Keyless Entry System

It's a simple function that makes driving a car more comfortable and safe. However, just like any other device, the keyless entry system could fail due to repeated use or because of other factors. If you've had issues with your keyless entry system, there are two options: Go to the dealership or call a local locksmith.
The way that a keyless entry system operates is by releasing radio signals, and then searching for a corresponding response from the key fob. If the system is able to recognize the signal, the vehicle's doors are unlocked and the computer on board is activated. Certain systems include an additional transmitter in the trunk of the car which can be opened when you put a foot under it.
try what she says is given a unique digital identification code by the manufacturer. The fob is programmed with a proprietary process called "programming". This usually involves turning on the ignition of the vehicle multiple times in a particular sequence and may also require pulling or pushing various buttons and levers or removing fuse.
Once a key fob has been programmed into your car's keyless system, it transmits a digital identification code and a function code that instruct the car on what to do (lock the trunk, unlock it or open the trunk). The receiver on the car checks the authenticity of the transmitter by an authentication and encryption process. If it's authorized the computer on board unlocks the vehicle and then starts the engine.
A savvy criminal could steal and use the code sent between the keyfob's and the vehicle. This will require a device that records the transmission, and then retransmits it later when the system doesn't expect it to. To help combat this, most keyless entry systems use the rolling code method, which ensures that each new transmitter signal received by the vehicle has a different counter than the previous one.
Batteries

Make sure you match the size and type of battery to your key fob when replacing it. Some fobs require two batteries, while others only have one. Using the incorrect battery could make your key fob remote useless.
After the new battery is in place, test your key fob for the second time to see if the battery has fixed your problem. If it doesn't then you'll need to figure out whether your key fob is suffering from an issue that is more complex and requires professional diagnosis and repair. It could be necessary to have the fob reprogrammed at the dealer or purchase a new one.
Buttons

To get rid of this issue, take off the batteries in a careful manner and scrub each button with the help of a cotton swab which is dipped in rubbing alcohol. Be sure to dry them thoroughly before installing the batteries.
It's possible that your key fob has been damaged in any way, for example, being dropped on concrete or accidentally scratched. If this is the case, you can test your key fob's functionality by using another one.

Press your key button several times without locking or unlocking your doors. This resets the sensor.
