What to Do If Your House Key Won’t Turn in the Lock After a long day at work, the last thing you want is to come home, put your key in the lock, and find that it won’t turn. The smart lock does a long 5 second beep and doesn't work when I put my hand over the door handle, but the car WILL lock when I press the "lock" button on the key fob. And if you're leaving pets or anything that is going to move inside the carthen press the remote lock button twice (or turn the key in the lock cylinder twice) to disable the interior motion sensor. I wanted to post on here before I did something potentially dumb (like blasting wd40 into the keyhole). This needs to be done in a good pace, but not too fast. With this, it is a very important security component that keeps the interior of your car from easy access.
