Is it a different computer then waht came with the car? If so, it may have something to do with the computer not recognizing the key

If it is the stock ecu there should be no reason to reflash. It could be a bad ecu.

Disconnecting the battery on an OBD2 vehicle won't do anything to the computer no matter how long it's undone.

on some it will erase them. we have to go through certain procedures at work involving an obd 2 connector and a jumpbox becasue of rare cases when we change batteries

However, this is completely abnormal.

have never run into one that would erase the memory by leaving the battery disconnected. I sold parts for years to commercial customers and worked on them myself and haven't ran across this personally although anything is possible.
