Is a Chipped Key enough to prevent starting or do I need a starter kill?

[Rob 4092xx]

I travel to Mexico a lot where cars are stolen all the time.

I have the factory alarm in my 2009 H3.

I understand the 2009 H3 comes with a chipped ket that is suppossed to stop it from being able to be started even if the bad guys has a scanner and can get the codes from my remote control.

Can someone bypass this alarm and start my vehicle without the chipped key?

Is there anyway to bypass the chip key?

What about starter kills. Is this necessary or is my chipped key all I need?

Thanks!
