I have to replace all three computers because the car won't pair to a new key. Toyota informed me the
Anti-theft Alarm Control unit, Lock Actuator and EXU Aggregate had to be replaced. I found everything but the Anti-theft Alarm Control Unit.
 
I see but this does not make any sense why the dealer is telling you this. If all you are doing is making 1 extra key then you are doing something wrong. I suggest you read the sticky on making an extra key.
You need to make sure you have the correct key fob. The ones for push button ignition the procedures are different than the key ignition system. If you find it too complicated and don't understand something you should explain your problem what you are experiencing on this forum so someone can help.
 
Ok now we are getting some where. The dealer should know what they are doing but maybe this one is clueless or want to rip you off to the hilt.
When all the keys are lost you can't program a new key. The ECU needs to be reset. To do this this requires a reseed code. The reseed code allows you to create a new master key and then make more other keys. I would either go to another Toyota dealer or to a locksmith that specialize in making new fob keys.

They tried to reseed the computer, it didn't work. Told me all three computers had to be replaced as they weren't communicating with each other.
 
Rfspyder98, if your computers are all working normally then I would think it is not the culprit. If the reseed code part did not work then there is a problem with the reseed code generated. Some of the locksmith are very good at fixing this problem. You have to find one that has the expertise.
 
Assuming this not a push button start (i.e. key only), the components are: Transponder key amplifier on your ignition switch, Transponder key ECU (in dash behind security light), and the Engine ECU (under hood, driver's side). I sure hope they checked for a blown ECU-B2 fuse in the box on the passenger side under the hood. No master key always presents a problem. I agree that a Toyota Master locksmith might be able to provide the best advice.
 
The car comes with three keys. Two are master keys and the third is a valet key. The valet key can't make another master key. So if you lose one of the master key you should always make another spare master key. This will prevent you from getting in trouble if you lose the last master key. Learn how to make a master key if you want to save money. The dealer will take you to the bank when you lose all your master keys.
 
Can't seem to find it in the repair manual either?

I have the same problem with 2012 RAV4 Limited edition. both of my smart key stopped working and locksmith tried to reset the smart module and ended up losing both smart keys (which i could still use when tap on push button) but after the reset it didnt event start the car. went to Toyota dealership and they initially said need a new smart key that didn't work then got a new smart ECU that didnt work then they said its the NEW STEERING ACTUATOR ASSEMBLY got that and that didnt work. now they are saying it is the IMMOBLIZER MODULE. I have ordered the IMMOBLIZER MODULE and waiting if it will fix the remote programming issue,

How did you fix your problem what was the issue??

You definitely should have someone else look at it. They are just throwing parts at it.

Are you paying for all this things that weren't broken??
