Starter Killer, How Safe it is?

I've been looking into the keypad based starter kill systems, and they're simple enough. The 103T has a neat little feature that makes it's backlit display the status LED for your system of choice.  It also has an overide feature for the dataports of DEI units for system control.

It seems like the general issues here that I can see from this thread is:

1) If you're doing the install yourself for your car or someone you know personally, YOU'LL know where everything is and how to teach yourself and/or your friend how to bypass it if doodie hits the fan. If you need to train a customer, give'em a cheat sheet or something to stuff in their wallet. DEI makes nice little cards for that most of the time.

2) They say you will never be able to stop a determined theif from stealing your car, regardless of breaking into it and taking everything that's inside and leaving the hull.  If you are worried about a thief getting under your dash or hood to start yanking wires, install custom shrouds to protect everything (This falls into the category of 'High Security Installs').

3) The only time I have seen relays go bad is if they are A) exposed to voltages outside their operating parameters, and B) are placed in environments where they are exposed to harsh weather elements, i.e. under the hood and not properly sealed, protected, etc.  I have had at least one relay go to hell on me, and it was mostly the socket that became corroded.

Nutshell: If you're not comfortable with the tips for bypass noted below, my answer is NO.

If it were /my/ car, and I was having a starter kill installed, I would request as a part of the install that the shop _TEACH_ me how to bypass it in an emergency; this bypass could be a five minute snap or a 15-30 minute additional cost in training or hidden switch, etc.

Granted, the new DEI Starter Kill systems have a 'Failsafe' name attached to them, but for the record I don't know what that implies. However, for my current Starter Kill, if my alarm starts going wacky, I have a few options for emergencies, I believe one was mentioned earlier:    

Pull brain main harness (most starter kills are active on power only)  -or-

Good luck.

So everybody says no to interrup/kill the ignition..................So what do you do when you are instaling the antihijack feature?  Almost every alarm today come with the antihijack feature.

Inclusive the Clifford Black Jack kills the ignition.
