Thanks
@fx_chip and
@jayceegee for the replies. After thinking about it a little further, I don't think I am going to do this. Not really going to stop anything from happening, a different alarm will just make me aware of it sooner.
I personally have a pager alert and tracking system on all my vehicles. The disadvantage is if you are far away a smash and grab cannot be prevented or attended to. I also have various safeguards that prevent my vehicles from being started even with a key or fob.
Good news is the hidden cameras catch them in the act. Bad news is (in the US) most smash and grabs and grand theft felonies are treated as a misdemeanor. What I mean by that is even if your vehicle is recovered and the perp is caught there is not much that can be done to put them behind bars or get compensation.
All my tracking devices are all hidden and pretty much foolproof until the vehicle crosses the border. As anyone knows, once a vehicle gets into Mexico or Canada you are on your own if you want it back.
Best to keep your insurance up to date rather than buying a noise maker -- IMO.
100% this!! I also pay a little extra and very high deductable for my insurance to get full replacement value including accessories installed.
Something to note is no matter what you install or lock up a desperate criminal will figure out how to steal it.
