Using a Key Programmer

Modern key fobs are more than just keys. They communicate with vehicles to start it, open the rear hatch, and much more. To accomplish this, they need to be programmed to work with each other.

All automobile dealerships, auto makers and auto locksmiths provide key programming. But you can also do it yourself, if you have the right equipment.

What is a key programer?

A key programmer is used to recode the transponder key programmer in the fob or key for a car truck or another vehicle. This is needed when a new fob or key needs to be programmed. It's also common in cases where an existing key or fob has been stolen or lost. The device basically reprograms the digital signature on the chip inside the key to match the signature of the vehicle and enable it to start.

Some vehicles have electronic immobilizer systems that stop theft by preventing the engine from running without the correct key or fob. This is done by having the car's system check to make sure that the fob or key has the right digital signature. If it doesn't it will shut down. This type of system is effective in reducing automobile theft, and was made mandatory for many models of car by the manufacturer.

The majority of these anti-theft systems are controlled by a module installed in the vehicle's engine instrument cluster, instrument cluster, or ignition lock. In some instances, these modules require special keys that have been specifically created by a professional to function with the anti-theft system. This is usually done by a dealer or locksmith with computer.

Although it is possible to reprogramme certain fobs and keys by yourself but it is not advised unless you are a highly experienced automotive technician. The wrongly programmed key could cause the vehicle to not begin, stop running or even break. The majority of auto manufacturers have a precise process to program these keys.

It is recommended that if you want to offer key programming as a part of your service you acquire an LSID. This credential gives you access to a database of immobilizer and key codes, as well as information about the product. With this access, you are able to program a car key and test new keys for customers quickly and easily. In addition, it also offers you support and documentation that can help you with your day-to-day business operations.

How do I program an electronic key?

A key programmer can be used to reprogram the keys of your car. It reads information from the microchip on your key, and add new information to the chip. This allows you to use the key and ensure that it functions properly. The process of using a programmer isn't easy and requires technical expertise. Before you attempt to do this yourself, seek the advice of a professional locksmith expert for advice.

You can also buy a key programmer online and have it professionally programmed at a much lower price than the cost to have a dealer do the work for you. You should be aware that not all key programming products will work with your specific vehicle. Before purchasing a product it is important to make sure that the product is compatible with the model you have.

Dealers usually have to reprogram your key fob. The key fob needs to be reprogrammed so that it can include the specific information for your car's anti theft system. Dealers typically require the VIN number of your car to accomplish this, and they charge a fee. You can save money by giving your dealer a copy which you will be able to obtain from the DMV of the majority of states.

For certain vehicles you may also be able to reprogram your own key if you have a second working key that works with your vehicle. This is called a master key method and it is a method to program a second key for certain vehicles. For instance, if are driving a GM vehicle, insert your working key into the ignition and turn it on until the security light goes off. When the security light goes out, you can remove the working key and replace it with the new one.

You can also purchase an specialized EEPROM Key Programmer. This is a more costly but more efficient method of programming a car key. However it is a more advanced technology that requires taking the car apart and reading the data from the microchip inside the key. This kind of programming should only be done by professional automotive technicians with vast experience in electronic repairs.
