Key fobs have to be programmed correctly. Certain keys for cars can be programmed by the owner themselves but it is best to speak with a professional. This will protect against any possible damage to the computer system, and also ensure that the new key functions correctly. How to Program a Key Most cars had basic key systems up until the turn of 21st century. Keys themselves were metal with grooves that corresponded to the internal parts of the ignition cylinder. As time passed and technology advanced, more and more automobile manufacturers began to combine physical and electronic protocols to protect against theft. These key systems are known as transponder keys or chip keys and are designed to make it difficult for thieves to get into the vehicle. The key chips contain a unique serial code that sends a message to the receiver inside your car. When the signal is received it is compared to the code that is stored in the car's computer. If the codes match the car will begin to begin to start. If the codes aren't compatible, your vehicle won't start at all. This is one of the primary reasons you should keep a spare key on your vehicle, particularly if you have transponder-based systems. If you're looking to learn how to program a key, you'll need some specific equipment. You'll need a blank key that is compatible with the model and make of your car. You can purchase them from the locksmith shop or at a car dealership, but it's crucial to purchase the correct keys. If you attempt to use a key from another model, then it won't work. Start the process by inserting the new key in the ignition and turning it "on". You'll need to keep the new key in this position for approximately 10 minutes and 30 seconds. After the time has passed you can take out your key and verify that the security indicator on your dashboard has gone out. If it did not then you'll need to do it three times. Keep in mind that this method can only work on GM vehicles, and it's still not completely secure. If you're looking for a more secure and reliable option, you should consult a professional locksmith or the dealer to get your vehicle programmed with chips. These professionals have the tools and equipment needed to access the onboard diagnostics port in your car and make the switch. Keyless Entry Systems Keyless entry systems provide property access without requiring an actual credential. Security is provided by a combination between sensors and an onboard computer. This lets you control the system and monitor activities from anywhere on the property, and does away with the requirement for keys or locks. The system can also detect stolen or lost cards and then deactivate them. The newest models also allow remote management and configuration and are cloud-based. Modern cars are equipped with keyless entry systems. To enable this feature the car emits radio signals that are picked up by a special key fob. The signals are compared with the code that is stored in the computer of the car and, if all is in order the car will start to unlock. If the signals don't match and the car does not start. If your key fob is not already programmed, it is possible to follow a series of steps to program it. First, you'll need to ensure all the doors are locked, with the exception of 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 try your local auto parts store for the right tool to program your vehicle. If these steps don't work, you'll have to go through the owner's manual or a professional locksmith. Once you have the proper tool Once you have the correct tool, you can begin changing the programming of your key fob by following the instructions of the manufacturer. This procedure is usually quick and simple. For instance, you may be directed to insert your new key into the ignition while keeping all doors shut and then press the button on the key fob within a brief time. The car may then respond by turning off the door locks or generating a chime to signal that the key was successfully programmed. Many locksmiths have special tools that permit them to bypass the built-in EEPROM security on the car's key fob or remote. But, this is an extremely risky procedure and comes with the possibility of destroying the data stored on your car's computer. It is best to let an expert handle this task, as they will be able to reduce the chance of data corruption and ensure your keys are properly programmed. Transponder Keys Transponder keys are also referred as chip keys. They feature an embedded microchip in the head of keys. When the key is inserted into the barrel of the ignition lock and then turned into the ON position the antenna ring transmits an electromagnetic energy blast through the transponder chip. This energy is absorbed by the chip and it transmits the radio frequency signal, which includes an identification code that corresponds up to the unique digital serial number in the car's computer system. This will prevent any unauthorized attempts to start the car since only the right key will be able to perform the task. This technology is thought to be more secure than a traditional car key since it makes it difficult for a criminal to "hot wire" the vehicle and then start it. But it's not foolproof, and thieves have found ways to deceive and defy the system - so that even vehicles with transponder keys aren't immune from theft. Based on the make and model of your vehicle You may be capable of programming a new transponder key yourself using a key programmer that's compatible with your particular car. The key programmer will come with a user guide that walks you step-bystep through the process. Once you have your key and a key programmer, follow the steps carefully and ensure the security light on your dashboard is on prior to turning your engine on. You can ask an expert locksmith to assist you if you are not confident using the key programmer or you have a car with more advanced features, such as remote head keys or intelligent keys. They will have the tools and equipment needed to cut blank keys, erase the old one from the computer in the car, and then program the new key to function properly. This will save you money and time and ensure that your car's safety system functioning exactly as it should. Plus, it is much safer than doing it yourself. Making use of the wrong key programmers or following unofficial guides can corrupt the information in the vehicle's system and result in your new key not functioning. Remotes If your car keys don't work, you might need to change the programming. It's a straightforward process for most modern cars that have key fobs. However, some models are more complex and require programming using an instrument that is available from the dealer or auto locksmiths. To decrease the risk of theft from vehicles Modern car makers have enhanced the security of their key systems. The key system was designed to stop hot-wiring, which is using a key from a different vehicle to start the engine of your vehicle. To ensure that this method works you'll need at least two key fobs that are functioning for your vehicle. This is one of the reasons why it's best to have at least one spare key on hand. The keys have electronic chips in them that communicate with the car's radio via radio signals. The computer compares the key's code with the database. If the codes are the same the car will be able to start. If the codes do not match then the car will not start or will remain dead. Fortunately, the majority of electronic keys can be repaired and programmed by an experienced locksmith or an auto dealer using the appropriate equipment.
