I had to replace the battery in my key ('97 - old style with batteries) and tried to initialize it. I followed the steps in the user manual to the letter:
1. get in car and close driver door (all doors were closed)
2. put key in ignition and turn to position 1 briefly (less than 5 sec.) then back to position 0 and remove.
3. hold down unlock button and quickly press lock button 3 times (within 10 seconds)
4. key LED will flash slowly for 10 seconds (it did)
5. central locking will automatically lock and unlock car to confirm process worked (it did)
I only have the one key (other was destroyed in a swimming accident

and haven't had it replaced yet).
So when I put the key back in to try and start the car, the engine just clicks and all the lights on the dash flash, as though the initialization process did not work.
As far as the doors go, the key works fine. Remote lock, unlock and trunk all work. Just can't get the car started.
Since it appears from steps 4 and 5 that the process worked, I'm wondering could it be anything else? Like a blown fuse? Or too many unsuccessful attempts? Is there anything else that I could try to reset?
Thank you for your help.
