Keys were just as vulnerable. Can we allow the owner/end user to replace the security system (that allows the car to start and the doors to unlock) to match the level they need/want? Currently, the car's engine control module (ECM) decides if the conditions are met to start the car. We need a standard socket across the industry that sends a TTL signal to the ECM to say "It's OK to start the engine if you want to." Yes, I said 0-5 V TTL because cars are like that. I will be very surprised if that TTL signal stays TTL and does not become a 12 V signal before this becomes a standard. The socketed security system has a second TTL output The socketed security system can read all CANBUS, but not write it. The socketed system needs to be where it can receive RF, but it must also be secure so it does not become easier to replace this socketed security system than it is to replace the ECM currently. Imagine realizing your daily driver can be easily stolen, so you replace the socketed security systems on your Dodge Ram, Ford Mustang, and Honda Accord so the same wireless key starts them all, and so they are all secure. Modules could be made that replace turn-key locks that support this standard to eliminate mechanical keys. Just a thought. One last thing, this standard must not have government-friendly backdoors.
