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. Key fobs must be programmed correctly. Some keys for cars can be programmed by the owner himself, but it is best to speak with a professional. This will help to protect against any possible damage to the computer system and ensure that the new key works correctly. How to Program a Key The majority of cars had basic key systems until the turn of the 21st century. Keys were made from metal and incorporated grooves to correspond to the internal parts of the ignition cylinder. As technology improved the number of car manufacturers began to combine electronic and physical protocols in order to prevent theft. These key systems are known as transponder keys or chip keys, and they're designed to make it more difficult for thieves to get into the vehicle. The key chips contain unique serial codes that transmits a message to the receiver inside your car. When the signal is received it compares it with an existing code in the car's computer. If the codes match, then your car will begin to start. If not, it won't start at all. This is why you should keep a spare car key, especially if your system is based on transponders. If you're interested in learning how to program keys, you'll need some specific equipment. You'll also need to purchase an uncut key that matches your specific model and make. They can be purchased from the dealership or through locksmiths however, you must be sure that they are the correct ones. If you attempt to use a key that is from another brand, it will not work. To start the process, you need to insert the new key into the ignition and turn it to the "on" position. It is necessary to leave the new key in this position for around 10 minutes and 30 second. When the time has passed you can take out the key and see if the security light on your dashboard was gone. If it didn't, you'll need to repeat the process for the third time. This method is only compatible with GM vehicles and isn't foolproof. If you want 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 have the tools and equipment required to connect to the onboard diagnostic port on your car and perform the change. Keyless Entry Systems Keyless entry systems provide property access without requiring a physical credential. They use sensors in combination with an onboard computer to offer security. This lets you manage the system and monitor activity from anywhere on your property, and it eliminates the requirement for keys or locks. The system is also able to detect and disable stolen or lost cards. In addition, the latest models are cloud-based, allowing for remote management and configuration. Most modern cars come equipped with an entry system that is keyless. To enable this feature, the vehicle emits radio signals which are picked up by a specific key fob. These signals are then compared against the correct code stored in the car's computer, and if everything is in order the car will be able to unlock. If the signals don't match and the car does not start. If your key fob has not been already programmed, it is possible to follow several steps to program it. You'll first need to be sure that all doors excluding the driver's door are locked. You'll need the original key fob along with any extras that you want to program. You can also visit your local auto parts shop to see if they've got the right tool for your car. If these steps don't work, you will have to consult the owner's manual or an expert locksmith. Once you have the proper tool, you can begin the reprogramming of your key fob following the instructions of the manufacturer. The process is usually fast and easy. For instance, you may be directed to insert your new key into the ignition with the doors shut, and then press a button on the key fob within a very short time. The car might 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 let them bypass the built-in EEPROM security of the key fob of your car or remote. This is a risky technique and could cause data corruption on your car's computer. This is best left to a professional who can lower the chance of data corrupting and ensure that your keys are properly programmed. Transponder Keys Transponder keys are also referred as chip key. They have an embedded microchip in the head of keys. When the key is placed in the ignition lock barrel and turned into the ON position the antenna ring transmits an energy burst through the transponder chip. The chip absorbs this energy, and then sends a radio frequency signal which contains an identification number. The code is matched to the unique serial numbers in the computer of the car. This prevents unauthorised attempts to start the car as only the correct key can start the car. It is believed that this technology will be more secure than conventional car keys because it makes it more difficult for thieves to "hot wire" an automobile and start it. But it's not foolproof, and thieves have found ways to deceive and defy the system - so that even cars with transponder keys are not protected from theft. Based on the make and model of your car depending on the make and model of your car, you might be able to program a new transponder by yourself by using a key programming device that's compatible with the car you own. The key programmer will come with an instruction manual that will walk you through the process of programming your key. Once you have the key and key programmer, follow the directions carefully and make sure the security light on your dashboard is ON before turning your engine on. If you're uncomfortable programming keys or if your car includes more advanced features such as remote head keys or smart keys, you may turn to a professional locksmith assistance. They'll have the appropriate tools and equipment to cut your blank key, delete your old one from the computer in the car, and then program the new one so that it will work properly. This will save you money and time and ensure that your car's safety system operating just as it should. Additionally, it's much safer than making it yourself. If you use a wrong key programmer or follow unofficial instructions, the information in your car's system can be corrupted and the new key will not function.

However, some models are more complicated and require programming using an additional device that's typically available from the dealer or auto locksmith. Fortunately, most modern car manufacturers have improved their key systems to be more secure to reduce vehicle thefts. The key system was designed to prevent hot-wiring (the method of using the key of another vehicle to start the engine) and other similar methods. To be able to make this process work you'll require at least two key fobs that are functioning for your vehicle. It's important to have at least two spare keys in your possession. The keys have electronic chips in them which communicate with the car's receiver via radio signals. The computer in the car then compares the key's code with the one in its database. If the codes are the same, the car will start. If the codes do not match the car won't start or remain dead.
