Remote Car Starters: Security Vulnerability?

I am interested in a remote car starter. My vehicle is equipped with GM's Pass Key II System. Do remote starters disable Pass-Key? My ignition key does have a resistor of sort built into it. Is a remote started car "easier" to steal? Thanks I do not know much about this.
 
The RS does disable the security key system to get the vehicle started but the minute a thief thinks about stealing the car it would kill the cars engine.

The reason is because the R.S. system is hooked up to the brake switch and you have to step on the brake to shift it into gear and this causes the R.S. to kill the engine.

Also the steering is locked because there is no key in the ignition making it almost impossible for the thief to steel the vehicle.

Then you have the time-limit that the R.S. runs. Usually about 15 minutes or so, so they aren't going to get very far even if they are able to do all the things above.

Also in order for the car to be running via remote you as the owner have to be somewhere nearby to activate it. This is another deterrent for thieves because they want to avoid detection.

Nothing to worry about IMO.

I would not worry about it, on my car the immobilizer is only deactivated during the starting sequence, and reactivates after that car is started.

I installed the starter myself and before I programmed the keys I played with the system a bit. I sat in the car and started via remote, the car started fine, I then put my unprogrammed key in the ignition, turn it to ACC position and tried to drive off. The second I pressed the braked pedal my car shut off and sounded the alarm.

But you have to be careful, as some remote starters require a programmed key to be hidden in the dash to deactivate the system, these types of starters will deactivate the immobilizer permanently, so look for ones that have a programmed module for this purpose.

Even this is not a problem because as soon as the timer is up or you step on the brake the car dies, plus the ignition interlock is still locked.

I have this style in my SUV (Bull Dog) and I got an additional key from the dealer programmed for my truck and then I cut the metal key groove section off so it could only be used as a bypass unit and not an actual key, and put it in the box that reads and retransmits the transponder, as per the instructions. I buried the box well behind my dash so it would takes hours to get to by a thief.

I'm not worried at all and would love to see a thief try to steal my vehicle.
 
The outputs of the remote starter are +12v for ignition and +12v to start. Other modules will bypass stuff and the remote starter itself may have security features but as far as hotwiring goes just find those two wires, a manual on the internet, and you've got a running car.

Still need to bypass the steering lock and door locks, a lot of work. If you don't use the remote starter, noone would know you had one, security through obscurity.
 
I've had high end remote staters add to a couple of cars.
They lock the doors or they need the doors locked in order to work.
As above, they also only run for 12-15 minutes, touching the brakes kills the engine.
Yes they require a coded key, but as has been said, it's typically tucked way up behind the dash.
The newer cars that come with remote are the bomb though.
