What is a transponder-key?
A transponder car key features a security feature against theft built in. This is achieved by integrating a microchip for radio frequency identification into the head of the key. This chip is used to transmit a signal to immobilizer system of your vehicle during the ignition startup process. This chip stops hot-wiring and makes it very difficult to steal the vehicle.
This is not to say that transponder keys are infallible however, even though they add an additional layer of security, it does not mean that criminals is unable to use their skill set to break into the vehicle. It just means that it takes them much more time and effort to accomplish this, which is why this security feature is a huge benefit to anyone who is concerned about the security of their vehicles.
The way that the transponder key functions is very simple. The microchip that is embedded in the head of the key is programmed with a unique serial number that is connected to the immobilizer system that is in your vehicle. When you put the key in the ignition, the immobilizer system will detect the serial number and validate it. If the serial number is in line, then the engine will start.
There are a few different kinds of transponder chips that can be programmed and the type your vehicle is using will determine the type of key you have. You can locate the correct transponder chip to match your vehicle through an online search engine or by visiting a professional locksmith and asking them to tell you 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 option for getting a replacement key due to the most expensive overhead costs, however you can also turn to a professional locksmith to get your new key.
Another thing to keep in mind is that you are able to program the transponder key only if it has not been cut previously. You can do it yourself if purchase the transponder from one of the stores that offer these services. However, you'll require a specific tool to complete the task.
What is the procedure for programming the transponder?
Transponder keys are keys for cars equipped with a chip. They are designed to prevent theft of vehicles by ensuring that only the correct key is able to start the vehicle. Locksmiths can create a new key for you in the event that you've lost yours, or the chip is damaged in some way. In most cases, the process for programming a chip key is relatively simple and straightforward. Certain cars require special equipment to program the key.
The first step in the process is to determine what kind of key you have. To ensure that you have the correct key blank, it is important to know your vehicle's make, model and year. Some keys have a transponder in the head of the key, while others do not. If your key has a chip the bow cover (the part of the plastic that is on the top of the key) will be more thick than on a non-chip key. It is also possible to determine if your key has a chip by looking at your ignition. If it has a push-to start button instead of a key hole, it is probably an ignition equipped with chip.
Once you have the appropriate blank for the key, the next step is to decide the method of programming to be employed. Certain transponder keys can be programmed using on-board diagnostics, while others require a specific key programming device. The device used to program keys must be compatible with the circuitboard/key transponder that is being used. It must also operate at the same frequency of the computer on board of the vehicle.
It's tempting to save money by programming a transponder yourself, but this can be risky. If you don't follow the proper steps, you may corrupt the information on the chip and make it impossible to start your car. It is best to get your key programmed by someone who has the tools and expertise necessary to do so. It is a good idea, while you have the keys, to create additional keys to replace them quickly and easily if you lose one.
How do I program my transponder key?
The chip must be programmed inside the head of the car key if your vehicle is controlled by transponders. This procedure can be difficult particularly in the event that your keys are lost or damaged. In some cases it is possible to start the vehicle without the transponder chip, however, this is not recommended and could cause issues. In these situations you should consult an experienced locksmith or car dealer to resolve the issue.
You need the right tools to program a transponder. Also, you need to know the right procedure. Transponder keys usually have an antenna ring on the head that transmits radio frequency energy to a chip inside. The chip then responds with an identification code to the antenna ring. When the signal is received, the ignition system can detect that the key has been placed in the key and then activate.
You can do this at home if you have the appropriate equipment and knowledge of the process for your particular vehicle. Many manufacturers have a particular programming method that may require certain supplies. It is important to know that programming requires the use of a long-lasting battery. If your battery dies during the process, you'll have to begin the process over again from the beginning.
This is the reason why many prefer having an expert do it for them. Transponder keys that are properly programmed can save you time and money.
Follow car key programming to program a new key to work with an older one. You should use the transponder key programer that is compatible with the vehicle model you have. Follow the instructions on the device to get the best results. Some car models use special technology that requires a dealer to design a key. This is not the case with the majority of cars. The process should be easy and fast if you have the correct key and necessary equipment.
