It's an easy feature that makes driving a car more comfortable and safe. The keyless entry system, as any other device, can be damaged by repeated use or other elements. If you are having issues with yours, you can either visit the dealer or call a locksmith.
The way a keyless entry system operates is by sending out radio signals, and then searching for a response signal from the key fob. If the system recognizes the signal, the vehicle's doors are unlocked and the onboard computer is activated. Certain systems have another receiver mounted on the car's trunk that will open automatically when you put your foot underneath it.
Each key fob comes with a unique digital identification code that is assigned by the manufacturer. The fob is programmed with an exclusive process known as "programming". This usually involves turning on the car's ignition multiple times in a particular sequence, and could also involve pushing or pulling different buttons and levers, or removing fuses.
Once a key fob is programmed to your specific car's keyless entry system it transmits its digital identity code as well as a function code that tells the car what to do (lock, unlock or open the trunk). The receiver on the car verifies the transmitter's identity through an authentication and encryption process. If it's authorized the onboard computer unlocks the vehicle and begins the engine.
There are concerns that a skilled criminal could intercept the code that's transmitted between the key fob and the car. This would require a special device to record the transmission and then transmit it again when the system isn't expecting it. To prevent this from happening issue, the majority of keyless entry systems rely on the rolling code method that guarantees that each new transmitter signal received by the vehicle has a different counter value than the previous one.
Batteries
A dead battery is the main reason for the car remote to not work. If you have an extra key fob, it's a simple and inexpensive fix.

Certain key fobs might come with fasteners that are able to pop out and scatter key fob pieces all over your living space.
The case of a majority of key fobs has a single screwdriver hole. To open it, you can make use of a pry tool. However, before you begin by putting the tool around the outer edge of the case like you would peel an orange or apple.

After the new battery has been put in place, test your key fob again to see if it fixes your problem. If not it, you'll have to determine if your fob has an issue that's more complex that requires professional diagnosis and repair.

Another possibility is that the door lock sensor in your vehicle isn't working anymore. It's a tiny metal component that's attached to the door lock button on your key fob, and it's not unusual for the sensor to break after long-term use or exposure to extreme weather conditions. Press your key button several times without locking or unlocking your doors. This resets the sensor.
