Using a Key Programmer
Modern key fobs do more than just function as keys. They communicate with the vehicle to turn it on and open the rear hatch and more. To do so they must be programmed to work together.
All automobile dealerships, auto makers and auto locksmiths provide key programming. However, you can also do it yourself, if you have the right tools.
What is a key programer?
A key programmer is a device used to recode the transponder on the fob or key of the vehicle, truck or other vehicle. This is required when a new fob or key needs to be programmed. This process is typically required when a 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 enable it to start.
Some vehicles come with electronic immobilizer systems that prevent theft by stopping the engine from starting if it is not equipped with the correct key or fob. This is done by having the car's security system verify that the key or fob has the correct digital signature. The system will shut off in the event that it doesn't. This type of system is efficient in reducing car theft and has been made compulsory for many models of car by the manufacturer.
These anti-theft systems can be controlled by a module that is installed in the vehicle's engine compartment, instrument panel, or ignition lock. In some cases the modules require specific keys that are specifically designed by a professional to function with the anti-theft system. This is usually performed by a dealership or locksmith via computers.
While it is possible to reprogramme some fobs and keys on your own however, it is not recommended unless you are a highly skilled automotive technician. A wrongly programmed key can cause the vehicle not to start, or not to run or even to be destroyed. Most auto manufacturers have a very specific procedure to program these kinds of keys.
It is advised that if you intend to offer key programming as part of your service offering, you obtain an LSID. This credential gives you access to an inventory of key and immobilizer codes along with information about the product. This access allows you to quickly and easily program and test new key for customers. It also provides essential documentation and support that will aid you in your daily business operations.
How do I program an electronic key?
Key programmer is an equipment that can help you reprogram your car's keys. It reads the information from the microchip in your key, and then write new information to the chip. This will allow you to use the key and will ensure that it is working effectively. However the procedure of using a key programmer is a bit complicated and requires some technical know-how to make use of. Therefore, before attempting to accomplish this yourself it is recommended to first consult an expert or locksmith for directions.
You can also purchase a key programmer and have it professionally programmed at a lower cost than what you would have to pay an auto shop to do the work for you. You should be aware that not all key programmer products will work with your specific vehicle. Before you purchase you must determine if the item is compatible with the model you have.
The majority of the time, you will require having your key fob reset by a dealer. This is because the key fob will need to be reprogrammed with the specific data for your vehicle's anti-theft system. Dealers typically need to have the VIN number for your vehicle in order to do this, and will typically charge a fee to do this. You can save money by giving your dealer a copy, which you'll be able to obtain from the DMV of all states.
You can also reprogram your car's key if you already have a working key. This is known as the master key method and it is applicable to certain vehicles to program an additional key. If you own an GM car, for example you can insert your key into the ignition until the security light goes out. After the security light is out, you are able to remove the working key and replace it with the new one.
You can also purchase an specialized EEPROM Key Programmer. This is a more costly but more efficient method of programming the car key. This is a more advanced technology, 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 trained automotive technicians who have extensive experience in electronic repairs.
