Key fobs must be programmed to work properly. It is possible to pre-program certain keys for cars by the owner, however it is best to consult an expert. This will help protect against any possible damage to the computer system and ensure that the new key functions correctly. How to program the key Most cars had basic key systems prior to the turn of 21st century. Keys themselves were metal and had grooves that matched the internal parts of the ignition cylinder. As technology advanced the number of car manufacturers began to combine electronic and physical protocols to stop theft. Key systems like these, also known as transponder keys or chips keys, are designed to make it harder for thieves to start a vehicle. The key chips that are in the keys have a unique serial number that sends a signal to the receiver inside your car. The signal is compared to a code in the computer of the car when it is received. If the codes match, the car will start. If the codes aren't compatible, your vehicle won't start at all. This is one of the primary reasons to keep a spare key for your car, especially in the case of an electronic transponder. You'll require specialized equipment to learn to program keys. You'll also need a blank key for your particular model and make. They can be purchased from the dealership or through a locksmith but you must make sure that they are the correct ones. If you use a key from another model, it won't function. To start the process, you need to 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 approximately 10 minutes and 30 seconds. When the time has passed, you can remove the key and check if the security light on your dashboard was gone. If not, you'll need to repeat the process for another time. This method is only compatible with GM vehicles and it's not completely secure. If you're seeking a more secure and reliable method, you should consult a professional locksmith or dealer to get your vehicle programmed with a chip. These professionals are equipped with the tools and equipment required to access the onboard diagnostic port on your car and perform the change. Keyless Entry Systems Keyless entry systems allow property access without requiring a physical credential. Security is offered by the combination of sensors and an onboard computer. It is possible to monitor and control the system from anywhere within the property. Keys and locks are not required. The system can also detect and disable stolen or lost cards. In addition, the newest models are cloud-based, allowing for remote management and configuration. Modern automobiles are equipped with keyless entry systems. To accomplish this, the vehicle emits radio signals that are picked up by a specific key fob. The signals are then compared to the code stored in the car's computer, and if all is well the car will be able to unlock. If the signals don't match, the car will not start. There are several ways to program your new key fob if it's not programmed yet. You'll first need to be sure that all doors except the driver's door are locked. You'll need the original key fob along with any other devices you wish to program. You can also check the local auto parts store to determine if they carry the appropriate tool for your vehicle.

However this is a risky method and comes with the possibility of destroying the data on the computer in your car. This should be left to a professional who can lower the chance of data corruption and ensure that your keys are correctly programmed. Transponder Keys Transponder keys, also known as chip keys, are equipped with an embedded microchip in the head of the key. The antenna ring transmits electromagnetic energy to the transponder whenever the key is placed into the barrel of the ignition lock. The energy is absorbed by the chip, which then transmits the radio frequency signal, which includes an identification code that corresponds with the unique serial number in the car's computer system. This will prevent any an unauthorized attempt to start the car since only the right key can do so. It is believed that this technology will be more secure than traditional car keys because it makes it more difficult for thieves to "hot wire" a vehicle and get it started. But it's not foolproof and thieves have discovered ways to evade and defy the system - which means that even cars equipped with transponder keys are not safe from theft. You might be able to program a transponder key on your own when you have an instrument that works with your car. The key programmer comes with a manual that will take you step-by-step through the procedure. Once you have the key and a key programmer, follow the instructions carefully and ensure the security light on your dashboard is turned ON prior to turning the engine ON.
