How to Program a Car Key Modern cars use more than just a single key to start the engine, they also come with a remote that can lock and unlock doors. These key fobs have to be programmed to function. Some keys for cars can be preprogrammed by the owner, however it is best to speak with a professional. This will prevent any damage to the computer system of the vehicle and ensure that the key is working properly. How do you program a key Most cars had basic key systems until the turn of 21st century. Keys were made from metal and had grooves to correspond with the internal parts in the ignition cylinder. As time passed and technology advanced, more and more automobile manufacturers began blending physical and electronic protocols to stop theft. These key systems are called transponder keys or chip keys, and they're designed to make it harder for thieves to start the vehicle. The key chips come with a unique serial code that transmits a message to the receiver in your car. The signal is then compared to an identifier in the car's computer when it is received. If the codes match, then the car will start. If not, it won't start at all. This is why it is important to keep an extra car key especially if your system is transponder-based. If you want to learn how to program a key, you'll need some special equipment. You'll need to buy a blank key that is compatible with your car model and make. You can purchase them from the locksmith shop or at a car dealership, but it's essential to purchase the correct keys. If you attempt to use a key that is from another model, then it will not work. To begin the process, simply insert the new key into the ignition and switch it to the “on” position. It is necessary to keep the key in this position for around 10 minutes and 30 seconds. After the time has passed you can take out your key and check if the security indicator on your dashboard has gone off. If not then you'll need to repeat the process for the third time. Be aware that this method will only work on GM vehicles, and it's still not completely secure. If you're looking for a more secure and reliable method, you should consult a professional locksmith or dealer to have your car programmed with a chip. They will have the tools and equipment to connect to your car's onboard diagnostics port and then make the change. Keyless Entry Systems Keyless entry systems allow property access without requiring the use of a physical ID. Security is offered by the combination of sensors and an onboard computing device. This allows you to control the system and monitor activities from any location within the property, and does away with the need for keys or locks. The system can also detect and deactivate lost or stolen cards. The most recent models also permit remote management and configuration and are cloud-based. Most modern cars come equipped with the keyless entry system. To accomplish this, the vehicle emits radio signals which are picked up by a particular key fob. The signals are compared to the code that is stored in the computer of the car and, if all is well the car will be able to unlock. If the signals do not match, the car will not start. There are a variety of steps you can follow to program your new key fob, if it's not programmed yet. First, you'll need ensure that all doors are locked, except for the driver's side. Also, you'll need the original key fob, as well as any extras you'd like to program. You can also check your local auto parts store to see if they have the right tool for your car. If none of these methods work, you'll have to consult the owner's manual or an expert locksmith. Once you've got the proper tool, follow the manufacturer's instructions to begin reprogramming your key fob. The process is usually quick and easy. You might be told to put the new key in the ignition while all doors are closed and then press the button on the keyfob within a specific time. The car may respond by reversing the doors or emitting an audible chime, which is a sign that the key has been successfully programmed. Many locksmiths employ special tools to get around the EEPROM security features that are built into the remote of your car or key fob. This is a dangerous method and could cause data corruption stored in the car's computer. This is best left to a professional, who can minimize the risk of data corruption and make sure that your keys are properly programmed. Transponder Keys Transponder keys are also known as chip keys. They have an embedded microchip in the head of the keys. When the key is placed in the barrel of the ignition lock and then turned to the ON position, the antenna ring sends an energy burst through the transponder chip. The chip absorbs the energy and then transmits a radiofrequency signal that contains an identification code. This code matches the unique serial numbers in the computer of the car. This will prevent any an unauthorized attempt to start the car, since only the right key will be able to perform the task. The technology is believed to be more secure than the traditional car key, as it makes it more difficult for a thief “hot wire” the vehicle and start it. It's not foolproof and thieves have found ways to evade detection and defeat the system. So even cars with transponder key are not protected from theft. You might be able to program a transponder key by yourself if you have an instrument that works with your vehicle. The key programmer should come with an instruction manual that will guide you through the process of programming your key. Once you have the key and a key programmer, follow the steps carefully and ensure that the security light on your dashboard is turned on prior to turning your engine ON. If you're not comfortable using a key programmer, or if your car includes more advanced features such as remote head keys or smart keys, you can go to a professional locksmith assistance. They'll have the appropriate tools and equipment to cut your blank key, delete your previous one from the car's computer, and then program the new key to ensure that it works properly. This will save you time and money and will help keep your car's security system functioning exactly as it should. It is also safer than making it yourself. Making use of the wrong key programmers or following unofficial guidelines could corrupt the information in the vehicle's system and result in your new key not working. Remotes If your car keys aren't working you may need to change the programming. This is an easy process for many modern cars that utilize key fobs. However, certain models are more complex and require programming with the help of an additional device that's typically available from a auto locksmith or dealer. To prevent theft of vehicles Modern car manufacturers have enhanced the security of their key systems. The key system is designed to stop hot-wiring, which is the practice of using a key from another vehicle to start the engine of your vehicle. To be reprogram car key to make this process work, you will need at least two key fobs that are working for your vehicle. It is essential to have at least two spare keys available. The key fobs have electronic chips that communicate via radio signals to the car's receiver. The computer compares the key's code with the database. If the codes match the car will begin. If the codes don't match, the car will not start or remain dead. Luckily, most of these electronic keys can be replaced and programmed by an expert locksmith or an auto dealer with the right equipment. The procedure should be fairly simple if you are able to find a low-cost key programmer on the internet or in an auto parts store. You'll need to follow a set of instructions that include inserting the ignition key and turning it on, without starting the vehicle, and then switching off the key. You will need to repeat the steps a specified number of times within the timeframe you specify to put your vehicle in programming mode. This will be indicated by the door locks cycling or a chime that sounds audible.
