Thanks for the advice, I emailed them about my 2021 model, they replied with a call next day and booked my vehicle in with the local dealer next week, all free of charge which is what you expect from Lexus
Hi
My keyless entry fob has stopped working on my 450h and I only have the one fob.
Unusually last night the alarm sounded for no reason and I went to the vehicle and unlocked/locked it stopping the alarm.
When I tried to use the car today, the keyless feature didn't work and when I press a button on the remote, the red light flashes but nothing happens on the vehicle.
I changed the battery to be on the safe side but still the same.
Many thanks
Gerry
