Rep Power: 0

Hi guys, sorry to bother everyone. I've been searching this problem for a couple of days and now it's just itching away at my brain. My key fob central locking has stopped working and won't open the car on both keys. Now when I use them manually to get into the car the alarm goes off and will not stop until I lock the car from the outside manually again. I went to have the car key batteries replaced and they were the same. I'm not getting the little red flash on my key either when I click the buttons. Am I right in thinking that it's the actual car battery or do the keys need reprogramming? I have a 56 plate Honda Civic. Just wondering if anyone knows. Thanks.
