As time passed and technology advanced, more and more automobile manufacturers began blending electronic and physical protocols to prevent theft. These key systems are called transponder keys or chip keys and are designed to make it difficult for thieves to start the vehicle.

The key chips come with a unique serial code that sends a message to the receiver inside your car. When the signal is received it compares it with an existing code in the car's computer. If the codes match the programmable car keys will begin to begin. If the codes don't match, then your car will not even start.

The majority of modern cars are equipped with a keyless entry system. This system works by emitting radio signals that are picked up using the keyfob. The signals are compared to the code stored in the car's computer and if everything is well the car will be able to unlock. If the signals don't match then the car won't start. There are a variety of ways to program your new key fob, if it isn't already programmed.

The energy is absorbed by the chip and sends back a radio frequency signal with an identification code that matches with the unique digital serial number in the car's computer system. This helps prevent unauthorized attempts to start the car, because only a valid key will be able to do so.

This technology is thought to be more secure than a traditional car key, as it makes it harder for a thief "hot wire" the vehicle and start it.

Key fobs are equipped with electronic chips which communicate with the car's receiver using radio signals. The computer in the car then compares the key's code to the one in its database. If the codes match, the car will start. If the codes do not match the car won't start or will remain dead. Fortunately, the majority of electronic keys can be replaced and programmed by a professional locksmith or auto dealer with the right equipment.
