Or rather 3106th guess.
My math is off since I’m not used to working with base 5 number systems. It would be the 3116th guess. Sorry for all the posts but I can’t stand leaving my mistakes uncorrected.
I use 6 digits that require each of the 5 buttons to be pushed and they have nothing to do with a birthday.
Yeah, the bad keypad got me good. It was replaced under warranty. A short in the sucker made the interior lights dim on and off, over and over, without ever stopping. It sucks begging for a jump on a “modern,” “top of the line” type of car. Especially in the parking lot where employees that make the thing are the one’s being asked for a jump.
That’s assuming a thief would actually be taking the time to press the buttons.
But most of these locks also work with a wireless radio transmission, where a circuit on your keyring transmits the codes to unlock the car. I don’t think it would take much for a professional thief to create a small transmitter that goes thru all the possible combinations in a short time. They could be transmitted at electronic speed, much faster than physically pressing the buttons. Such a device would certainly be worth the cost to a professional auto-theft gang. I wonder how long before they start using such devices?
IIRC, they’re using “sniffers” which capture the code as it’s transmitted by the keyfob of the owner. No need to crack the code, since you’re basically making a recording of the code’s transmission and playing it back later.
You can forget about using a sniffer. The receiver expects a certain digital code to be sent, and that code is determined by the last code used with an algorithm applied to it using a random number which varies from receiver to receiver. I won’t say it’s impossible to figure out if enough codes are listened to, but it’s definitely not technology your average car thief would possess.
Why would a thief bother with the keypad? All the keypad really does is unlcock the door, so why not use something quick and effective, like a slim-jim, a lock-pick gun, or a rock? I’ve seen relatively untrained police open a door with a slim-jim in about 30 seconds, and a locksmith unlock my car door with a lock-pick gun in about 5 seconds. A rock through the window, while crude, is effective and almost as quick. Each of these could be done in less time than punching in a handful of combinations.
