How to Program a Car Key Modern cars have more than just a key to start the engine. They also have a remote that can lock and unlock doors. These key fobs must be programmed in order to function. It is possible to program certain keys for cars by the owner, however it is recommended to speak with a professional. This will prevent any damage to the computer system of the car and ensure that the key functions properly. How to Program a Key The majority of cars had basic keys systems up until the turn of 21st century. The keys themselves were metal and featured grooves that were connected to the internal components of the ignition cylinder. As time passed and technology improved, more and more automobile manufacturers began to combine electronic and physical protocols to stop theft. These key systems are called transponder keys or chip keys, and are designed to make it harder for thieves to open the vehicle. The key chips have unique serial codes that transmits a message to the receiver inside your car. When the signal is received it compares it with a code stored in the car's computer. If the codes are similar, your car will start. If the codes don't match, then your car will not even start. This is why it is important to keep an extra car key especially if the system is transponder-based. You'll require special equipment to be able to program keys. You'll need a blank key that matches your car model and make. These can be purchased at a dealership or by a locksmith however, you must be sure they're the correct ones.

It is necessary to keep the key in this position for approximately 10 minutes and 30 seconds. Once the time is up you can take off the key and check whether the security indicator on your dashboard went out. If it didn't you'll have to do it three times. This method is only compatible with GM vehicles, and isn't foolproof. If you want a more secure and reliable option, you can visit a locksmith or dealer to have the car programmed using an embedded chip. These professionals have the necessary tools and equipment needed to access your car's onboard diagnostics port and make the change. Keyless Entry Systems Keyless entry systems allow property access without requiring an actual credential. They use sensors in conjunction with an onboard computer to provide security.

The most recent models also permit remote management and configuration and are cloud-based. Most modern cars come equipped with the keyless entry system. To accomplish this it emits radio signals which are picked up by a particular key fob. The signals are compared with the code that is stored in the car's computer and if everything is well, the car will unlock. If the signals do not match then the car won't start. If your key fob is not already programmed, it is possible to follow a series of steps to programme it. You'll first need to be sure that all doors excluding the driver's door are locked.

This is best left to a professional who can lower the chance of data corruption and make sure that your keys are properly programmed. Transponder Keys Transponder keys, also referred to as chip keys, have a microchip embedded in the head of the key. The antenna ring transmits electromagnetic energy to the transponder when the key is put in the barrel of the ignition lock. The chip absorbs the energy and then sends a radio frequency signal which contains an identification number. The code is matched to the unique digital serial numbers of the car's computers. This prevents unauthorized attempts to begin the car as only the right keys can be used. This type of technology is thought to be more secure than a conventional car key because it makes it harder for a thief "hot wire" the vehicle and then start it. However, it's not foolproof and thieves have discovered ways to deceive and defy the system - so that even vehicles with transponder keys are not safe from theft. Based on the make and model of your car depending on the make and model of your car, you might be in a position to program a brand new transponder key by yourself with a key programer that is compatible with the car you own.

The car's computer then compares this key's code to the one stored in its database. If the codes match the car will be able to start. If the codes do not match, the car will not start or will remain dead.
