  • Master key reprograming - remote not working

    I recently purchased a 2003 GXL prado.
    I soon discovered that the only key supplied was the (grey) sub key.

    When I called toyota they said I need to change a whole heap of computers to reprogram a master key which would cost around $2000!!

    Anyway, after a lot of googling and calls I came across a shady locksmith who said he could reset the computer to create another master key.

    As it turns out my mate used to own a prado and still had a key with the remote which he did not need.

    So I did the following.

    I ordered a empty shell from ebay for $10.

    I got the key of my mate and unscrewed the remote "guts" and put it in the new shell.

    I called the locksmith guy and he came around.

    He was able to create the master key using some kind of dongle which he plugged into the vehicle.

    He then sat for another hour after which he gave up trying to program the remote to work.

    He says that the master key is now working but since the remote is a different frequency, he can not get the remote to pair up.

    I am able to get the vehicle into registration mode, but when Pressing the keys on the remote, nothing happens.

    Now I am trying to find out what the story is with frequencies?

    I don't really want to fork out $400 for a remote from toyota.

    I found remotes on ebay in the US for the GX470 which is sort of the same car.

    Does anyone know if they will work as a remote?

    or can anyone suggest where I can get a cheap remote from?

    Hi rosshire
    There are 2 proceedures when programming a new key, 1 is adding the key transponder to the immobiliser ECU (this allows the key to start the car), 2 adds remote to central locking.

    I have sent you a PM if you reply with your email I will forward you these proceedures.

          Hi matt! Is the instruction includes on how to program the immobilser as well? Will it work with a new set of key?
          Thanks.

            The instructions do both the immobiliser and the central locking (seperate procedures), but you need 1 working master (black) key, will make more sense when you see the instructions.

              Just had a go at the procedure..
              This is the same thing I was doing..
              Only problem is that once the vehicle goes to registration mode and I need to hit the buttons on the remote to register it to the computer, there is no response.
              I have been told that the remote is on a different frequency and that’s why the vehicle cannot see it when I press the lock/unlock buttons

                  Hi rosshire,
                  I had the same issue when I was trying to program the key for my wife's Echo and couldn't do it.
                  Took that to Chadston Toyota Dealer and they quoted me $60 to program it. But they couldn't do it either and said that they
                  can trick the computer for the immobiliser but wont work for the door because of different frequencies.
                  Ended up paying $375 for the key from Toyota.

                  That was year ago and I did try the same key for my Prado 3 Weeks back and it worked !!
                  Looks like even they looked the same you need different ones for each model.. (pre-setted frequencies may be ) : (

                    You're the Man Matt!!

                    I have been trying to get my spare key working for about a year. I had already programmed the remote, and the instructions for that part of the proceedure are readily available on the net, but getting the key to register with the
                    special box imobiliser thing was proving impossible.

                    You instructions worked!!!

                    Thanks very much. :-)

                              Hi Waltec
                              I bought the car with only one but thankfully master key.
                              I ended up buying a new key and transmitter off ebay which I was assured would work fine, just take it to Toyota to program.
                              Took it to Toyota and they managed to program it for starting the car but the remote locking and unlock was not so successful.
                              They said it was the wrong frequency.
                              Would your instructions get this to work?
                              Could you send them to me?
                              Cheer
