How do I bypass the immobilizer on Toyota Tazz 1.3 2004 model

SOURCE: 2000 Model toyota camry lost all keys

If you have lost all keys, you must see a Toyota dealership to have them reseed the immobilizer and cut a new key or keys. They shouldnt charge you more than 2-2.5 hours labor plus the cost of keys. I do these all the time

It is stamped on the inside of the disc. You have to remove the disc.

SOURCE: Toyota Tazz window winder

Toyota Tazz driver side window refused to wind properly. Problem was that winder mechanism and window separated - old glue. Found some input from Ben on this forum. Some pointers after doing the job today.
Step 1 - remove the arm rest - two screws
Step 2 - remove the screw holding the door opener handle.
Step 3 - remove the C-clip holding the winder handle. The clip is round but the ends are slightly bent outward - to fit back easily. Use a large screwdriver to force a small opening (thus moving the panel slightly inward). I took a piece of thin solid wire and bent it into a loop. This looped wire I hooked around the one end of the clip and pulled in the opposite direction towards the inside of the car. The open end is towards the part of the handle you wind. Make sure the top of the handle faces towards the interior of the car (door is open wide). The clip shot off (as Ben warned) but landed in the car.
Step 4 - the door handle (square) must be slid forward and outward towards you. Will now be loose but is held by the rod going to the lock.
Step 5 - loosen all clips carefully by pulling the panel forward - large screwdriver works.
Step 6 - lift up the panel - and push the door handle holder through the hole in the panel. The panel will now be free.
Step 7 - the window can be removed in this case where window and mechanism seperated by simply pulling the window upwards and outwards.
Step 8 - I used a small grinder and removed most of the glue - but not all.
Step 9 - put the window back into the door making sure it is correctly aligned in the side-sliders.
Step 10 - I used an epoxy 2-part glue (Pratley) and placed some glue in the holders. Position the window and mechanism correctly (using glue I left as marker). Note that only 2 holes in door panel can be used to see or fit glue.
Step 11 - Mix more glue and apply front and back. Now place some grease in the mechanism rail (horizontal) and wind window to the top. Leave to dry.
Step 12 - replace all in reverse. Clip pushes on easily - I used a small long-nose pliers.

Cheers,

You can't. And it never has happened. Even the old systems had to have that signal. They just bypassed the key. It can't be done now days. Have the codes read and go from there.
