Using a Key Programmer
Modern key fobs 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 must be programmed.
All automobile dealerships, auto makers and auto locksmiths can provide key programming. You can do it yourself using the right tools.
What is a key programmer?
Key programmer is a device used to recode the transponder in the car or truck key or fob. This process is required when a new fob or key needs to be programmed. This process is typically required when a key or fob is lost or stolen. The device basically reprograms the digital signature of the chip inside the key to match that of the vehicle and enable it to start.
Some vehicles have electronic immobilizer systems that stop theft by stopping the engine from starting without the correct key or fob. This is accomplished by having the car's system check to make sure that the fob or key has the correct digital signature. The system will shut down when it isn't. This kind of system has been found to be effective in reducing the incidence of theft and was made mandatory for a variety of models of cars by the manufacturer.
These systems can be controlled by a module that is installed in the vehicle's engine compartment, instrument panel or ignition lock. In certain instances, these modules require special keys that are specifically programmed by professionals to work with the anti-theft system. This is usually done by a dealer or locksmith using a computer.
Although it is possible to reprogramme some fobs and keys by yourself, it is not recommended unless you're a highly experienced automotive technician. A wrongly programmed key can cause the vehicle to not start, fail to run or even break. Most auto manufacturers have a specific method to program these kinds of keys.
It is advised that if you intend to offer key programming as a part of your service offerings you get an LSID. This credential grants you access to the database of immobilizer and key codes, as well as information about the product. With this access, you are able to create and test new keys for customers quickly and effortlessly. Additionally, it provides you with important assistance and documentation to aid you in your day-today business operations.
How do I program an electronic key?
A key programmer can be used to modify the keys of your car. It will read information from the microchip in the key, and write new information onto the chip. This will allow you to use the key and ensure that it is functioning correctly. The procedure of programming a key can be a bit complicated and requires technical knowledge. So, before you try to accomplish this on your own it is recommended to first consult an expert or locksmith for directions.
You can purchase an electronic key programer and get it professionally programmed online at a lower cost than what you would have to pay an auto shop to do the job for you. Be aware that not all key programmers products will work with your specific vehicle. Before making a purchase, you should check to determine if the item is compatible with the model you have.
In most cases, you will require having your key fob reset by a dealer. The key fob needs to be reprogrammed so that it can include the specific information for your car's anti-theft system. A dealer will typically need to have the VIN number for your vehicle to perform this, and typically charge a fee for it. You can save money by giving your dealer a copy of the VIN, which you will be in a position to get from the DMV of most states.
You can also reprogram your car's key in the event that you already have a functioning key. This method is called the master key method and it can be applied to certain vehicles in order to program a secondary key. For instance, if you have an GM vehicle, simply insert your working key into the ignition and turn it on until the security light turns off. Once this happens, you can remove your working key and then insert the new one to program it.
You can also buy an specialized EEPROM key programmer, which is a costlier but more effective method to program car keys. However it is a more advanced technology that requires removing the car and reading the data from the microchip in the key. This type of programming should only be done by trained automotive technicians who have extensive experience in electronic repairs.
