I have a 2016 Camry with zero key fobs (I know, I know....long story). Dealership wants about $800 to reset computers and make new keys, but it looks like this guy has found a way to do it for about $12 and an hour or two of time (IF all goes to plan)

Can anyone confirm if this is roughly the same procedure on a Camry? I know it has a specific "Smart Key" module (this https://www.ebay.com/itm/363792812973)....so I would assume that's what the ignition communicates with for push-to-start? Then again, maybe that module is just for remote entry, alarm, etc. but the actual key security verification is done at the ECU, on that little DIP8 chip (like in the YouTube video)?

I've searched Google extensively to find out if this 93C56 chip (position IC900) resides on the 2016 Camry ECU, or "Smart Key" module, or somewhere else entirely....or if it's uses a different chip, whereby the youtube procedure won't work at all? Can't find anything.

Any insight or advice on this is GREATLY appreciated. Worst case, I'll have to have it towed to the dealer. Thanks!

With Toyotas, at the dealership there is a seed number, a master code that can unlock all of the computers to program brand new keys. Only dealers can do this, you apply for this online at the Toyota website with your service manager, and the computers can be unlocked for new keys to be programmed. This is expensive but it’s the only proper way to do it without backdoors from locksmiths or replacing all the computers that work the Smart Key Access System. Once the keys are programmed the information does get sent to the government in case someone steals the car. Here is a really good video talking about this:

Well that is absolutely stellar, spot-on advice! Thank you! I absolutely LOVE the Car Care Nut, and take what he says as The Holy Gospel.....so, to the dealership it is! Thanks again very much!

Well, when looking into this....there's this.


I'm not sure I'm brave/stupid enough to do this, but if you're really, really po' and got nothing else to lose, this might get ya there (might brick your ECU or other modules too).

You can check with an online dealer, and see if they can offer a better deal than a local walk-in.

For example, email their internet parts sales and ask:

What “government”? Federal, State, County, City/Town? Anything official from either “the government” or Toyota to back that up?

The video I linked above was from the Car Care Nut, he stated it in the video. He was a Master Diagnostic Technician who is very well respected, that’s who I got that from

Well it turns out it's getting more complicated (imagine that). To elaborate a bit on the "long story" part, the previous owner really did a number on this thing. Apparently the engine was replaced after it was hydro-locked going through water, when this was done, the ECU was also replaced for some reason (???why???). Apparently the dealership programmed several keys that kept getting lost. They eventually quoted $4,000 to have all the computers involved in the immobilizer/smart key handshake process replaced. Apparently this involves removing the engine to access one of the computers (????)....I have no idea why this would be the case. I called the dealership and am waiting on a callback from one of the main folks who was dealing with this originally. It sounds like the previous owner may be confused about what was happening (she's admittedly not a car person, at all, not even a little bit).

I found a perfect matching donor/parts vehicle locally with matching keyfob, ECU, smart key module, and immobilizer module for about $800. It seems like that would do the trick (as long as there isn't some other module that also needs to match? Door lock module? Body control module?).....but this whole "removing the engine to access something" that was apparently quoted previously has got me worried. Hopefully the dealership will be able to put that to rest either way.

Can anyone confirm if these are the only modules involved in the SEED/immobilizer/smart key handshake process?

- Key fob
- ECU
- Smart Key Module (89990-21010)
- Immobilizer Control Module (89784-21010 B2)

Part #'s are actually for a Scion tC, which is the actual vehicle I have. Just figured I'd get more support in the Camry section here (bigger community, better knowledge base)....they're effectively the same vehicle mechanically/electrically speaking.

Maybe they meant removing the dash, not the engine. There are computers under there, and accessing some of them is a huge job.

That could be. I know for my Land Cruiser, to access the SRS module, the FSM says you need to pull the ENTIRE dash (not just trim), the steering column, and the entire AC system (which involves discharging/recharging) just to access the module. I was able to do it in about an hour by just removing a few panels and accessing the bolts with an extra long handle ratchet.....still, they're going to follow their procedure in the FSM, or at least bill accordingly.

Maybe I need to get an FSM for the 2016 Scion TC and see what it has to say about all this. Still waiting on a callback from dealership.

Yes, the entire dash might have to be removed all the way to the firewall, depending on which computers need to be changed. eg. there is the "ID" computer which is right up against the firewall, behind the HVAC box. Not saying that needs to be done in your case.

I’d consult a local locksmith before going that route, they have ways of doing things that the dealerships sometimes will not. I’ve seen several threads of members getting a local locksmith to replace/program keys that the dealership said couldn’t be done, just my 2 cents. There are ways for them to reseed those modules.

To add on to this, please make sure that it’s a very good locksmith that is willing to pay for anything that they may mess up. One small mistake and they’ll lock up the computers and then go ghost and you’ll never reach them again; so make sure it’s a VERY good locksmith. That’s if they do it, you have to call around.

You nailed it, that's exactly it. The dealership is saying the ID code box isn't responding, so it's likely defective and should be replaced....which is a 10 hour job. But they've already replaced the smart key and immobilizer modules with different ones (not sure why....seems like they should've just been kept the stock ones, reset and reprogrammed like everyone is suggesting).

Talking to the local service advisor at the dealership that's been doing the work on this thing, I get the feeling he doesn't really know how these systems work and is just shotgunning parts the second they hit a roadblock or Tech Stream doesn't behave exactly like the FSM says it should (if they're even following the FSM). He wasn't even able to say for sure which modules are involved....so they might tear the dash apart, put it all back together, and THEN find they missed something and it still doesn't work after a $4k bill. Might try calling a different dealership or really super pro locksmith....don't really have much confidence in these folks at the local dealership.

I have been told that the computer can be programmed with a MAXIMUM of 10 keys. Once ALL 10 blocks are filled, there is nothing that can be done with the module. The program blocks can not be reprogrammed once used

Where did you hear that? Clearly there's an upper limit to the max # of keys that can be stored at any one time, but those blocks can always be cleared out. Otherwise, when you buy a used car and want new keys so the previous owner doesn't have keys to your vehicle, there'd be no way to clear out the old keys. This guy does exactly this:

He also says the same process can be done with Tech Stream (assuming everything is working correctly, which doesn't seem to be the case in my scenario).

This isn't exactly the same but: I bought a used truck from the local Toyota dealer. It only had one key. They sent me to a local lock smith for a second key. They lock smith said they do all of Toyota's work.
