LC 100 Locking problem resolved

A few weeks back, I posted about a problem my LC 100 had developed with the central locking system. Basically, it would unlock but would not lock (either from the remotes, the keys or the inside switch.
Toyota have had it for a full week and have fixed the problem. It was a burnt out relay, as many people had guessed.
Why did it take a week to repair? Because to access the relay involved, the dealer told me they had to remove the entire dash, the aircon and the heater box. Fortunately, it was all done under warranty.

(Just posting this in case anyone else has a similar problem.)
