How to change the car key battery
A car key fob battery can also die, just as any other device that uses a battery. They often fail at the worst times, which can lead to frustration. The batteries can be easily replaced.
Modern cars have some kind of key fob. These key fobs can be attached to the keyring or used to communicate with the locking/unlocking mechanisms. The key fobs transmit an RFID signal wirelessly and operate on the power of a lithium battery. The key fob's batteries last between 2 and 5 year.
The car fob's battery may become weaker during this time and the remote device will not work. You may be unable to enter the car or use keyless functions. It is easy to replace the car key fob battery. Here's a guide to changing the car key fob battery.
What happens if your keyless remote batteries dies?
If your keyless entry has a START button but no mechanical key slot, you can still start the car. Push the START button using the key fob. Some manufacturers offer a backup system that will allow this method to work even if the battery in your key fob is dead.

Use key fobs
The popularity of key fobs grew in the late 80's/early 90's, when they were widely available in cars. Infrared waves were used in the early days of keyless entry systems. However, these required a line-of-sight to work. Because of their security and reliability, RFID key fobs quickly became the preferred technology.
Many advanced functions and features are now available in keyless entry systems. A few key fobs can open the rear hatch, which is great for those who have heavy shopping. Other RFID key fobs are capable of starting a car's engine. This is useful for warming up the engine before going on a short ride.
Lock your key fobs
Wireless remote keyless systems manufacturers must ensure that the device is secure. Although wireless key fobs offer greater security than physical keys, thieves can still exploit them if the system is not properly secured. These vulnerabilities must be addressed by RFID keyless entry systems.
Modern keyless entry systems prevent other devices from intercepting their signals. Many key fob transmitters use an encrypted signal that changes each time it's used. However, the receiver can still use that signal to unlock/unlock the vehicle doors.
