Using a Key Programmer

Modern key fobs aren't just keys. They communicate with a vehicle to start it or open the rear hatch, and more. To do so, they need to be programmed to work in conjunction.

Car dealerships, your automobile manufacturer and auto locksmiths all provide key programming services. You can do it yourself with the right equipment.

What is a key programmer?

Key programmer is a device that allows you to reprogram the transponder on the car or truck fob or key. This process is necessary when a new key or fob has to be programmed. This process is often required when a fob or a key is lost or stolen. The device essentially reprograms the digital signature of the chip inside the key to match that of the vehicle and enable it to begin.

Some vehicles have electronic immobilizers that protect against theft by stopping the engine from starting if it is not equipped with the correct fob or key. The system checks to see if the key or fob is digitally signed. The system will turn off if it doesn't. This type of system is efficient in reducing theft of automobiles, and was made mandatory 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 or instrument panel, or ignition lock. In some cases they require keys that are specifically programmed by an expert to function with the anti-theft system. This is typically performed by a dealership or locksmith via computers.

While it is possible to reprogramme some keys and fobs at home, it is not recommended unless you're a highly skilled automotive technician. This is because the wrong programmed key can cause the vehicle to run, not start or be destroyed. Most auto manufacturers have a very specific 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 grants you access to a database of immobilizer and key codes and product information. This access permits you to program and test new keys for customers quickly and easily. It also provides essential documentation and support that can assist you in your day-to-day business operations.

How do I program the key?

A key programmer is a piece of equipment that allows you to reprogram your car's keys. It reads information from the microchip on your key, and write new information onto the chip. This will permit you to use the key and will ensure that it functions properly. However the process of using a key programer is a bit complicated and requires some technical know-how to utilize. Before you attempt to program the key yourself, you should seek out a locksmith expert for advice.

You can also purchase a key programmer online and get it professionally programmed at less than the cost to have a dealership complete the job for you. But, remember that not all key programmers are compatible with your vehicle. You must confirm the compatibility of the product with your model of car before making a purchase.

Most of the time, you will require having your key fob reprogrammed by a dealer. This is because the key fob will need to be reprogrammed with the specific information required by your vehicle's anti-theft system. Dealers will usually require the VIN number of your vehicle to perform this, and usually charge a fee for this. You can save money by giving your dealer a copy, which you'll be capable of obtaining from the DMV of all states.

For certain vehicles, you can also try to reprogram your own key if you already have a working key that is compatible with your vehicle. This is referred to as master key method, and can be used to program a second key on certain vehicles. If you own an GM car, for example you can insert your key into the ignition until the security light goes off. Once that happens then you can remove the working key and insert the new one to program it.

You can also buy a specially designed EEPROM key programmer which is a more expensive, but more efficient way to program car keys. However this is a more advanced technology that requires dismantling the car key reprogramming and reading the information from the microchip within the key. This type of programming is best for professionals in the field of automotive mechanics who have vast experience in electronic repair.
