Purchased replacement key from Ace a few months ago. This weekend, I disconnected the car battery for about half an hour. After reconnecting the car battery, the car would not start with the duplicate key. It did start with the original master key. Ace reprogrammed the duplicate key again and it appears to be working fine. The duplicate did lock /unlock doors as well as open the trunk even though it would not start the vehicle. Is there something special that I should be done when disconnecting the battery, or is this likely a key programming likely issue. Thank you for your opinions!
