Forgive my ignorance of electronics: wouldn’t a kill switch reset your date/time every time you used it? Obviously this and keeping the car is better than losing it to theft; but just curious.
I have the 12v solutions auto start that allows allows GPS tracking

Depends on how you implement it:

• A battery disconnect would reset everything! (I did find a heavy duty wireless relay that could work for this)
• Using a relay to disconnect the starter solenoid energizing wire = no, the starter just wouldn't engage
• Using a relay to disconnect the fuel pump = no, the car wouldn't start/run due to no fuel pressure

My car already has a fuel pump rewire on it so the above remote controlled relay seems like a quick and easy way to implement a kill switch

The 12v solutions works awesome, however it is so well known that I wouldn't count on it as it would only take a couple mins to disconnect/defeat it.

I think my strategy is going to be 'defense in depth' 2 or three systems to prevent a drive off and then one or more GPS systems to locate the car even if it is towed away.

yep agreed. Only limited to imagination and how intrusive you want to make it on yourself to start it.

Once I started hearing about key fob cloning, I went with one of these faraday pouches. They work, nothing gets out, and it's cheap insurance. Anytime I'm at a meet or show, in the pouch they go.

Might look into a kill switch with this going on. Only a matter of time until the technique used makes it's way over here. If they get past both of those, then they can have it. Insurance will take over from there.

Personally I would just but a hidden switch in the car that runs to the primary fuel pump fuse. It's just a simple fuse tap and a switch that once toggled off kills that circuit.

Another one stolen today in Dallas.

 

[JohnnyTSi]

oh Dang Sorry to hear! I wish you luck in a speedy recovery!

Some more clues though on how its being done! Someone on Facebook posted that replacing the BCM with one that has a matching fob is most likely how they accomplished the theft.

Some quick searching found this thread Interior electric control Module problem which seems to uphold the theory that swapping just the BCM and using the matching fob would start a GT-R.

The rest of the clues seem to uphold that theory as well. (the broken glass)

break window
open door
replace BCM
use matching key fob to start car and drive away.

The previous theory was that they were replacing the ECU!
If correct, this new theory really sucks as any custom ECU tune is retained and the car would run once started.

Theories on how they were taken? Given this is a public forum, I'd be careful about over-sharing personal configuration.

Fob Cloning, ECU swap or other?

John-

Fob Cloning. They tried to steal mine today and failed. The left the cloned fob in my dash. Broke my window to get in. I was parked in front of the gym.

 

[spdmn75]

Is this in Dallas also?

Damn sorry to hear. Glad they didn’t get it. Hopefully you have an agreed value policy.

Wow! - close call there! The broken window doesn't seem to fit the scenario of a cloned fob - Wouldn't they just unlock the car with the fob?

Is it possible to 'marry' a new fob to the car once inside (hence the broken window to gain entry)?

Yes. Downtown at the LA fitness off of Haskell

John-

Not sure, but it’s at the shop right now. I’ll let you know if any of the electrical components need replacing. As of right now my car does not recognize my key.

Time to get these cars hardwired with a kill switch.

 

[Guido]

This is really getting out of control. We really need to figure out a way to defeat whatever they are doing.

Time to get these cars hardwired with a kill switch.

Agreed, an alternate immobilizer is definitely needed! - I've found several options similar to this: https://www.amazon.com/dp/B09CTXDFKQ/?coliid=I11M6TP67TA9L8

Seem like a modern twist to the hard-wired kill switch, place this in-line with the Starter Solenoid energizing wire or the energizing circuit to the fuel pump relay and it would be very difficult to defeat - unlike a wired switch that could be found.

This option replaces a standard SPDT automotive relay and is almost a zero-effort solution to those of us with rewired fuel pumps.: NoStart Remote Controlled Intelligent Relay w/ Remote - Starter/Fuel Pump Immobilizer

My car already has a commercial GPS tracking system - I also placed a Smarttag AND an Airtag in different locations. Anyone swiping my property is going to get a very rude surprise!

All of these are inexpensive and easily implemented solutions.

What is a BCM?

 

[Guido]

Or I guess you could just take a starter fuse out of the fuse box everytime you leave you car. Low cost, but a pain in the butt. But you car isn't going anywhere without that fuse (whichever one it is).

Body Control Module - one of the computers on our cars.

That is one of my real concerns - Security vs Convenance! Make something that is too inconvenient and it won't get used!

[Guido]

I guess what matters is whether it will stop someone from stealing your car. A little inconvenience is worth it I would think.
