Had a problem with the Remote Control (two of them) not locking and unlocking the Holden Astra 2000 model. I thought it was the battery as the red led light didn’t go on both the remotes so decided to change them. After changing them, the red led lights did go on but the car still didn’t lock and unlock. After some research I had to re-sync the remote controls with the car. The video shows you how to do it. Here’s the steps:<\/p>\n

1. Insert the keys in the ignition and twist the keys so that it’s in position II (2) the lights on the dashboards should go on
\n2. Press the lock button and you will notice the car will lock and unlock
\n3. Take the key out and test. It should now work. Done it to both keys and worked like a charm.<\/p>\n
