Keyless Entry System
Instead of having to fiddle around with keys in your pocket or purse instead, stroll up to your car, hit a button on the key fob and then unlock the doors and start the engine. It's a simple feature that makes driving a car more comfortable and secure. But just like any device it's possible that the keyless entry system can fail due to repeated use or due to other reasons.

The way a keyless entry system operates is by releasing radio signals, and then searching for a response signal from the key fob. If the system is able to recognize the signal, it's triggered to unlock the vehicle doors and also activate the onboard computer. Some systems have another receiver mounted on the trunk of the car that opens automatically when you put your foot on it.
Each key fob is assigned a unique digital identification code by the manufacturer. The fob is programmed using a proprietary process called "programming". This involves turning the ignition of the vehicle repeatedly in a predetermined sequence, and may also require pulling buttons or levers or levers or removing the fuse.
Once a key fob has been programmed into your car's keyless system, it transmits a digital identification code as well as a function-code to instruct the car to (lock the trunk, unlock it or open the trunk). The car's receiver checks the authenticity of the transmitter by an authentication and encryption process. If it's authorized the computer on board unlocks the vehicle and begins the engine.
There are concerns that a criminal with a sly approach could intercept the code that's transmitted between the key fob and the car. This will require an instrument that records the transmission, and then retransmits it when the system doesn't expect it to. To prevent this from happening issue, the majority of keyless entry systems use the rolling code method, 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 the car remote to not function. If you have an extra key fob, it's a simple and inexpensive fix. Most fobs are powered with watch-style batteries that are available at hardware stores or big-box stores for less than $10.

Most key fobs have one hole that allows the screwdriver or another pry tool to pop open the case, however it's a good idea use your tool to wedge it around the outside of the case first, like you would peeling an apple or orange. Don't apply too much pressure, as the case of the key fob is usually made of plastic, and is susceptible to breaking or cracking with too much force.
Make sure you match the size and style of battery to the key fob when you replace it. Some key fobs have two batteries, while others only need one. The wrong battery can cause your remote to become useless.
If the issue persists then you can try it again using your fob's key after installing the new battery. If it doesn't then you'll need to figure out if your fob has an issue that's more complex that requires professional diagnosis and repair. You may have to have the fob reprogrammed by an authorized dealer or purchase another one.
Buttons
The buttons on your key fob might appear small, but they are packed with electronic components. It's not surprising that they occasionally fail. The good news is, when your car's key button fails to function, there's typically something you can do to fix it yourself.

To remedy this, take out the batteries with care and scrub each button with an abrasive that has been submerged in ruby alcohol. Be sure to dry them thoroughly before installing the batteries.
It's possible that your key fob is damaged in some way, like being dropped on concrete or accidentally scratched. If this is the case, using another key fob to check its functionality may reveal that yours has been damaged and has to be replaced.
The door lock sensor could have stopped working in your vehicle. It's a tiny metal component attached to the key fob's door lock button. It is not common for it to fail due to weather conditions or prolonged usage. To reactivate the sensor simply press your key button several times without locking or unlocking your doors to reset it.
If all other options fail, you can always check the functioning of a spare key by trying to lock and unlock your doors with it. If the spare key doesn't work, it may be necessary to locate a 24-hour locksmith that offers automobile key repair in order to get your remote operating again.
