How to Program a Car Key Modern cars come with more than just a key which starts the engine. They also come with a remote that allows you to lock or unlock doors. These key fobs need to be programmed correctly. It is possible to program certain car keys by the owner, however it is best to consult an expert. This will protect against any possible damage to the computer system and also ensure that the new key is working properly. How do you program a key? Most cars had basic key systems until the turn of 21st century. Keys themselves were metal with grooves that corresponded to the internal components of the ignition cylinder. As time went on and technology improved as it did, automobile manufacturers began to combine electronic and physical protocols to protect against theft. These key systems are called transponder keys or chip keys and they're designed to make it more difficult for thieves to get into the vehicle. The key chips in the keys have a unique serial number, which transmits signals to the receiver inside your car. When the signal is received, it compares it to an existing code in the car's computer. If the codes are identical, your car will begin to start. If the codes don't match, then your car won't even start. This is one of the primary reasons you should keep a spare key in your car, especially in the case of a transponder-based system. You'll need special equipment to learn how to program keys. You'll also require a blank key that matches your specific model and make. These can be purchased at an auto dealership or from a locksmith however, you must be sure they're the correct ones. If you use a key that is for another model, it will not work. Start by inserting the new key into the ignition and turning it to "on". It is necessary to leave the new key in this position for about 10 minutes and 30 second. Once the time is up you can take off the key and observe if the security light on your dashboard was gone. If it didn't go out then you'll need to repeat the procedure three times. Be aware that this method will only work on GM vehicles however it isn't completely secure. If you want a more secure and reliable option, you can visit an auto locksmith or dealer to get your car programmed with an embedded chip. They are equipped with the tools and equipment required to connect to the onboard diagnostic port on your vehicle and make the necessary changes. Keyless Entry Systems Keyless entry systems allow access to property without the requirement of a physical credential. They make use of sensors in conjunction with an onboard computer for security. This lets you manage the system and monitor its activity from any location on your property, and it removes the requirement for locks or keys. The system can also detect stolen or lost cards and disable them. The most recent models also permit remote management and configuration, and are cloud-based. Most modern cars come equipped with a keyless entry system. The system works by emitting radio signals which are received by the keyfob. These signals are then compared with the correct code stored in the car's system, and if everything is in order, the car will unlock. The car won't start when the signals aren't the same. If your key fob isn't already programmed, you may follow a few steps to program it. First, you'll need to make sure that all doors excluding the driver's door are locked.

Transponder Keys Transponder keys, also known as chip keys, come with an embedded microchip in the head of the key. When the key is placed in the barrel of the ignition lock, and turned to the ON position the antenna ring transmits an electromagnetic energy blast through the transponder chip. The chip absorbs this energy, and then transmits a radiofrequency signal that includes an identification code. This code matches the unique digital serial numbers of the computer system of the car. This is to prevent any attempts by anyone else to start the car since only proper keys will be able to do so. This technology is believed to be more secure than traditional keys for cars because it makes it much harder for a thief to "hot wire" the vehicle and start it. But it's not foolproof and thieves have discovered ways to deceive and thwart the system so that even cars with transponder keys aren't safe from theft. Based on the make and model of your vehicle, you may be in a position to program a brand new transponder key yourself by using a key programming device that's compatible with your specific car.

The key system is designed to prevent hot-wiring, which is the practice of using a key from another vehicle to start the engine of your vehicle. Therefore, you'll need at least two functioning key fobs for your vehicle in order to be able to use the system. It's important to have two spare keys in your possession. The keys have electronic chips in them which communicate with the car's receiver via radio signals. The car's computer then compares the code on the key to the one in its database. If the codes are the same the car will begin. If not, the car will not start or fail to start. Luckily, most of these electronic keys can be programmed and replaced by a professional locksmith or auto dealer with the right equipment. If you can find a cheap car key programmer online or at an auto parts store, the procedure will be relatively simple.
