Setting own pass-code seems to be in trend for most alarm system nowadays, whether it's keyless or the conventional remote alarm. And I feel that it's a good way to secure your car with the pass-code as even if the remote is duplicated, the thief still needs the pass-code to start the car.
The old alarm system works in a rather simpler way;
1. Press the unlock button.
2. Get in the car & start the car with the key.
In this case, the problem that thieves would be having is to start the car as the immobiliser is the one that disables the car. And I know there are thieves who actually have transmitter to transmit frequencies to unlock the car alarm. (I'm not sure how much that device costs, must be a lot. You can go to a locksmith and they usually have it.)
But this keyless system;
1. Be near your car while having the remote with you.
2. Press the button on the digital entry pad on your windscreen.
3. Start the car and drive off.
In this situation, the thief, if they can imitate the frequency that's used by your keypad, they can bypass your immobiliser as well as the way the system works is as long as the frequency/keypad is nearby, the immobiliser is disabled. So it's easier for the thief to start your car, right?
The digital entry pad is not optional to use by the owner, since we can have it control with our remote easily. The keypad is mainly built for your wife/gf/friend/mom/family convenient.
The keypad on the windscreen is wired connected, so no way it will transmit frequency.
Well then the thief have to imitate two frequency. The remote send only signals, while the main unit inside the vehicle only receive signals. If no one press the remote, no one can dupe the signal i guess?
Hacking RFID is very high tech thingy, especially hacking low frequency, and it takes time to generate the right frequency. Most alarm have delay if u press continuously, that is why the time gap slow down the theft. If u want to hack, i think u have to get very close to the car and holding up a duplicator with a cup of coffee.
Some high end model of Viper alarm comes with rolling code, but only the code will change itself when the owner press on the remote. What if the theft duplicate the code when you park your car in a shopping mall?? 30 minutes is good enough to dupe the code, since your code will only change when u press on the remote. Right?
Most of the high end alarm system comes with an rolling code, which means it will change the frequency in circulation for XXX times.
The system can accept up to three remote at once, to register them you need to setup in the digital keypad.

Added on June 27, 2011, 1:46 pmThat's the concern that Cavino brought up. So let's say you're standing near your car, maybe pumping petrol or talking to your friends and some snatch thief come up, open your door and steal your stuff. Snatch thieves, the things that they're after are usually handbags and notebooks, not the car itself. If you're pumping petrol, your engine would be off (Because the law says so and this is what you're supposed to do, not leave your ignition on when you're pumping petrol.).
If you're near the car with the remote, the doors still don't miraculously unlock itself unless you unlock it from the windscreen, am I rite? If not, it would be dangerous, especially for women drivers at parking lots as a thief/rapist may just jump behind the woman & conveniently drag her into the car without the need of unlocking the doors at all. Also, snatch thieves may just open the door & steal the handbag when she's pumping petrol/etc.
Nono.. You don't operate them with the digital keypad, it's not something the driver will oftenly used. It's built for your passenger convenient, you can cancel it by programming it too.
Once you have enter your car, start your engine and put the handbrake / foot on the brake the door will lock itself. If the door lock itself when the driver closed the door, what about the passenger? That time u will need to unlock the door again.. When you're pumping your petrol, most probably someone will stay near the door and some stay near the petrol filler.
This is how keyless works, it has advantage and disadvantage, for some car, when you locked the door, the fuel filler cap will lock itself too, then how to cope with this?
Nothing is perfect. That's the keyless advantage and disadvantage.

Mb he was doing Yoga.. The Kamasutra way...
No worries about speeding.. The moment i got my car i went for top speed testing and break in sessions (like the new style breaking in way) and went for dyno also.. All before 600km.. Then u change ur oil earlier a bit. Like say 850km..
Now this make sense to me to spend 2k on the product.. U could have listed this down earlier..

.
Btw whats cranking timer?
As for keyless go and u are worried of ur car signal being copied etc etc.. Just get a brake lock lah.. Even the fella can start ur car also doesnt means he can drive ur car.. And fyi eventhough this system will be able to bypass the ignition kill feature in the brake lock, it wont be much difference cos the brake lock ignition kill can already be disabled by just unplugging the y-socket and plugging the original socket back..
The most important thing when u want to prevent a car theft is to see the theft happening from the thief's point of view.. It doesnt matter how much of safety and precaution u take, how many steering wheel lock, brake lock, immobiliser, viper system etc etc.. If the thief says its jackable within 5mins, it can be done..
As for the fella copying ur remote unlocking signal, its widely available anywhere.. There are 2 ways to prevent ur car remote from working. One is using a frequency jammer, another is a frequency duplicator..
A jammer works like an EMP.. It blast out signals it detects, confusing the alarm, so caused ur car not able to lock due to confusing signals. u will then think ur alarm is spoilt or remote battery weak, and u proceed to manual lock ur car.. Bingo.. Just break glass discreetly and slowly hotwire ur car..
A frequency duplicator is what u see at those locksmiths.. they detect frequencies and store it.. Then when u are away from ur car, they just need to blast the frequencies out and the car will unlock by itself. Fyi high end cars come with descrambler codes to prevent the same frequency from being reused.. But i bet those in out car ones are using a predetermined scrambler code.. So all the thief need is another few persona keys, and they can owrk out the code for every cars and what kind of encryption its using. Still rmb the small metal dog tag thingy that came with ur car keys? it has an alphabet and numbers on it? thats ur code.. I get ur code and u are gg.com.my.
Hahaha.. i said the thing has not been finalize yet maa... where can show?
Cranking timer : some car / old car / diesel car / cars in cold weather need longer cranking time to start their engine. Some car have powerful starter and crank up the car easily, like my DMAX 1/2 crank already can get the cold engine started. Persona need 1 second to crank their cold state engine, warmed engine takes 0.4sec (i dunno why, maybe starter not powerful enough to crank up a cold engine.) Cranking timer is 0.3, 0.4, 0.6 and 1sec. I used 1 sec for my timer since sometime in cold weather really hard to start and CamPro has cut off feature. If in case your engine really hard to start / battery weak, you can press on the button for more than 4 second, that it will force start until the engine successfully cranked up.
Our CamPro comes with starter cut off when the engine has started, so don't worry your car will over crank.
What lock / alarm also useless lah if someone really want to steal your car. They would have bring a tow truck and tow your car away. What can you do? With chain locked to the wheel? They bring a chain cutter and will cut your chain in no time.
Should have gotten a mechanical shift lock, making them unable to shift out from P.
Brake lock? Drive slowly and make full use of handbrake lorrr
Jammer will absorb all the nearby frequency, making them unable to communicate.
Small metal tag? That one nothing to do with the code leh... All i need is place your key on a receiver for 3 sec and i will get your transponder code, that time baru gg.com.my
