempt to complete this task on your own you should first talk to an expert or locksmith for directions.
You can also buy an online key programmer and have it professionally programmed for a much lower price than the cost to have a dealership do the job for you. However, keep in mind that not all key programmers are compatible with your vehicle and you should make sure to check the compatibility of the product with your model of car before making a purchase.
In most cases, you will need to have your key fob reset by a dealer. The key fob needs to be reprogrammed in order to include the information specific to your car's anti theft system. Dealers typically require the VIN number of your car to accomplish this, and they will charge fees. You can save money by providing your dealer a copy of the VIN, which you'll be able to obtain from the DMV of most states.
You can also reprogram your car's key if you already have a working key. This method is called the master key method, and it is applicable to certain vehicles to program a secondary key. For instance, if own a GM vehicle, you can insert your working key into the ignition and turn it on until the security light turns off. Once the security light has gone out, you can take off the working key and insert the new one.
You can also buy an specialized EEPROM Key Programmer. This is more expensive, but more effective method of programming the car key. This is a more advanced technology, which requires that you take apart the car and read the data from the chip in the key. This kind of programming should only be done by certified automotive technicians who have years of experience in electronic repairs.
