How to program a key

The majority of cars had basic keys systems until the turn of the 21st century. The keys were made of metal and featured grooves that correspond with 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, also known as transponder keys or chips keys, are designed to make it more difficult for thieves to steal the vehicle.

The key chips that are in the keys have a specific serial number that sends an electronic signal to the receiver in your car. When the signal is received, it compares it to the code that is stored in the car's computer. If the codes match, then your car will start. If not, it won't start at all. This is why you should keep an extra car key especially if the system is based on transponders.

If you're looking to learn how to program keys, you'll need some special equipment. You'll also require an uncut key for your particular model and make.

The signals are then compared to the code that is stored in the car's computer and if everything is in order the car will start to unlock. The car won't start if the signals are not identical. If your key fob isn't already programmed, you may follow a few steps to program it.

The antenna ring transmits electromagnetic energy to the transponder whenever the key is put in the barrel of the ignition lock. This energy is absorbed into the chip and it transmits a radio frequency signal with an identification code that is matched with the unique serial number that is stored in the car's computer system. This will prevent any an unauthorized attempt to start the car, because only a valid key can start the car.

This technology is believed to be more secure than traditional keys for cars because it makes it much difficult for thieves to "hot wire" a vehicle and start it. It's not foolproof and thieves have discovered ways of tricking and defeating the system. So even cars equipped with transponder keys aren't safe from theft.

If the codes don't match then the car will not start or remain dead. Luckily, most of these electronic keys can be repaired and programmed by a professional auto dealer or a locksmith with the right equipment.
