One of my cars is a 2008 Ford Crown Victoria Police Interceptor. Since it's a retired cop car, it doesn't have any anti-theft system, no chip keys/immobilizer, and there are various keys out there that can easily open/start my car. My friend found a random key in his Crown Vic ex-cop-car from a completely different department and even though the key is cut totally different it still opens and starts my car. I'm sure there are plenty of other keys out there that will work with my car as well, which is why I'm worried about it getting stolen.

I have a spare cheap phone (with like no resale value) on Xfinity Mobile, there are no line fees, so if I can stay under 100MB of data in a month it's free, or it'll cost me $12 for 1GB which is no problem.

Features I'm looking for are:
-Tracking ability
-Text me when the car is started.
-Text me when there is an impact with the car (using the accelerometer in the phone I guess?)

The tracking device is easy... just use Android Device Manager or Lookout or some other remote tracking app. The problem is the other two things... Not sure how I'd accomplish that honestly. I'm a web developer but I have no idea how to even start with Android app development...

Looking for input, hopefully someone on here could point me in the right direction. I've tried Googling/Binging but nothing I've found is even remotely similar to what I'm trying to do. Thanks in advance!

I was looking for the same thing. But all I found was OBD2 devices or some Chinese that used SMS for communication.
But after long time of searching I found ,,carlock,, it is OBD2 but it is using it only for power so you can use only OBD2 dummy for powering it. It has nice APP, using internet and it's not that expensive.

But if you found different solution let me know.

not a dev, but just wanted to comment on what Mato_xXx said about the chinese app that uses SMS.. if someone were to make an app, in some places (not sure if this is the case in China) data is more than SMS and vice versa.. and i know that those chinese made GPS car tracker devices work like this:

-uses GPS to record location
-checks every so often for location changes
-if location changes SMS gets sent to a number you pre-programmed into it every several seconds

these devices come with apps you can download to track the location of vehicle using google maps. Here is an example of said device:
(i am a new user and was unable to post links, but serach for "gps vehicle tracker" in google or serach amazon)

these things meet the criteria of your first requirement without the use of data (it instead uses SMS). If someone were to make a car security app, they should add this as a feature (location via SMS) because depending on what provider you are using you might run out of data or you could go over you data limit and amass a large bill... this would be an issue for people in Canada as we have some of the most expensive cell data in the world

I think what needs to be done is an app that can be installed where you can make it so the car wont start without some kind of authentication entered via your android device + the key..

what I think you were talking about when you said your friend found a key that would start your crown vic is the crown vic fleet key, which will start any crown vic (and usually the glove box and the trunk) ; (again, i am a new user,cannot post links, but serach google for "crown vic fleet key")

and because your vehicle is an old crown vic, its not going to have any wireless daig features so im assuming you'd have to buy some kind of hookup adapter for OBD2 to interface with your car.. but if you make any progress with this project please let us know..

this may be completely useless, but i stumbled upon this while looking for something completely unrelated: (gawd damn new user spam rules again! lol) www[dot]diagram[dot]com[dot]ua/english/articles/security-and-alarm-system-using-mobile-communication[dot]shtml
