Car remotes are a excellent convenience for drivers. They can unlock doors, access trunks, and even start the engine. However, they can stop working at inconvenient times.
Before you head to the dealer, consider some quick solutions in case your key fob isn't working. These steps may save you money.

The keyless entry system, just like any other device, may be damaged by repeated use or by other factors. If you've had issues with yours, you have two options: Go to the dealership or call the local locksmith.
A keyless entry system operates by sending radio signals and then searching for the response signal from a key fob. If the system recognizes the signal, the car's doors are unlocked and the onboard computer is activated. Certain systems have a second receiver on the trunk of the car that opens automatically when you put your foot on it.
Each key fob is assigned an individual digital identification number by the manufacturer. A specific process of technology called "programming" is used to make sure that the fob is set up with a specific car's system. This usually involves turning on the ignition of the vehicle several times in a certain sequence and may include pulling or pushing different buttons and levers, or the removal of fuse.
When a key fob is programmed to your car's keyless entry system it transmits the digital identity code along with a function code that instructs the car what to do (lock or unlock the trunk or open the trunk). The receiver in the car verifies that the transmitter is who it claims to be using an authentication and encryption process. The computer on board will allow the vehicle to be opened and start the engine when it is authenticated.

This would require a specific device to record the transmission and then transmit it again in the event that the system doesn't anticipate it. Most keyless entry systems utilize rolling codes to prevent this. This ensures that every new transmitter signal received by a vehicle has a counter value that differs from the previous one.
