This will prevent any possible damage to the computer system and also ensure that the new key works properly. How do you program the key The majority of cars had basic key systems until the turn of 21st century. Keys were made of metal and had grooves to correspond with the internal parts in the ignition cylinder. As technology improved the number of car makers began to mix electronic and physical protocols in order to prevent theft. Key systems like these are also referred to as transponder keys or chips keys are designed to make it harder for thieves to open a vehicle. The key chips inside the keys have a specific serial number that sends an electronic signal to the receiver in your car. The signal is then compared to an identifier in the computer of the car when it is received. If the codes are compatible, then 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 on your vehicle, particularly when you use a transponder-based system. You'll require special equipment to learn to program keys. You'll need a blank key that matches the model and make of your car. They can be purchased from a dealership or by locksmiths however, you must be sure that they are the correct ones. If you attempt to use a key from an alternative model, it won't work.

This energy is absorbed by the chip and sends back a radio frequency signal with an identification code that is matched with the unique serial number in the car's computer system. This prevents any attempts by anyone else to start the car, as only proper keys will be able to 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” the vehicle and start it.
