Using a Key Programmer
Modern key fobs aren't just keys; they communicate with vehicles to start it, open the rear hatch, and so on. To do this, they have to 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 programer?
A key programmer is used to reprogram a transponder on a key or fob for a car, truck or another vehicle. This process is required when a new fob or key must be programmed. It's also common in cases where an existing fob or key is lost or stolen. The device basically reprograms the digital signature on the chip inside the key to match the signature of the vehicle, and allows it to start.
Some vehicles have electronic immobilizer systems that stop theft by preventing the engine from starting if it is not equipped with the correct fob or key. This is accomplished by having the car's system examine to ensure that the key or fob has the correct digital signature. The system will shut down if it doesn't. This kind of system has been proved to be effective in reducing the incidence of theft and is now required for a variety of models of cars by the manufacturer.
Most of these anti-theft systems are controlled by a module that is 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 work with the anti-theft system. This is typically done by a dealer or locksmith who uses computers.
It is possible to reprogram certain keys and fobs yourself, but it is not recommended until you're an experienced automotive technician. This is because a wrongly programmed key can cause the vehicle to run, not start or even be destroyed. The majority of auto makers have a particular procedure for programming these types of keys.
If you're looking 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 database of key and immobilizer codes along with product information. With this access, you are able to program and test new keys for customers quickly and easily. It also provides important documentation and support that can aid you in your day-to-day business operations.
How do I program an electronic key?
A key programmer can be used to modify the keys of your car. It reads data from the microchip in your key, and then write new information onto the chip. This will allow you to use the key, and make sure that it functions properly. The procedure of programming a key isn't easy and requires technical knowledge. Before you attempt to program the key yourself, consult a professional locksmith or expert for advice.
You can also purchase a key programer online and get it professionally programmed at less than you would pay to have a dealership complete the work for you. It is important to know 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.
Most of the time you'll need to have your key fob reprogrammed by an dealer. This is because the key fob will need to be reprogrammed with the specific information required by your vehicle's anti-theft system. A dealer will typically require the VIN number for your car to do this, and typically charge a fee for this. You can save money by providing your dealer a copy of the VIN, which you'll be able to obtain from the DMV of 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 is a method to program a second key on certain vehicles. For example, if you own a GM vehicle, you can insert your working key into the ignition and switch it on until the security light turns off. Once the security light goes out, you can remove the working key and then insert the new one.
You can also buy an specialized EEPROM key programmer which is a costlier but more effective method of programming a car key. However this is a more advanced technology that requires dismantling the car and reading the information from the microchip inside the key. This kind of programming is best suited to professional automotive technicians who have extensive experience in electronic repair.
