A keyless entry system operates by sending radio signals, and then scouring for the response signal on a key fob. If the system detects the signal, the car's doors are opened and the onboard computer is activated. Some systems have another receiver mounted on the car's trunk that will open automatically when you waggle your foot underneath it.

This involves turning on the ignition of the vehicle several times in a specific sequence, and may also require pulling buttons or levers, or removing fuse.
Once the key fob is programmed into your car's keyless system, it transmits a digital identification code and a function code to tell the car what to (lock the trunk, unlock it or open the trunk). The car's receiver verifies the transmitter's identity through an authentication and encryption process. The onboard computer will unlock the vehicle and start the engine if it's authorized.
There are concerns that a criminal with a sly approach could intercept the code transmitted between the key fob and the car. This will require an instrument that records the transmission and then transmits it again in the event that the system doesn't want it to. Most keyless entry systems utilize a rolling code method to prevent this. This ensures that each new signal from a transmitter received by a car has a counter that differs from 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 cheap and easy fix. Fortunately, most fobs utilize regular watch-style batteries that can be purchased in hardware stores or big-box retailers for less than $10.

Be cautious not to damage any of the circuits or antennas within the case once you've removed your battery. They're likely to hold the key fob's program to your specific car and tampering with them will make it impossible to program (and most likely not work). If you must move them, do so slowly, as certain key fobs have fasteners that are able to open and scatter key fob pieces all over your living room.
The majority of key fobs have a single hole for an screwdriver or similar tool to open the case, however it's a good idea to put your tool on the outside of the case first, like you would peeling an apple or orange. Don't apply too much pressure since the case of the key fob is typically constructed of plastic and is susceptible to breaking or cracking when you apply too excessive force.
Make sure you match the size and style of the battery to the key fob when replacing it. Some key fobs come with two batteries while others need one. The wrong battery could cause your remote to become useless.
If the issue persists, you can try again with your key fob after installing the new battery. If it doesn't it, you'll have to determine whether your device has an issue that's more complex that requires professional diagnosis and repair. It could be necessary to have your key fob reprogrammed at the dealer or purchase a new one.
Buttons
The buttons on your key fob are pretty small, and are packed with delicate electronic components. Therefore, it's not surprising that they're destined to fail from time time. The good thing is, when your car's key button isn't working, there's usually something you can do to fix it yourself.
One of the main reasons a car key remote fails to function is that dirt or crud has lodged between the buttons. To fix this, remove the batteries carefully and clean each button using a cotton swab that is dipped in rubbing alcohol. Make sure to dry them completely before reinstalling batteries.
It's possible that the key fob was harmed in some way, possibly dropped on concrete or accidentally damaged by something sharp. If this is the case, you can test the function of your key fob using a different one.
Another possibility is that the door sensor for your car's lock has stopped working. It's a tiny, metal part that's connected to the door lock button on your key fob, and it's not uncommon for this sensor to break during prolonged usage or exposure to harsh weather conditions. To reactivate the sensor just press your key fob a few times without locking or unlocking your doors to reset it.
If nothing else works, you can always test the function of a spare key by opening and locking your doors using it. If the spare key doesn't work, it could be necessary to locate an 24 hour locksmith that can offer auto key repair to make your remote work again.
If your car's key fob is working, but it's still not locking or unlocking the vehicle, you may try to reprogram your computer system. If you've had the same key fob a time, it may need to be reprogrammed every few months in order to continue working with your vehicle. It's not the most ideal solution, but it's better than having to buy an entirely new remote.
