2017 Prius Prime Factory Alarm

I might be wrong, but I don't remember PP having an anti-break-in security alarm other than a manual Panic button on your fob.

 

Never had one installed on any of my cars. I think many remote engine starter fobs and telemetric can function as a security alarm and remote locator, but how good they are in terms of theft deterrent, I have no idea.

 

When I got my 2017 plus, there was a glass breakage alarm offered by Toyota as an option. I almost got it but the dealer talked me into a Karr alarm system instead.

 

One minute might not be long enough to wait.
Do you have an owners manual ??

You need to be careful with after-market alarms.
You can easily run the 12 V battery down......so that YOU can't get in either.
Or when you do, it won't run.

 

If your simply looking for a solution to deter catalytic converter thieves; a simple remote motorcycle/moped alarm should do the trick (around $15). They run the gambit; one piece w/self contained battery, to alarm style units. I opted for the alarm style modular unit w/9V battery backup; tossed the wimpy alarm horn and wired directly to my car's horn relay. It's another FOB on your key chain, but it works. No battery drain issues, since it was designed to draw off of a small motorcycle battery and I know how to properly install alarms.
About 8 years ago, my girlfriend had her car broken into at her apartment complex. The amateur car thieves / wannabe hoodlums mangled her ignition switch and settled on taking the dollar and change out of her ash tray. I replaced switch and re-keyed the car - installed one of these units. She didn't have anymore issues, other than the neighbor directly in front of her assign parking space telling her the alarm went off - once in a while. So I guess it's doing the job and money well spent.

 

This is what I installed:

There's also a self-contained unit, under similar items, that'll literally take you a minute to install. the problem with this unit is that you'll have to change the battery every 3 - 6 months. Depending how often you use it and how often it goes off. Make sure you point the alarm horn down, so the sound will resonate.

 

Check out fortin.ca - they make alarm/remote start units that require little to no wiring (t-harness install). They plug and play and use the factory data bus to catch the door/trunk/hood opening and you can expand their basic kits with either RF kits that give you a 2 way remote that will notify you if alarm is triggered, or even cell phone options. They've been my goto for remote starts for years.
