How to program immobilizer ECU KEYS after ECU swap Toyota LEXUS SCION no tools needed

– [Dan] Hi this is Dan from Today I’ll show you how to program a new, or used, hybrid ECU to a 2009 Toyota Camry. The ECU is located on the firewall here, we replaced it with a new one. Here’s an old one. And of course, once you (shuffling)
replace it, and wanna start the car, (car beeps)
I push on the brake pedal. The car does not start,
does not show ready on it. What you’ll do, it’s a simple procedure, but it will take 30 minutes. You leave the ignition on. You will leave the ignition on, go under (shuffling) the steering wheel, and what I have here, I’ll
show you, is a little jumper. I did mine with a fuse in case you connect
it in the wrong place and will short out, so
just burn this fuse. Otherwise, you’ll need a
jumper, you can use a paper clip if you don’t really care if
you burn something in the car, or a fuse in the car. More likely that’s gonna be the fuse. And here, I’ll show you the
instructions on how to do that. As you can see, this is the
the OBD data link connector. We’re gonna jump the 13 and five. So 13 and five is number four, from left to right, and same here. But your connector can be this way, or the other way around, so you always want to make
sure pyramid-type deal to the top and then count that way. So, I’ll show you on the car. So, as you can see, we
have ours right here, and ours is located same as
on the picture that we had, so what I’ll do with the ignition on, I’ll count one, two, three, four. (clicking) I’ll put it in there, make sure you’re not touching
any other connectors, or pins, and same with over here. (creaking) And now that we have a good connection, double check, make sure
we’re in the same page as noted in the picture. So one, two, three, four. One, two, three, four. Pyramid-type deal. Going up, so we will plug that in. And of course we’ll have to (phone clicks)
set it on a timer for about 30 minutes. I set mine on 29 because we
probably already had a minute since I was talking, so 30 minutes. After 30 minutes, I will
come back and show you that the car will start. So that’s how you program a mobilizer, to the new hybrid ECU. Back in a minute. Alright, I got 35 seconds. And I did forget to tell
you, when you do connect those pins together, all the
lights on the dash will be blinking, so make sure that’s
the way it’s supposed to be, and it will be blinking for 30 minutes. So, I got 15 seconds. And then in a couple
seconds I’ll just shut off the ignition, remove my
pin, and then start the car. (shuffling) (♫ Marimba alarm ringing) Alright, my timer’s done. I will shut off the ignition, remove my pin, and of course, (phone chimes) (car beeps)
As you can see, it’s ready. The car’s working, the RPMs,
and all the lights are off. So, that’s how you program the hybrid ECU.

  12. Hi thanks for your video! I just wondering if we can do the same process on toyota tundra 2007 v8 5.7, 4×4 any ideia plz ??? Thanks bruv

  13. Will this reprogram the existing computer? We've lost all three keys for the car and hope to program using new keys without paying a zillion dollars…

  14. It really is 4 and 13, not 5 and 13. It happens that 4 and 5 are linked together, tied to ground in most models, but if your car has not those two tied together, then 5 and 13 will not work. Anyway, the way you know it is working fine is if the lights in the dash start flashing randomly when you do this. And yes, this will work in most Toyota models from around 1999 to the present.
