Using a Key Programmer
Modern key fobs go beyond simply keys; they can communicate with a vehicle to start it or open the rear hatch, and so on. To do this, they have to be programmed.
Car dealerships, your car manufacturer and auto locksmiths all offer key programming services. You can do it yourself with the right tools.
What is a key programer?
A key programmer is used to reprogram a transponder on the fob or key for a car truck or another vehicle. This process is required when the fob or key needs to be programmed. It is also often necessary when an existing fob or key is lost or stolen. The device essentially reprograms the digital signature on the chip inside the key to match the signature of the vehicle and allow it to start.
Certain vehicles come with electronic immobilizers which prevent theft by preventing the engine from being started without the right key. This is accomplished by having the car's system check to make sure that the key or fob has the correct digital signature. If it doesn't then the system will shut down. This kind of system has been proved to be effective in reducing automotive theft and has been made mandatory for various models of vehicles 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 some instances these systems require specific keys that have been designed by experts to function with the antitheft system. This is usually performed by a dealership or locksmith via a computer.
It is possible to reprogram certain fobs and keys yourself but it isn't recommended until you are an experienced automotive technician. A key that is not properly programmed could cause the vehicle to not start, or not to run or even be destroyed. The majority of auto makers have a very precise procedure for programming keys.
It is recommended that if you want to provide key programming as part of your service offering you acquire an LSID. This credential gives you access to a database of immobilizer and key codes and information about the product. This access allows you to swiftly and easily program and test a new key for customers. In addition, it gives you important support and documentation that can assist you in your day-to-day business operations.
How do I program the key?
Key programmer is an equipment that allows you to reprogram your car's keys. It reads the data from the microchip that is in your key and then write new data to the chip. This will permit you to use your key and will ensure that it functions correctly. However, the procedure of using a key programer is a bit complicated and requires some technical expertise to use. Therefore, before you attempt to do this on your own, you should first consult an expert or locksmith for guidance.
You can purchase a key programmer and get it professionally programmed online at a lower cost than what you would pay an auto dealer to complete the task for you. You should be aware that not all key programmer products are compatible with your vehicle. Before you purchase it is important to see if the product is compatible with your model.
Dealers usually have to reprogramme your key fob. The key fob has to be reprogrammed so that it can include the information specific to the anti-theft system of your vehicle. Dealers will usually need the VIN number of your car to accomplish this, and will charge a fee. You may be able to reduce the cost by providing the dealer a copy of your title which is available through the DMV in most states.
For some cars you can also try to reprogram your key if you have another working key that works with your vehicle. This method is known as the master key method, and it is applicable to certain vehicles to program the secondary key. If you own a GM vehicle, for instance you can insert your key into the ignition until the security light turns off. After the security light has gone out, you can take off the working key and replace it with the new one.
You can also buy a specialized EEPROM Key Programmer. This is more expensive but more efficient method of programming a car key. This is the most advanced technology available, which requires you to remove the car from its frame and read the information from the chip inside the key. This kind of programming should only be done by certified automotive technicians who have extensive experience in electronic repairs.
