Common Causes & Solutions of Keyless Entry Remote Failure 

Dead Battery 

Dead battery is one of the common reasons behind keyless entry remote failure.  With time, the remote battery loses its charge, which affects its signal transmission. The time comes when the battery dies, and it completely stops transmitting signals. Secondly, extreme temperatures accelerate battery depletion. 


If your keyless entry remote suddenly stops working, replace its battery.  Most remotes use standard coin cell batteries, which are available online or at local hardware shops. You can see the battery replacement instructions in the vehicle’s manual to avoid any errors. 

Signal Interference 

Nearby electronic devices, powerlines, and radio signals interfere with the remote’s signal frequency.  Sometimes, it completely disrupts the communication signals between the car and the remote, causing remote failure. 


Try using a remote from another location to see whether the key fob remote failure is due to signal interference or any other issue. Move away from power lines and electronic devices and check if the remote starts working. If the issue persists, then there might be some other problem. You must seek help from a trusted auto locksmith. 

Faulty Remote or Receiver 

If neither the remote battery nor the signal interference is the culprit, then the problem might be in the vehicle receiver or the remote. Sometimes, the device’s components wear out and cause remote malfunction. 


If none of the above solutions were helpful, inspect the remote and receiver for visible damage or corrosion. Clean the contacts on the remote and receiver with a soft cloth and alcohol to ensure proper connection.
