Not got any new tricks to try, but just wanted to say that I suffered same problem this morning, first time ever in almost 3 years. Parked on hardstanding at home, all 3 remotes failed to unlock car, although managed to open boot once. Lexus Croydon suggested wireless interference the problem, and suggested RAC be called, as they carry device to monitor such interference. RAC brilliant - here within 15 minutes and confirmed suspected cause and direction it probably coming from (dishes/aerials on roof of tower block a few hundred yard down the road). Opened car manually with key (alarm screaming, much to disgust of neighbours!), drove 20 yards, stopped beside RAC van, blocking line of sight of suspect devices, and all OK. Got back home tonight after driving to work, and it is still OK, both locking and unlocking. RAC man told me this not an uncommon problem in London area, not particularly confined to Lexus vehicles.
Hi,
Interesting reading- I have an IS300 Sportcross and always find that it wont lock when I park outside my Mum's house, or it struggles and then does it eventually. Once found that it wouldnt unlock- nearly had a panic attack thinking of the chas that would cause but eventually it unlocked. I blame it on interference too!
