Key Fob Not Working? Causes and Fixes

The key fob is designed to help drivers unlock and control their vehicles at the press of a button. However, in case it malfunctions, your daily routines could get disrupted because of the difficulty in accessing your car.

Many people have experienced faulty key fobs while believing they cannot be repaired; however, in most cases, the issue is caused by minor faults that can be easily resolved by a locksmith in Lithonia, GA. Read on to learn some of the reasons your key fob may stop working. We also shared some practical solutions.

Dead or Weak Batteries

With frequent use, the coin batteries that power these tiny remotes gradually run down. This means the signal sent to the car becomes too weak to be detected. Such defects may cause the locks to malfunction.

Signal Interference

Key fobs use radio waves to communicate with vehicles. This communication may be interfered with by specific surroundings. Other electronic devices, large metal objects, and parking structures can easily disrupt the signal and make the car unable to receive the command.

Internal Damage

Key fobs are small electrical tools that are prone to wear and tear, moisture, and drops. So, in case the buttons or the inner circuit board are damaged, it can completely cease to give out a signal. And the remotes often fail unexpectedly because of physical damage.

Lost or Corrupted Programming

The key fob may occasionally become disconnected from the car's system. This could happen after a system reset, electrical operation on the vehicle, or even after battery replacement. The car will stop recognizing the remote when the programming is out of sync.

Ways to Fix Key Fobs That Is Not Working
