Key fob was working fine one day, i went out and opened the doors with it. When i went to lock the doors next time it didnt work, the battery is fine just wanted to know if anyone had any ideas on how to reset? My key was not dropped just suddenly stopped???

They have a rolling code and may need resetting. Put the key in the ignition turn it on full ignition and press the lock button for 10 secs. Try it a few times if it doesnt work first time. You might need to have it recoded to the car or the plip may have just died and needs replacing.
