Smart Key And Vehicle Won't Talk To Each Other.


Recommended Posts

My car is not recognising the smart key which had a new Battery a few weeks ago, it will not open the doors or turn in the ignition even though it did last week after being left for a month unused. I have tried resetting by pressing the door button at the same time as the key button but to no avail. Does anyone have any idea of how I may resolve this please? Cheers.

P.S., I'm not keen on Lexus' idea of the AA trailering there for a ride on their diagnostic machine @ £50 + VAT.

Do you have any working keys? If you do you can reprogramme a key that does not work - here is the thread where the answer is http://www.lexusownersclub.co.uk/forum/index.php?showtopic=45917

I saw this somewhere so it also may help. - I think it was ehow.


    • 1
      Close all of the doors and windows for your Lexus, then lock and unlock the driver's side door with your key.
    • 2
      Enter the car through the driver's door and close the door behind you.
    • 3
      Insert your key into the ignition and leave it there until the security light turns on.
    • 4
      Leave the key in the ignition for 15 seconds after the light turns on and press the brake pedal five times.
    • 5
      Remove the key from the ignition and insert it again to start the car with the smart key.

Good luck

Bren
