If the system recognizes the signal, it triggers to open the doors of the vehicle and also activate the computer onboard. Some systems include an additional receiver in the car's trunk that opens it automatically when you put your foot under it.
Each key fob comes with an individual digital identity code that's issued by the manufacturer. A unique process of technology known as "programming" is used to configure the fob with a specific car's system. This involves turning on the ignition of the vehicle several times in a specific sequence, and could require pushing or pulling levers or buttons or even removing the fuse.
When a key fob is programmed to your vehicle's keyless entry system it transmits its digital identity code, along with a function code that instructs the car what to do (lock in, unlock, or open the trunk). The receiver in the car verifies that the transmitter is the person it claims to be using an authentication and encryption process. The onboard computer will unlock the vehicle and start the engine when it is authorized.
A skilled criminal could snoop and use the code sent between the keyfob and vehicle. This would require a device to record the transmission then retransmit it in the event that the system doesn't anticipate it. To combat this issue, the majority of keyless entry systems use a method called rolling code that guarantees that each new transmitter signal received by the car has a different counter value than the previous one.
Batteries

If it doesn't work then you'll be required to determine if your fob is suffering from a more complex issue that requires a professional diagnosis.

Be sure to dry them completely before reinstalling batteries.

Another possibility is that the door sensor for your car's lock isn't working anymore.
