receiver then compares the data with the permitted signals stored in the key fob and then locks or opens the car door If the information isnt in line an chirping sound is heard and the car isnt able to operate Once the car is paired with a specific fob it will only accept signals from that device Other fobs wont work with the car even if they appear similar This helps to protect the integrity of
