Default Cut-off (kill) switch

I have a 2016 and would like to put a cut-off (kill) switch hidden someplace that will prevent the car from starting. Has anyone successfully done this where if someone tries to start the vehicle without authorization it fails to start and then after the switch is turned back on there is no code in the check engine light or elsewhere? This would make a great theft deterrent. I was thinking of something that would effectively remove a fuse to either the fuel pump or something in the ignition.

Have you thought about a Soler Bluetooth Throttle Controller. It has a Valet setting where you can cut the operation of the throttle through your phone.

Looks like a decent set up but the last thing I want is to carry another fob with my existing keys. Just a hidden switch would suffice but what do I cut into to disable and not cause problems?

Just a thought!

A couple of decades ago, I had a disconnector on my Honda Del Sol. It was a plug-in. I disconnected it when I left the car.

It worked fine for a number of years. Then one time, on a very long trip, I stopped to get gas in a very small business offramp. I was about five hours into an eight hour drive, and it was about 20:30.

I got back into the car and it would not start. It had happened a couple of times before and jiggling the plug worked. The company that made it had gone out of business. This time it did not. I spent a long time, upside down under the dash, in very cold weather. I am still not sure how I got it started.

That was my last experience with a "Kill Switch",

One of my friends from our Corvette club helped me install the Solar Bluetooth Throttle Controller in my 2016 Stingray. I am awaiting shoulder surgery and could not have done it. Plus, he is excellent with cell phone technology. Not only does it have a setting that disables the throttle, but the performance upgrade is amazing!

If it is an occasionally used thing, I suppose you could rig a mechanical switch made to turn off the ground connection as is done with race cars. Of course doing so where I race I must have such mounted outside of the body somewhere (see pic) for easy/emergency access, but they could be in the rear at the battery on a street car. The issue then is do you want to finagle mounting the switch underneath somewhere/somehow or leave it inside at the rear and have to use the FOB's key to open the hatch every time you have it off and want to turn it on. Of course, on some C7s you'd only have to re-index the windows each time you turn on the power, which is not big deal. Or, find some other parking/storage options.

It is a pretty small fob.

If an illegal start is attempted, does it now require a code being cleared in the OBD? Where physically would this get placed? Under the hood or under the trunk floor? It does look like it may be small enough and I just may consider it.

With the Mobilistics, no codes are set if an illegal start is attempted.

That remote needs to be re-designed. Too easy to put it in valet mode when it's in your pocket. You have no idea it is in that mode until you try to start without pressing the remote. It's also very apparent to anyone looking at the fuse box to tell that isn't a stock relay. They should also re-design that to look like plain jane OEM GM relay.
I tried it & dumped it.

I agree the fob could have a sliding cover or other design to protect the buttons from mistakenly activating or deactivating it by mistake,


It's also very apparent to anyone looking at the fuse box to tell that isn't a stock relay. They should also re-design that to look like plain jane OEM GM relay.


Are you believing that a thief who can't get the vehicle started because this device is active will then open the hood and go directly to the fuse box and say HA HA this guys got a relay bypass and pull it out then install one he's carrying in his pocket ??
or even more crazy rifle through the interior looking for the OE relay that a owner may have stored in the glovebox??

IDK maybe i'm not giving the car thieves the credit for being that smart or prepared for any situation, just seems far fetched to me unless the thief is a professional Corvette only and knows the system.
You could also get a paint pen and color the top facing part of that relay to look like the rest so it blends in.
I've ordered this relay and feel its better than not.

No your not...... Car theft 101. If the car doesn't start & you have access to pop the trunk, hood & doors, you look for devices installed to prevent starting.
People that target corvettes or other specific cars have the tools, know the tricks. This is 2025. Heck I know tow truck guys that have a box of relay's sitting in the truck.
You can make it harder yes, layered approach is always good. The remote design is the main reason I returned it.

Ah ok good points I'm going to look for a club or brake pedal device and saw OBD lock device also, i guess that's the only way
to have a better chance with as you say a layered approach. also i have the dash VIN # covered with a black piece of thin plastic trimmed to fit over.

It's expensive, but Igla is what I installed for anti theft and OBD blocking. You put a 'code' in to start the car, and blocks OBD takeover. It won't stop a flatbed, but it's a kill switch...

After my well alarmed with kill switch guarded 911 was stolen off a surrounded drive way I’ve just accepted that if professional thieves want your car, they’ll get it
