transponder as the correct signal it will not start the engine and will notify you via flashing lights and an alarm This feature is designed to deter people from trying to hack into the vehicle

the middle of the key This communication is encrypted which helps prevent others from intercepting and retransmitting the signal Keyfobs can be programmed in different ways based on the model and make of your car Some cars allow you to do it yourself However the majority of newer models require you to visit a professional locksmith or dealer to program a replacement key fob or additional one When you press a key fobs button it transmits an encoded code to the cars radio that it is linked to The receiver compares the information with the allowed signals that are stored on the key fob and then opens or locks the cars doors If the information isnt in line a chirping sound is heard and the car isnt permitted to operate Once the car is associated with a particular fob it will only accept signals from that device As a result other fobs wont work with the vehicle even if they appear similar This safeguards the integrity of the computer system in the vehicle and stops the use of unauthorized key fobs to gain control of it The majority of newer dealerships will only work with cars that have original fobs or genuine replacements offered by the manufacturer The reason for this is that the only place that has the expertise to prepare the replacement fob is a dealers service department Some fobs from the aftermarket especially those for older models with less advanced systems can be programmed without the need for a dealer
