I have a 2014 Honda Civic LX. Bought from the dealership with two keys. I used one key for almost 60,000 miles. This is about when the batteries in our keys normally die. Key suddenly stopped locking the doors. Car would still register the fact that I pressed the button. Lights would flash. But wouldn't lock. It WOULD still unlock the door. The physical key itself still worked. Checked with the other key. Other key has no problems at all. Figured it was the battery. Replaced the battery. Still no go. I checked the new battery with a multimeter, and it's good. It's not like the car doesn't register the first key's being used at all. It just won't lock the vehicle. Any ideas?
