However, as time progressed and technology improved, more and more automobile manufacturers began blending physical and electronic protocols to protect against theft. Key systems, also known as transponder keys or chips keys are designed to make it harder for thieves to start a vehicle.

The key chips inside the keys have a specific serial number, which transmits signals to the receiver inside your car. When the signal is received, it compares it to the code that is stored in the car's computer. If the codes are compatible, then your car will start. If the codes aren't compatible, your car will not even start. This is the reason you should keep an extra car key especially if the system is transponder-based.

These professionals have the tools and equipment needed to connect to the diagnostic port on your vehicle and make the change.

Keyless Entry Systems

Keyless entry systems grant property access without the need for an actual credential. They use sensors in combination with an onboard computer to offer security. This lets you control the system and monitor its activity from anywhere on your property, and does away with the requirement for locks or keys. The system can also identify and block stolen or lost cards. 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 that are detected by a special key fob. These signals are then compared against the correct code in the car's computer, and if everything is in order the car will start to unlock. The car will not start in the event that the signals are not the same. There are several steps you can follow to program your new key fob if it isn't already programmed.

Transponder Keys

Transponder keys are also referred to as chip keys. They feature embedded microchips in the head of keys. The antenna ring transmits electromagnetic energy to the transponder key programmer when the key is put into the barrel of the ignition lock. The chip absorbs this energy and then transmits a radio frequency signal that includes an identification code. The code is matched to the unique serial numbers of the computer system of the car. This prevents unauthorised attempts 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 difficult for thieves to "hot wire" a vehicle and get it started. However, it's not foolproof and thieves have found ways to deceive and defeat the system - so that even vehicles that have transponder keys aren't immune from theft.
