Programming Car Keys As automobiles have become more electronic, key programming has become an important service that can bring in a lot of revenue. However, many shops do not offer this service. Modern keys and fobs perform more than just starting the car. They also unlock the rear hatch and protect the vehicle from physical and virtual attacks. You need to be aware of how to program them. What is a transponder? A transponder car key has an anti-theft security feature included. This is accomplished by incorporating the radio frequency identification microchip in the plastic head portion of the key. This chip will transmit a signal to immobilizer system in your vehicle during the initial ignition process. This chip stops hot-wiring, making it difficult to take a vehicle. It isn't the case that transponder keys are a guarantee. Although they provide an additional layer of security but criminals still have the capability to use their expertise to gain entry into vehicles. It just means that it takes them longer and more effort to accomplish this which is why this security feature is an enormous benefit for anyone who cares about the security of their vehicles. The way in which transponder keys function is very straightforward. The microchip in the plastic head of the key is programmed with a specific digital serial number that correlates to the immobilizer system in your vehicle. The immobilizer system checks the serial number once you insert the key into the ignition. If it matches the serial number, the engine will begin and if not, the car will not begin. There are several types of transponder chips that can be programmed and the type that your vehicle is using will determine which type of key you own. You can locate the correct transponder chip for your car by using a search engine or going to a professional locksmith and asking them what kind of key you have. Transponder keys are more expensive to replace because of the microchip. The dealership that you use for your vehicle is the most expensive alternative for a replacement key due to the highest overhead costs, but you can also turn to an expert locksmith for your new key. Another important thing to remember is that you are able to program the transponder key if it has not been cut previously. You can do it yourself if you purchase an transponder from one the stores that provide these services. But, you'll require a specific tool to complete the task. What is the procedure for programming a transponder? A car key that has a chip in it is a kind of transponder key.

If your key has a chip the bow cover (the plastic section on the top of the key) will be heavier than on a chip-free key. You can also determine whether your keys have chips by examining the ignition. If it has a push-to start button instead of a key hole it's most likely a key that has a chip. The next step is to decide the method of programming to be used. Some transponder keys can be programmed using onboard diagnostics while others require a specialized key programming device. The key programming device must be compatible with the particular transponder or circuit board key that is being used, and it must also work at the same frequency as the car's on-board computer.
