When I bought my 300 the seller had only one key, a factory non-remote Lexus key that seems to work correctly. The key will lock and unlock the drivers door and trunk. When I try to lock or unlock the doors either by key or by button I hear the motors work but the locks do not move into the lock or unlock position. I was lucky enough to get the original window sticker with the car, it originally came with the remote key. I need some advice on where to start restoring the central lock system to working condition and then re-integrating a remote key. Any input will be appreciated. Thanks!
