    lock the car manually, then try and unlock with the remote. if the car thinks there's a door open it won't lock with the remote, but it will unlock or attempt to unlock even if the car is already unlocked.

    tryed that if car is locked or unlocked key remote will do nothing apart from a flash from the light in the corner of the key.

    try recoding one of the keys:


    1 Drivers door open
    2 insert Key in to ignition -remove
    3 using the central locking switch on the drivers door LOCK to UNLOCK 5 times ie forward/back counts as one
    4 close/open door
    5 lock to unlock another 5 times
    6 insert key in to ignition
    7 off to on to off .. once to add a key .. twice to rewirte.. remove key
    8 after this the door locks will respond
    9 while this is happening hold down the lock button on the key and press the unlock button on the key 5 times .. release and press unlock once

    Hey, I know this has nothing got to do with this post, but a quick question, if I got a 2nd key with a chip (un-coded), and tried this, will it code the key to my car without having to go through the manufacture? Would save a nice few bob! I have a 01 Corolla by the by. Thanks. :D

    that will only code the central locking, the immobiliser is a seperate procedure, and AFAIK needs the Toyota diagnostics computer to code in the immobiliser chip to the car.
    Not 100% sure, check with dealer.

    also procedures aren't the same for all Toyota and Lexus models, so it's unlikely that the above would code your central locking.

    thanks for the help mate, tryed all above with both keys and still nothing. on one key there is also a button to pop the boot open it doesnt work ethier, i reckon i must be the device in the car that recives the signal frm the key as unlikely both keys go faulty at the same time any idea wat this is and where it is. maybe next option go to a toyota garage and see can they hook up to computer see does it see anyting wat do u think, thanks again for your help.
