[BiturboS4] S4 Stock Alarm - Upgrade

[Koutikas, Elias]

I've seen a couple of posts on other sites of how easy it is to bypass the
stock S4 alarm system.  I thought that all Audis come with an immobilizer
where only a specific key will work with your car because it sends a signal
to the engine.  I guess I have a couple of questions: 1) If this is true,
then how can this be easily bypassed? 2) Does anyone have any suggestions
for an aftermarket alarm system that will work with the stock alarm? I am
looking for these specific features: remote starter w/ manual transmission,
window roll up/down from remote, etc.  3) Does anyone know about PowerLock
or used it in their S4 and if so is it worth it?  Now I know that if a
professional thief wanted my car, they can get it.  I'm just trying to
prevent the common thug from stealing my car.  Thanks.
