I was going out to eat tonight, and when I left my house, I hit the unlock button on the key; doors opened like usual. Then I get to the restaurant, and get out. I hit the lock button; nothing. The unlock button...nothing, trunk, nothing...panic button, and still nothing. Well I just lock the doors manually and go eat. When I come back out, I try to use the remote to open the doors, and nothing happens. I drive straight home, and when I get to my house, I try again, and the lock button works. I tried all the buttons, they all worked. Has this happened to anyone else? Why would the inkey remote just suddenly not work and then start working again?
