I recently purchased a 2006 BMW 325i... never wrecked 18k miles. But a few days ago the keyless entry stoped working so i figured it was the battery in that. But also the the lock/unlock button on the dash does not do anything except when i unlock the drivers door it will lock it. An electrical problem? A fuse? And then yesterday my driverside head light went out. Just a coincidence? Any help would be appriciated. Thanks.
