The most common culprit behind a failing car key fob is a dying battery. As the key fob battery runs low, the device's transmitter loses its range resulting in weak signal strength, inconsistent results, and having to click repeatedly to unlock doors. However, your car key fob may not work even after a battery change and this happens due to a number of possibilities.
Let's look at the possible reasons your car key fob is not working after a battery change.
Step 1: Manually unlock your car door with your key and lock all car doors.
Step 2: Turn on the ignition and press the "Lock" button on the key fob.
Step 3: Turn the key back to the "Off" position and then turn the key to the "On" position after five seconds.
Step 4: Repeat step 2 and step 3 at least three times and end with the key in the "On" position at the end of the cycle.
Step 5: Listen for a lock sound that indicates that you've entered the programming mode. Lastly, press the lock button within five seconds of entering programming mode, and the process will succeed.
