Recently had to replace my 99 Passat battery. Suddenly quit. Would not start one Saturday morning after working fine the night before.

Interestingly, there may have been a warning. For a few weeks before this the remote key would sometimes not work – not at all. Open door manually, then the remote would work again. This happened 10 - 12 times. Has not happened in the 2 weeks since the battery was changed.

I have a 1998 Passat and a similar thing has occurred. Although not all my doors would lock once I engaged the alarm. Sometimes it was the passenger door, sometimes the rear driver's-side door. Just wouldn't lock. This morning, I have to huff it down to Kragen to grab a replacement Exide battery. Not bad for 6 years, I must say...
