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 with each other.
Car dealerships, your automobile manufacturer and auto locksmiths all offer key programming services. You can do it yourself using the right tools.
What is a key programmer?
A key programmer is a device used to recode the transponder in a key or fob for a car truck or other vehicle. This process is required when a new fob or key must be programmed. It is also necessary in cases where an existing fob or key is lost or stolen. The device basically reprograms digital signature of the chip inside the key to match the signature of the vehicle and allow it to start.
Certain cars are equipped with electronic immobilizers that prevent theft by stopping the engine from being started without the proper key. The system checks to determine whether the fob or key is digitally signed. If it does not, the system will shut down. This kind of system is effective in reducing automobile theft, and was made mandatory for many models of car by the manufacturer.
Most of these anti-theft systems are controlled by a module installed in the vehicle's engine or instrument cluster or ignition lock. In some instances, these modules need special keys that have been designed by experts to function with the antitheft system. This is usually done by a dealership or locksmith via a computer.
Although it is possible to reprogram some fobs and keys by yourself but it is not advised unless you are a highly skilled technician in the field of automotive. A wrongly programmed key can cause the vehicle to not start, fail to run or even break. Most auto manufacturers have a very specific procedure to program these kinds of keys.
If you want to add key programming to your offerings, it is recommended that you get an LSID (Locksmith Service ID). This credential gives you access to a secure database of product information as well as key and immobilizer codes through the NASTF's Secure Data Release Model. This allows you to swiftly and easily program and test a new key for customers. It also provides crucial documentation and support to aid you in your everyday business operations.
How do I program an electronic key?
A key programmer is an equipment that allows you to modify the keys in your car. It reads the data from the microchip that is in your key and write new data to the chip. This will permit you to use the key and ensure that it is working correctly. However the procedure of using a key programming device can be somewhat complicated and requires some technical know-how to make use of. Before you attempt to program the key yourself, you should consult a professional locksmith or expert for advice.
You can also purchase a key programer online and get it professionally programmed for a much lower price than what you would pay to have a dealership do the job for you. You should be aware that not all key programmers products are compatible with your vehicle. Before you purchase you must make sure that the product is compatible with the model you have.
Most of the time you'll need to have your key fob reprogrammed by a dealer. This is because the key fob needs to be programmed with the specific information required by your vehicle's anti-theft system. A dealer will typically need to have the VIN number of your car to do this and they typically charge a fee for it. You can save money by giving your dealer a copy which you'll be capable of obtaining from the DMV of the majority of states.
For certain cars you can also try to program your own key if you have a second working key that works on your car. This method is known as the master key method, and it is applicable to certain vehicles to program a secondary key. If you own an GM vehicle, for instance, insert your key into the ignition until the security light goes out. Once this happens then you can remove 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 effective method of programming the car key. This is an advanced technology which requires that you remove the car from its frame and read the data from the chip inside the key. This kind of programming should only be done by professional automotive technicians with vast experience in electronic repairs.
