Using a Key Programmer
Modern key fobs are more than simply function as keys. They communicate with the vehicle to get it started, open the rear hatch and more. To accomplish this, they need to be programmed to work with each other.
Car dealerships, your vehicle manufacturer and auto locksmiths all offer key programming services. But you can also do it yourself if you have the right equipment.
What is a key programer?
A key programmer is a device used to recode the transponder in a car or truck key or fob. This process is required when a new fob or key needs to be programmed. It's also common when an existing fob or key is lost or stolen. The device basically reprograms digital signature on the chip inside the key to match that of the vehicle and allow it to start.
Certain cars are equipped with electronic immobilizers that stop theft by stopping the engine from running without the right key. This is done by having the car's system check to make sure that the fob or key has the correct digital signature. If it does not, the system will shut down. This kind of system is very effective in reducing car theft and was made mandatory for various models of automobile by the manufacturer.
Most of these anti-theft systems are controlled by a module that is installed in the engine compartment instrument cluster, instrument cluster, or ignition lock. In some instances, these modules require special keys that are specifically designed by a professional to work with the anti-theft system. This is usually carried out by a dealer or locksmith using computers.
It is possible to reprogram certain keys and fobs yourself, but it is not recommended until you are an experienced technician for automotive. This is because the wrong programmed key could cause the vehicle to start, run, or even be completely destroyed. Most auto manufacturers have a particular procedure for programming these kinds of keys.
If you're looking to include key programming into your service offerings it is recommended you get an LSID (Locksmith Service ID). This credential gives you access to an encrypted database of information about the product and keys and immobilizer codes via the NASTF's Secure Data Release Model. This access lets you quickly and easily program and test a new key for customers. Additionally, it gives you important assistance and documentation to aid you in your day-today business operations.
How do I program an electronic key?
Key programmer devices can be used to reprogram the keys in your car. It reads data from the microchip inside the key, and write new information to the chip. This will allow you use the key, and ensure that it is functioning properly. However the process of using a key programming device can be a bit difficult and requires some technical expertise to use. Before you attempt to do this yourself, you must consult a professional locksmith or professional for guidance.
You can also purchase a key programmer and have it professionally programmed online at a cost that is lower than the cost you would pay an auto shop to do the job for you. But, remember that not all key programmers are compatible with your vehicle and you must ensure the product's compatibility with the model of your car prior to purchasing.
The majority of the time you'll need to have your key fob reprogrammed by a dealer. The key fob must 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 of your vehicle in order to do this and they typically charge a fee for it. You might be able to save money by giving the dealer a copy your title, which you can obtain through the DMV in most states.
You can also change the programming of your key on some cars when you already have a working key. This is called a master key method and it can be used to program a different key on some vehicles. For instance, if are driving a GM vehicle, you can insert your working key into the ignition and switch it on until the security light turns off. Once this happens you can take out your working key and then insert the new one to program it.
You can also buy an exclusive EEPROM Key Programmer. This is a more costly but more efficient method of programming a car key. This is the most advanced technology available, which requires that you remove the car from its frame and read the information from the chip inside the key. This kind of programming should only be carried out by certified automotive technicians who have extensive experience in electronic repairs.
