Ls430 Key Problem?

[FoxPond]

Back on again guys , not sure what the problem is but someone out there hopefully does.

Key fobs both have new batteries from lexus.

Can enter car no probs , all Elecs windows etc fine

Red and green light shows next to the ignition , insert the key fob and both lights go out .

Will not allow the key to turn , wheels are in the straight position and steering not locked .

Wiggling the wheel or key does not help . It just fails to allow the ignition to turn.

Intermittent fault which has happened again today so can't use car .

Disconnected Battery and reconnected after 5 mins. Did not work

Any ideas please?
