How to Program a Car Key Modern cars come with more than a key that starts the engine. They also come with a remote control which can be used to lock or unlock doors. Key fobs must be programmed correctly. Certain keys for cars can be programmed by the owner, however it is recommended to consult a professional. This will prevent any possible damage to the car's computer system, and also ensure that the new key functions correctly. How do you program a key? The majority of cars had basic key systems until the turn of 21st century. Keys were made from metal and featured grooves that match the internal components in the ignition cylinder. As cut and program car key passed and technology improved as it did, car manufacturers began blending physical and electronic protocols to protect against theft. Key systems like these, also known as transponder keys or chips keys are designed to make it harder for thieves to steal the vehicle. The key chips contain a unique serial code which transmits a signal to the receiver inside your car. The signal is then compared to a code in the computer of the car when it is received. If the codes match, your car will start. If not, it won't start at all. This is the reason you should keep a spare car key, particularly if your system is based on transponders. You'll need special equipment to be able to program keys. You'll also need an uncut key for your specific model and make. You can purchase these at the locksmith shop or at a car dealership, but it's important to purchase the correct keys. If you try to use a key that is from an alternative model, it won't work. To begin the process, insert the new key into the ignition and turn it to the “on” position. You'll need to keep the key in this position for around 10 minutes and 30 seconds. After the time is up you can take out your key and see if the security indicator on your dashboard has gone off. If not, you'll need to do it again for the third time. This method is only compatible with GM vehicles and isn't 100% secure. If you're looking for a more secure and reliable solution then you should visit an auto locksmith or dealer to have the car programmed using an embedded chip. They are equipped with the tools and equipment required to access the onboard diagnostics port of your car and make the switch. Keyless Entry Systems Keyless entry systems allow access to properties without the requirement for an actual credential. Security is achieved through sensors that are combined with an onboard computing device. It is possible to manage and monitor the system from anywhere within the property. Keys and locks are not required. The system can also identify stolen or lost cards and then deactivate them. The newest models also allow remote management and configuration and are cloud-based. The majority of modern cars are equipped with the keyless entry system. This system works by emitting radio signals which are received by a special keyfob. The signals are compared with the code stored in the computer of the car and, if all is in order the car will start to unlock. If the signals do not match then the car won't start. If your key fob isn't already programmed, it is possible to follow a few steps to program it. The first step is to make sure that all doors are locked except for the driver's side. You'll need to have the original key fob along with any other devices you wish to program. You can also visit the local auto parts store to see if they've got the appropriate tool for your car. If none of these methods work, you will have to consult the owner's manual or a professional locksmith. Once you have the correct tool Once you have the correct tool, you can begin changing the programming of your key fob by following the manufacturer's instructions. The process is usually fast and simple. For instance, you could be instructed to insert your new key into the ignition with all doors closed and then press the button on the key fob within a brief time frame. The car could then respond by adjusting the door locks or emitting a sound to signal that the key has been successfully programmed. A lot of locksmiths have tools that allow them to bypass the built-in EEPROM security in your car's key fob or remote. This is a risky technique and can cause corruption of the data stored in the car's computer. It is best to let an expert handle this, as they will be able to minimize the risk of data corruption and make sure that your keys are programmed correctly. Transponder Keys Transponder keys are also referred as chip key. They have a microchip embedded inside the head of the keys. When the key is placed in the ignition lock barrel and turned to ON the antenna ring transmits an energy burst through the transponder chip. The chip absorbs this energy, and then transmits a radiofrequency signal which contains an identification number. The code is matched to the unique serial numbers of the computer system of the car. This prevents unauthorised attempts to start the car, since only the right key will be able to perform the task. This technology is believed to be more secure than traditional keys for cars because it makes it much more difficult for thieves to “hot wire” the vehicle and start it. It's not foolproof and thieves have found ways of tricking and defeating the system. So even cars with transponder keys aren't immune to theft. Based on the make and model of your car You may be in a position to program a brand new transponder key yourself using a key programmer that's compatible with your specific car. The key programmer will come with a user guide that will guide you step-by-step through the process. Once you have your key and a key programmer, follow the instructions carefully and ensure that the security light on your dashboard is on prior to turning your engine ON. If you're uncomfortable programming keys, or if your car comes with more advanced features, such as remote head keys or smart keys, you can go to a professional locksmith for assistance. They'll have the right tools and equipment to cut the blank key, remove your previous one from the computer in the car and then program the new key to ensure that it works properly. This will save you time and money and will keep your car's safety system functioning just as it should. Plus, it is much safer than making it yourself. If you use a incorrect key programming software or follow unofficial guides or instructions, the information stored in your car's computer could be corrupted, and the new key won't work. Remotes You may have to reprogramme your car keys if they aren't working. This is an easy process for many modern vehicles that have key fobs. However, some models are more complicated and need to be programmed with the aid of a special device that's usually available from the dealer or auto locksmiths. To decrease the risk of theft from vehicles, modern car manufacturers have increased the security of their key systems. The key system was designed to avoid hot-wiring (the practice of using another vehicle's key to start the engine) and other similar methods. To make this process work, you will need at least two key fobs functioning for your vehicle. This is just one of the reasons why it's recommended to have at least one spare key in your possession. The keys have electronic chips in them that communicate with the car's receiver via radio signals. The computer examines the key's code with the database. If the codes are the same the car will be able to start. If the codes don't match then the car will not start or remain dead. Fortunately, the majority of electronic keys can be programmed and replaced by an expert locksmith or an auto dealer with the right equipment. If you can find an inexpensive car key programmer on the internet or at an auto parts store, the procedure will be relatively simple. You'll need to follow a particular sequence of steps that includes inserting the key into the ignition, turning it on, without starting the engine, then turning the key off. You'll need to repeat this a certain number of times within a specified time period to allow your vehicle to enter programming mode. The door locks will turn on and off or chime. Certain modern vehicles are only capable of being programmed using a tool that is connected to the onboard diagnostic port or EEPROM programming. These tools are costly and therefore unaffordable by most car owners. The majority of car experts recommend consulting with a reputable auto dealership or locksmiths to program your keys.
