Using a Key Programmer

Modern key fobs go beyond simply keys; they can communicate with vehicles to start it and open the rear hatch, and so on. To accomplish this, they need to be programmed to work together.

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

What is a key programmer?

A key programmer is a device used to change the transponder code in a car or truck key or fob. This process is required when the fob or key has to be programmed. It's also common in the event that an existing fob or key is stolen or lost. The device basically reprograms digital signature on the chip inside the key to match that of the vehicle, and allows it to start.

Certain cars are equipped with electronic immobilizers which prevent theft by stopping the engine from starting without the right key. This is accomplished by having the car's system verify that the key or fob has the right digital signature. If it doesn't, the system will shut down. This type of system has been found to be effective in reducing the incidence of theft and was made mandatory for many models of cars by the manufacturer.

These systems can be controlled by a module installed in the vehicle's engine or instrument panel, or ignition lock. In some instances the modules require specific keys that have been specifically programmed by an expert to function with the anti-theft system. This is typically carried out by a dealer or locksmith using a computer.

It is possible to reprogramme certain fobs and keys yourself but it isn't recommended until you're an experienced technician in the field. This is because the wrong programmed key could cause the vehicle to fail to start, run, or even be completely destroyed. The majority of auto makers have a very specific procedure for programming these types of keys.

If you're looking to include key programming in your service offerings it is recommended you get an LSID (Locksmith Service ID). This credential gives you access to the database of key and immobilizer codes and product information. With this access, you are able to create and test new keys for customers quickly and effortlessly. In addition, it also gives you important assistance and documentation to aid you in your day-today business operations.

How do I program the key?

This allows you to use the key and ensure that it functions properly. However the procedure of using a key programer can be a bit difficult and requires some technical know-how much to programme a car key to make use of. Before you attempt to do this yourself, seek out a locksmith expert for advice.

For some cars you can also try to reprogram your key if you have a second working key that works with your car. This is referred to as a master key method and can be used to program a second key on certain vehicles. If you have a GM car, for example, insert your key into the ignition until the security light goes out. After the security light is out, you are able to remove the working key and replace it with the new one.

You can also purchase a specially designed EEPROM key programmer, which is a more expensive but more effective method to program a car key. However it is a more advanced technology that requires taking the car apart and reading the information from the microchip within the key.
