What an alarm does
An alarm makes noise and light and draws attention. It also deters. It can be tripped by a nearby impact or by an actual attempt.
What a kill switch does
A kill switch quietly stops the engine from starting. It makes no noise, so a thief may spend minutes trying before giving up.
Which fits you
If you park in busy areas where noise draws help, an alarm shines. If you park in remote spots where no one hears, a kill switch and tracking do more.
Why both
Noise discourages and the barrier stops. Together they cover more situations. Many Viper systems already include a starter interrupt, so you get both in one.
A tale of two parking lots
On a busy street, an alarm draws attention and usually ends the attempt. In a quiet lot where no one is nearby, a kill switch quietly turns the attempt into a failure. Owners who park in both places do well with both.
Quick answers
