Hi There, I have a 1993 LS 400 and the central lcocking has stopped working when I use the key in the drivers door. It works from the button and from the passenger door. Anyone help? Thanks.

sounds like the switch is gone in the lock

perhaps needs cleaning

Thanks, I'll check that. It may be coincidence but the battery has just died a death as well. The problem with the lock has been happening for the last couple of months though.
Thanks for the advice.
Ian
