2. Toyota Model: Avensis. Posted September 7, 2008. I have exactly the same problem as described by gwgraham. Even try removing the fuses under the steering wheel and removing the Battery but still cannot reset/disable the alarm. Found a few resetting and key programming sequences in this forum but none of them works. yes when you approach the car you can just open the door without getting key out and its a push button start. With the spare key i do have the option of just taking the Battery out, but with the key i use day to day i wanted to turn off the keyless. There is a way of doing it on some keys as there are loads of videos on youtube about it, but it If your fob doesn't open the door then it's either timed out or your battery's dead. If your alarm lights are flashing on your dash then your battery's likely not dead. You can check your battery by opening the engine lid and putting a voltmeter on the battery terminal in the engine compartment. This video will show you how to replace the battery in your Toyota Smart Key.Make sure to follow us-----Twitte 09 avensis, key will lock ok, but now the open button won’t work, key lights up and after a number of presses 20+ will open the car.
