I have an unprogrammed key for my honda accord 2012, and not other key (they were stolen/thrown away by a dickhead trying to frick with me). How can I program it without shelling out to the dealership or some gay locksmith? I know electronics and some mechanics. It seems the ECU can be read from with the right circuit then inputted to the key so that is can start the car, but I'm also wondering if its possible to reprogram or read the master key from the CAN bus. Any thoughts or help?
>Any thoughts or help?
You're fricked.
>if its possible to reprogram or read the master key from the CAN bus
The rolling code seed doesn't hit the wire. It lives in the module. The module says "success/fail."
If you're capable of CAN bus hacking, just install your own device to with LoRA or whatever.
>You're fricked.
The master code is on the ecu. How am I fricked? That makes no sense. How do locksmiths get the code? Or do they just reset it?
>The rolling code seed doesn't hit the wire.
Makes sense
>If you're capable of CAN bus hacking, just install your own device to with LoRA or whatever.
To what end? Why would I need LoRa for this?
>How do locksmiths get the code?
They don't.
>Or do they just reset it?
Correct.
>To what end?
>Why would I need LoRa for this?
Do you want to open/remote start your car wirelessly without dealing with a locksmith or dealer or not?
I don't want to remote start the car(right now), I want the key to be programmed to the ECU to turn off the immobilizer. But either way, tell me about the LoRa method as well? I don't know much about CAN bus hacking, but it's that easier than taking the ECU out and resetting the codes then I'd like to learn.
I don't understand why you even made this post.
>easier
None of this is easy. You're talking CAN bus and ECUs. I clearly overestimated your abilities.
Give the locksmith his couple hundred bucks. And make sure you get *both* keys programmed.
>come to PrepHole

Get a real job homosexual?
It's DIY, not "ask a bunch of people to do it for you".
You are fricking braindead
No, for real. When you go ask a professor for help, you come prepared with questions, and answers for the questions that you think he might have.
On this board, any question to which the answer is a very strict procedure that requires experience and/or complicated, specialized tools is best answered by "figure it yourself" or "you'll pull your hair out trying to DIY it". Especially for topics where it is impossible to determine legitimate use from professional criminal activity.
>I swear it's my car
Sure.
>please do it for me, I will not compensate you
Frick you.
Further proving how braindead and new you are. You are not even remotely capable of answering the question, so why even post?
What question? How to program new keys? Frick you, that's how. You're a drain to this community's resources. You haven't shown an ounce of research or effort. Have you even tried looking up the service manual? It's all in there.
Yeah I've done a ton of research on ECU hacking and key reprogramming. I'm just asking people is they know things I don't. You are a genuine idiot who is not just unhelpful, totally incompetent, and unable to help in any way. Why even post in this thread? To comment on why I shouldn't do something I know is possible, and do the one thing I don't want to do and is the opposite to DOING IT YOURSELF? Are you are actually making the argument that me asking about alternatives from knowledgeable people about my goal is actually wasting imaginary resources and asking people to do it for me? How fricking stupid and pointless can you get?
Once again I am asking you to frick off.
Look into an immobilizer bypass if you are so poor but knowledgeable with your research on ECU hacking.
This is obviously part of me looking into it you useless dumbfrick. You've contributed absolutely nothing but shit flinging and irrelevant information yet keep talking about wasting time and "resources".
This is a good place to start if youre wondering about what ECU hacking is about. I'm basically just asking about easier ways to do this via can bus, which is exactly what a locksmith/dealership does afaia but for $150. This is a "controversial" topic because locksmiths want to gatekeep info so they can have their garbage profession.
Locksmith/dealers have the oem software and the encryption keys to donit the intended way.
They are encrypted on this end and you are not doing it without paying your manufacturer $
It's built into the oem software. You might pay $200/month for your oem software subscription. Adding a key is literally an extra charge you have to pay for. Like not cheap either. $75 or $125 you may feel like you're getting fricked by your dealer, but he's really not making a ton of gravy on that. It just goes all to the manufacturer.
All this encryption shit is why there's all this ecu hacking and special pogo harnesses and shit.
>They are encrypted on this end and you are not doing it without paying your manufacturer $
Some, but not all. I assume there are some ways to access the immobilizer via can bus that aren't perfectly encrypted. Manufacturers lie, frick up, and make insecure stuff all the time.
Yo, I don't care about this argument between you two.
Share some links for me to read about the topic.
Here another video basically explaining how most of the people in this thread are wrong, stupid, and don't belong on PrepHole

You sound like a wanker.
Hope the guy “trying to frick with you” throws this key away too.
>I clearly overestimated your abilities.
I think you overestimated you own. Youre not even clearly explaining why I would use LONG RANGE radio for something like this, which makes no sense.
>why I would
Because line if sight on the ground is a rare thing.
Because you can lock or start your car from aaaaaall the way inside the stadium in the cheap seats of you want.
Because why the frick not?
Why am I fricking starting my car from a stadium? I never said anything at all about remote start. Are you not understanding my post? I need to program my key to start my honda. Thats its. Put it in the ignition to start the car.
>Put it in the ignition to start the car.
So, you don't need the remote at all.
Well gosh golly that does save you both time and money!
Good for you. A shams you couldn't have realized that earlier. Could have saved so much time and discussion.
Thanks for coming by and happy driving!
You don't even seem to understand the op post.
All the procedures I've ever heard cannot pull codes from the ECU. You're supposed to fully reset the immobilizer codes, then put the car in programming mode, then you put your two or three or four or five keys in the ignition in succession and your keys are now programmed. Older systems are susceptible to key cloning but you still need the original key. Post ~2000 you can't really clone an existing key, but you can buy clones from a vendor, meaning that the system will recognize them as the same key.
For my 2009 Ford, as long as I have one of the two original keys, I can use those to program new keys.
But I need to have one of those keys to make new keys.
>and not other key
You don't have any original/master key?
Contact the Honda dealership.
All manufacturers have a different procedure when they do have a user procedure. With an OBD dongle a 15 minute wait period you can program fresh new keys in the system (Ford; don't know about Honda).
Honda doesn't have that.
Yeah, it was meant as a reply to the guy who mentioned Ford. I'm sure there are dongles for Honda too. I know that a lot of people will simply swap the ECM and just the ignition cylinder lock if they don't care about having a different key for the doors, like old school cars. In many models it is a lot simpler to reprogram the odometer if you care that much than it is to program fresh keys.
Try shoving it in the key hole and press the door lock/unlock button.
Gay locksmith here.
Stop being such a poor and spend the $50-$100 to get one of my fellow smiths to do it right and stop you from bricking your shitty honda.
