Hi,

I have a TH with factory alarm and keyless entry. What is the best way to upgrade the alarm with maybe shock sensors etc? Is there any upgrade kits available out there?

Cheers

You'd have to go aftermarket.

i bought a Rhino RA car alarm for mine but not sure if i got the right 1 ... retails for $495 but still asking around if i got the right one

if not i am willing to sell for around 200 if anyone is interested
