Using car key programming fobs aren't simply keys; they can communicate with vehicles to start it and open the rear hatch, and much more. To do so, they need to be programmed to work together.
All car dealerships, auto manufacturers and auto locksmiths can provide key programming. You can also do it yourself, if you have the right equipment.
What is a key developer?
A key programmer is a device used to recode the transponder in a key or fob for a car or truck, or any another vehicle. This is needed when a new fob or key has to be programmed. It's also common when an existing fob or key has been stolen or lost. The device essentially reprograms the digital signature of the chip inside the key to match the signature of the vehicle and allow it to begin.
Some vehicles are equipped with electronic immobilizers that stop theft by preventing the engine from starting without the proper key. This is done by having the car's system verify that the key or fob has the right 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 various models of automobile by the manufacturer.
The anti-theft system can be controlled by a module installed in the vehicle’s engine instrument panel, instrument panel, or ignition lock. In some cases they require keys that have been specifically programmed by an expert to function with the anti-theft system. This is typically performed by a dealership or locksmith through the use of a computer.
While it is possible to reprogramme certain keys and fobs by yourself, it is not recommended unless you're an skilled automotive technician. A wrongly programmed key can cause the vehicle to not begin, stop running or even be destroyed. The majority of auto makers have a very specific procedure to program these kinds of keys.
If you're looking to include key programming into your offerings it is recommended you obtain an LSID (Locksmith Service ID). This credential grants you access to a secure database of product information as well as keys and immobilizer codes via the NASTF's Secure Data Release Model. This access permits you to program and test new keys for customers quickly and easily. It also provides important documentation and support to help you with your day-to-day business operations.
How do I program my key?
A key programmer can be used to reprogram the keys of your car. It reads information from the microchip inside the key, and write new information onto the chip. This allows you to use the key, and ensure that it functions correctly. The process of using a programmer can be a bit complicated and requires technical expertise. Therefore, before you attempt to do this on your own it is recommended to first consult an expert or locksmith for guidance.
You can also buy a key programmer online and get it professionally programmed at a much lower price than you would pay to have a dealership do the work for you. It is important to know that not all key programmers products will work with your car. Before you purchase, you should check to see if the product is compatible with the model you have.
Dealers will usually need to reprogram your key fob. The key fob must be reprogrammed so that it can include the specific information for the anti-theft system of your vehicle. Dealers typically need to have the VIN number for your vehicle to perform this and they typically charge a fee for it. You might be able to reduce the cost by providing the dealer a copy your title which is available through the DMV in the majority of states.
For certain vehicles you can also try to reprogram your own key if you have another working key that is compatible with your vehicle. This is called a master key method and can be used to program a second key on some vehicles. If you own a GM car, for example put your key in the ignition until the security light goes off. Once that happens you can take out the working key and insert the new one to program it.
You can also purchase a specialized EEPROM Key Programmer. This is more expensive, but more efficient method of programming a car key. This is a more advanced technology, which requires that you take apart the car and read the information from the chip inside the key. This type of programming is best suited to professionals in the field of automotive mechanics who have extensive experience in electronic repair.
