Your card doesn't expire but your skills do. Prepare yourself for a decent refresher course meaning get in the water as much as possible with a snorkel and fins. If you have a local diving operator, you may be able to negotiate to sit in on some classroom sessions/confined water sessions.
Consider yourself as an inexperienced diver again- even though your logged dives may be quite high. Consider keeping your depths conservative and therefore giving yourself the maximum dive-time as opposed to joining the 'advanced' group for deep dives.
I mention this because I see a lot of problems with people slapping an AOW card on the table without having recent experience in the water and expecting to be able to be as comfortable/efficient as they were last year, or in years past.
