Keyless Entry System
There's no need to search for keys in your pockets or purse. Just walk to your vehicle, press the button on the keyfob, and the doors will unlock and the engine will start. It's a convenient feature that has made the world of car driving more enjoyable and more secure. However, just like any other device, the keyless entry system can be damaged by frequent use or due to other reasons. If you are having issues with your system, you can either visit the dealer or call a locksmith.
The way that a keyless entry system operates is by sending out radio signals and then searching for a corresponding response from the key fob. If the system detects the signal, the car's doors are not locked and the onboard computer activated. Certain systems have another receiver mounted on the trunk of the car that will open automatically when you put your foot underneath it.
Each key fob is given a unique digital identification code by the manufacturer. A specific process of technology called "programming" is used to set the fob up with the car's specific system. This usually involves turning the car's ignition several times in a certain sequence. It could include pulling or pushing various buttons and levers or removing fuse.
Once the key fob is programmed into your car's keyless system, it transmits a digital identity code as well as a function-code to instruct the car to (lock, unlock or open the trunk). The receiver in the car confirms that the transmitter is the person it claims to be by using an authentication and encryption procedure. The computer on board will allow the vehicle to be opened and start the engine if it is authenticated.
There are concerns that a clever criminal could intercept the code that's transmitted between the key fob and the car. This would require the use of a device that records the transmission, and then retransmits it in the event that the system doesn't want it. To help combat this, most keyless entry systems rely on a method called rolling code, which ensures that each new transmitter signal received by the vehicle has a different counter value than the previous one.
Batteries
A dead battery is the most frequent reason for car remotes not to work. It's a cheap and easy fix if you have another key fob at your desk to replace the old one with.

The case of a majority of key fobs has a single screwdriver hole. To open it, you'll need to make use of a pry tool. However, before you begin, wedge the pry tool along the outside edge of the case like you would do when peeling an orange or apple. Do not apply too much pressure, since the case of the fob is usually made of plastic and can break or crack if apply too excessive pressure to it.
If you're ready to replace the battery, be sure to match its size and style to your key fob. Certain fobs require two batteries, whereas others have just one. The wrong battery can render your key fob remote useless.
After the new battery is in place, try using your key fob again to see if it fixes your problem. If it doesn't work you'll need to determine whether your fob is suffering from something more complicated that requires professional diagnosis.
