Q: Car won't unlock electronically, nor mechanically.

asked by on

The car had a actuator issue which got fixed and a new battery right before the actuator was fixed. None of the lights were on and it worked perfectly the day before. The car sat overnight outside, which it normally does, when i went to unlock it this morning, it would not open with the key fob, which had a full battery, nor the key. The car would not even beep as it normally does when you try to unlock it, nor was the security light blinking. When the key was in the door, there was no unlocking the doors, nor was there beeping either. you could still feel where the contact/point of where the door would lock and unlock though. It did rain pretty hard the night before so I'm wondering, could water of gotten into the ECU or fuses and wiped the electronics or something? Wiring in the door was fine and done while battery was unplugged, and car worked less than 6 hours before I tried this. Thanks for the help.
