In this question, the OP wants to bypass their car security system.
We have no way of telling whether they are the actual owner or not.
How should we handle such questions?
I don't have a problem answering these questions or having them on the site. The information is available in the service manual, and most of the time takes special tools, sometimes dealer specific tools to work on these system. Most all of the systems have some sort of time delay so that the procedure is never fast. Most thieves aren't going to wait around for the 10 minute wait that Ford requires for access to the security module even with a Ford dealer scan tool.
I recently had to replace the BCM on an older dodge caravan, the replacement (recycled) BCM was for a vehicle with a security system, the car it was going in was not. There was not an option to reprogram the recycled BCM, once the security module is turned on it cannot be turned off. I simply added the required wiring and drivers door switch to allow the owner to disarm the security system.
Again I don't have a problem with these type of questions being asked and answered here.
I'm also a programmer and spend some time around other parts of Stack Exchange. I'd to bring some outside insight to this question.
Is there a legitimate (legal) use of this knowledge? If so, I think it should be allowed. In the software world, there are a lot of gray areas where an answer to a question could be used for nefarious purposes. However, that same answer could help someone to make a system more secure, or simply work around a real problem that they need to hack around (jerry-rig). We have no idea what a poster's intentions are. Unless there is no legitimate use for a piece of knowledge, or we're entirely certain OP is up to something illegal, there's no reason to close the question.
That said, if you don't feel comfortable sharing knowledge with someone because you're afraid of what they'll do with it, then don't. No one is under any obligation to answer any question ever. Please don't ever put yourself in a situation where you would feel guilty for answering someone's question for
fake imaginary internet points.
I'd say not to give any details on how to do so - even if the OP is legit, other people reading the page might not be...
Refer them to their local dealer?
Perhaps we should have a specific rule in the site - "Questions about bypassing security systems are off-topic as they could be used for illegal means"
