This adds an extra layer of security, decreasing the risk of thefts and other vehicle-related crimes.

You should also check whether there is any equipment installed between the antenna and the receiver, like a surge protector or splitter, because this could impact the strength of the signal. If the EEPROM programming method is used to program a new car key, it involves extracting specific components from your car (security components) and reading the "password" and other stored information from them. This requires a lot of knowledge, as there is a possibility that the information can be corrupted.

Faulty Electronics Many modern cars have security systems that block them from starting the engine in the event that they don't have a car key or remote.
