If the keyless entry doesn't work after putting in a new battery try reprogramming it as if it was a new key as follows:
Open driver door, keep it open and in the unlocked position
Put original key in ignition and pull out
Lock and Unlock the doors 5 times
Close the door and open the door
Lock and Unlock the doors another 5 times
Put the Master Key in the ignition, turn it on and then off and remove from the ignition
You should hear a confirmation beep within 10 seconds and the door locks should actuate
Push the button on the new key
Close the door and open the door
Push the button again on the new key
That should do it!!!
good luck
