right the problem is folks as follows. my central locking from the remote key got weaker and weaker a few months back then died. finally got round to replacing the battery and still no joy. checked the battery and it was a dud. replaced again and the battery is now good but wont code in. tested fob on a fob tester and appears that the fob is dead. got a fob online put a good battery in it but yet again wont code in. followed the guides on here and nothing no hazard flas nothing. tried one that come with the fob which was lock the door key in and out 6 times should flash then turn it to position 2 and press fob. this doesnt work either. and once again no hazard flash but this time the locks unlock after the 6th insert. HELP!!!!!!!!!
