Using a Key Programmer

Modern key fobs do more than simply function as keys. They communicate with the vehicle to turn it on, open the rear hatch, and more. To do this, they have to be programmed.

All automotive dealerships, auto manufacturers and auto locksmiths provide key programming. But you can also do it yourself, if you have the right tools.

What is a key programmer?

A key programmer is used to reprogram a transponder on the fob or key of an automobile, truck or another vehicle. This procedure is necessary when a new fob or key needs to be programmed. This process is typically required when a key or fob key programmer is stolen or lost. The device essentially reprograms the digital signature on the chip inside the key to match that of the vehicle and allow it to start.

Certain cars are equipped with electronic immobilizers which prevent theft by stopping the engine from being started without the right key. The system checks to determine whether the fob or key is digitally signed. If it does not it will shut down. This kind of system has been proven to be effective in reducing the incidence of theft and has been made mandatory for various models of vehicles by the manufacturer.

Most anti-theft systems are controlled by a module that is installed in the vehicle's engine, instrument cluster, or ignition lock. In certain instances the modules require special keys that are programmed by experts to work with the anti-theft system. This is usually done by a dealer or locksmith who uses computer.

While it is possible to reprogramme certain fobs and keys on your own but it is not advised unless you're a highly skilled automotive technician. The wrongly programmed key could cause the vehicle to not start, fail to run or even be destroyed. Most auto manufacturers have a specific method for programming these types of keys.

This credential allows you access to a database of key and immobilizer codes, as well as details about the product. This access lets you quickly and easily program and test new key for customers. In addition, it also provides you with important support and documentation that can assist you in your day-to-day business operations.

Dealers typically need to have the VIN number for your car to do this, and usually charge a fee for this. You can save money by providing your dealer a copy which you are capable of obtaining from the DMV of the majority of states.

For example, if you are driving a GM vehicle, you can insert your working key into the ignition and switch it on until the security light goes off. Once this happens you can take out your working key and then insert the new one to program it.

You can also purchase a specialized EEPROM key programmer which is a more expensive but more effective method of programming a car key.
