Hi i've recently purchased a five year old LS430 and three times in the last week when i've returned to the car after it being used for a short journey (between 1 to 5 miles) i can gain entry into the vehicle but it does not seem to recognise the key to allow the ignition to be switched on. I retrieve the spare key from home (between 10 and 40 mins) and up to now doing that has got me going again. Of the three keys that came with the vehicle it doesn't matter which of the keys i use the problem has occured with all of them. Has anyone had this or a simular problem?
