Hello: My name is Stuart and I just purchased a 2004 Tundra Access Cab. Suddenly the automatic door locks are locking without the push button command to Lock. When I unlock the truck with the key fob and do not get into it, the cargo light goes out in the normal interval and about 30 to 45 seconds later the truck doors lock themselves while I am standing there next to it. Any ideas what the problem might be. Thanks in advance for any assistance you can provide me.
