Well that question is too general. What year and what make is the vehicle? Is it a brand new key fob? If it is brand new it may need to be programed to the vehicle. The battery may be dead in the fob. The fob may also have a broken contact inside of it. I recommend taking your key fob and vehicle to the dealer for diagnosis.

If your Ford Freestyle is showing a flashing red light with a car and lock symbol, it typically indicates an issue with the vehicle's keyless entry or anti-theft system.

Try replacing the key fob battery, or if that doesn't work, you may need to reprogram the key fob or consult a professional for further diagnostics.

To reset a 2006 Mercedes C-Class key fob, first, insert the key into the ignition and turn it to the “On” position without starting the engine. Press the “Unlock” button on the key fob for about 5 seconds, then release it. Turn the key back to the “Off” position, remove it, and then test the key fob to see if it functions properly. If it still doesn't work, you may need to replace the battery or reprogram the fob.
