How to Program a Car Key Modern cars come with more than just a key that will start the engine. They also have a remote control which can be used to lock or open doors. These key fobs must be programmed to function. It is possible to program some car keys by the owner, however it is best to consult an expert. This will protect against any possible damage to the car's computer system and also ensure that the new key is working correctly. How do you program the key Before the turn of the 21st century the majority of cars had basic key systems. The keys were made of metal and had grooves to correspond to the internal parts in the ignition cylinder. As time went on and technology advanced and improved, car manufacturers began blending physical and electronic protocols to prevent theft. These key systems are known as transponder keys or chip keys and are designed to make it more difficult for thieves to open the vehicle. The key chips in the keys have a unique serial number that transmits signals to the receiver inside of your car. The signal is compared with a code in the computer of the car when it is received. If the codes match then your car will begin. If the codes aren't compatible, your car will not even start. This is one of the primary reasons to keep a spare key for your vehicle, especially when you use an electronic transponder. You'll require special equipment to learn to program keys. You'll also need a blank key for your specific model and make. You can buy them at the locksmith shop or at a car dealership, but it's important to buy the right one. If you use a key that is for another model, it won't work. Start by inserting the new key into the ignition and turning it "on". It is necessary to leave the new key in this position for approximately 10 minutes and 30 second. After the time has passed, you can remove your key and see if the security indicator on your dashboard has gone out. If not then you'll need repeat the process a third time. This method is only compatible with GM vehicles and isn't completely secure. If you're looking for a safer and reliable method, you should seek out a professional locksmith or dealer to have your car programmed with a chip. These professionals have the necessary tools and equipment to access the onboard diagnostic port of your car and then make the change. Keyless Entry Systems Keyless entry systems allow property access without requiring a physical credential. Security is provided by sensors that are combined with an onboard computing device. This allows you to control the system and monitor activities from anywhere on your property, and it removes the requirement for keys or locks. The system can also detect and disable stolen or lost cards. In addition, the latest models are cloud-based and permit remote management and configuration. The majority of modern cars are equipped with a keyless entry system. To accomplish this, the vehicle emits radio signals that are picked up by a special key fob. The signals are compared with the code stored in the car's computer and, if all is well the car will start to unlock. The car won't start in the event that the signals are not the same. There are a variety of steps you can take to program your new key fob if it's not programmed yet. First, you'll need to make sure that all doors are locked, except for the driver's side.

This is best left to a professional, who can reduce the risk of data corruption and make sure that your keys are correctly programmed. Transponder Keys Transponder keys, sometimes referred to as chip keys, are equipped with an embedded microchip in the head of the key. When the key is inserted into the barrel of the ignition lock, and turned to ON the antenna ring emits an electromagnetic energy blast through the transponder chip. This energy is absorbed by the chip, which then transmits an audio frequency signal that contains an identification code that corresponds up to the unique serial number in the car's computer system. This prevents any attempts by anyone else to start the car since only right keys can be used. 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" an automobile and start it. But it's not foolproof, and thieves have found ways to evade and thwart the system so that even cars that have transponder keys aren't immune from theft. Depending 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 particular car. The key programmer will come with an instruction manual that will walk you through the procedure of programming your key.
