Immobilizer location? Problems?

I posted a question about this vehicle reguarding its a push button star an when I push to start nothing happens the dash lights go out an back on like a power ssupply problem but car trouble code b2799 came up so any way to solve this problem by just key the responds I got from this question was are u sufe immobilizer is the problem what else could it b need help prompto thanks

Just brought this vehicle runs great, but just today went to start, by the way its a push button start, push button to start the car does nothing no sound or nothing how do I reprogram the immobilizer to make start again

My car has an alarm system. I've been having problems with it. Can it be disconnected. If so can I do it or do I have to take it in to the dealership.

So here we go. I hope someone can help me with this I have spent hours out the back checking things. So I have two of the same vehicle listed above d4d 2l diesels they were both running fine. I then stored them out the back yard for a few years I have come to start them after swapping the batteries and they both wont fire up. They have fuel but don't seem to have ignition they crank over but wont fire up. The key will unlock the car but when I try to lock it the immobilizer just beeps and doors don't lock. So I can only assume I have an immobilizer problem its as if because the car batteries died the car has forgotten the key code. The car keys were fine I didn't have to change the battery in them. It is very odd as the two cars have the same problem. I only want to get them back up to scratch so I can make a few quid rather than them just sit in a scrap yard there to good for that? Please help

When leaving the car and arming the alarm system, after about two minutes the alarm will start going off. Even if I lock the car manually, after about two minutes the alarm will go off. Please advise.

Factory alarm. Nothing on dash to indicate anything out of order. If it is the battery on my key fob can I go to an auto parts store to get them?

My alarm keeps going off. I have to tighten the positive battery terminal but when I do the alarm goes off so I have to get in the car push the valet switch. When it is off then push when I have the key turned now the valet switch broke from pushing it so much. How can I just disable my alarm?

It sounds like you have a micro switch in the drivers door lock that has gone bad, because that is what happened to my car. I got a new latch and installed it the problem went away. Cost me $67.00 for the part. FYI
Here are wiring diagrams so you can see how the system works. (Below)

I look up a couple of sites on how to bypass a 1997 Toyota rave 4 immobilizer an I followed the one where it said to cut the two wires coming from key cylinder join them cut power to immobilizer box an it should work but all am getting is spark for about 4 seconds car starts and cut right off so my guess is immobilizer is still cutting in, I need help on which wires to attend to in order to fully bypass this immobilizer, which wires are the ones that shut immobilizer completely off, it has a Toyota vvs immobilizer system with 3 separate immobilizer boxes, I eliminate power to all the boxes but immobilizer still kickin in I think, I need your help had car for a while an it runs great besides that
