It also really sux when you have to repair those security systems. I honestly would forgo the entire encryption fob thing in favor of a decent mechanical key for starting the car. Sure, they can be bypassed, but if someone is under your hood crossing wires then you have bigger problems.
Or better yet, an S&G digital safe lock. If it is good enough for missile launch codes it is good enough for my civic. Replacing an S&G lock body is far cheaper than any car immobilizer.

- brokenmachine 5y agoBetter than having the "more secure" number on a post-it on the side of the bomb. :-)
- irq-1 5y agoA digital keypad and a phone based system would be best. Apps can be updated for security, and the cars firmware can be updated via the app too. The keypad means even if a purse is stolen with the phone and keys in it, you can still start your car.
- dharmab 5y agoFord has keypad entry on a number of models, for example.
- meowster 5y agoIf someone wants to get in via the keypad, there is a list [0] that was mentioned on HN [1]. The list is 3129 numbers, which if pressed in sequence, will eventually open the door because all of the possible code permutations are contained in that sequence.

- Johnny555 5y agoIf they can't secure their own keyfob, I'd be worried that a phone app will open a remote vunerability. My car has an optional subscription that would let me unlock it with my phone -- I didn't sign up for that subscription, but I bet that it's active on the car's side and if there's a remote vulnerability, it's exploitable whether I've signed up for it or not.
- xur17 5y agoI stopped carrying my keyfob a few years ago, and just use the mechanical key - mainly because I hate how huge it is, but now I'm starting to think it was a good idea..
- Johnny555 5y agoI really like the convenience of keyless entry, I keep my key in my backpack and like being able to walk up to the car, have it automatically unlock when I grab the door handle, then I just get in and press "start", and it's ready to go. Then when I get to work, I just grab my backpack and walk away and I know the car will lock behind me. I don't want to move back to a physical key. That convenience shouldn't have to be traded for the huge vulnerability of allowing replay attacks.
- calvinmorrison 5y agoYeah, no. Key fobs are great. I wish I had them. My moms car unlocks the door if the key is in my pocket. Immensely useful while carrying bags and a decade old feature. Door keys suck. Ignition keys suck more. The worst is the middle years of both immobilizers and physical keys. Source: I can use 4 different keys to open 1 car right now. In fact, I only realized this after I locked my keys in the car and tried a few spares at the shop. A little jiggle and they all work
- sandworm101 5y agoFor doors, ya, but to start the engine i hate these new cars that dont have any mechanical key.
