on honda's ive had no problem with just using a well worn key and jiggling it a little.....
accidently switched key's on two honda's we were working on at harry's...didnt know about it till the 2nd owner said those werent his key's.....after that i tried it a few more times and id say it worked more than half the time unlocking the doors and starting it...
this shit is one reason jamie is having me fully integrate his antitheft shit into his mustangs harness with multiple imobilizers....he's still gonna have to remember to turn the steering wheel all the way to the lock every time he parks though to prevent a wheel lift/flatbed towNgo.
That's why I wont kill the VATS on the TA.... its just one more thing they'd have to get thru. That and I always have it torn apart in the garage anyways!
thats easy, 50hz ground pulsed signal box with 3 wires-1 on a certain pin of the pcm...done
or they can just power on IGN V and reflash it right there.
nothing is fullproof, the best you can do is have enough layers of security that it'll take em too long to break through and drive it off....thats when they come back with a wrecker usually
