I just replaced all 5 door lock actuators on the '99RX (J-O-B). All the actuators are working by way of manual switch, but key fob doesn't do anything. Key starts the car normally. Battery was disconnected for about three weeks. Did the computer "unlearn" something? Any ideas about how to fix? Thanks.

Does the LED on the key light up when you press any button?

I wish I could say you have solved the problem or at minimum diagnosed the problem.
If every thing works with the other key fob then for sure the current key-fob transmitter is bad.
Other possibility is the receiver maybe bad [if the second key works then the receiver passes the test].
There can be a handshake issue too. I would suggest not to re-program unless the problem is verified. Please avoid the immobilizer reprogramming steps [I am assuming, you can still start the RX with the malfunctioning key-fob]
Dealer visit will be costly but convenient. There are reprogramming steps in the DIY link.

Please first make sure that you need to reprogram
