Got my first car from my cousin a big standard 16v 1.2 just had it serviced and got cam accessory belts changed and water pump, once getting the car noticed central locking didn't work on the key fob. Took the fob apart and there's no battery at all, so not a clue to see if it's still coded with the car or not... Anyone know an easy way of coding them if it's decoded!? Cheers gents!
