How to disable Car Alarm on prius 2004

There is a button below the steering wheel to the left of the SKS disable button (if your car is SKS) that will disable the interior sensor but that is likely of no help. It is so you can lock the car with your dog (for example) inside, and the dog's movement will not set off the alarm.

In regards to the USB/Aux audio accessory, stranger things have happened and that is a possibility. The fact you can't remember whether the alarm activated or not before installing that doesn't help.

You could always just lock the car with the physical key, that will not set the alarm. If you do opt for this, you could get a key cut on a standard Toyota blank so that you can have that on your keyring. Then you will not need to remove the little key from the fob all the time and it will be easier to lock/unlock having the more standard-sized head on the key. If you do do this, you will not be able to set the double-lock – but it sounds like security is not your top priority in all this.

That's all I got.

PS, by design, I don't think you can disable the factory alarm. You would need to look at doing something a bit more unorthodox more than likely if you want to pursue this avenue.

 

Assuming you have a factory installed alarm, you should be able to disable it from within any version of techstream.

Not sure if an App like Carista could do such, but it may be possible.

 

That would be interesting, I'm all ears.

 

Correct. You have to turn the alarm off first by using the remote to unlock the car. Once the alarm is off, you can use the physical key to lock it and subsequently unlock it.

Correct.

 

If you need another bluetooth scanner be sure to review this webpage first : Hybrid battery diagnostic and repair tool for Toyota and Lexus

Was the purchased mini-vci cable listed as containing a CD, or a weblink to the above required application?

Which device and OS version were you looking to install techstream on?

 

This blog is always a great resource, be sure to look at the various tags, like toyota-techstream and mini-vci

 

It depends on which car you have.

Gen 2 never offered those features.

 

I have a bandaid solution.

First I tried replacing the batteries in my fob, that wasn't the problem. then I tried locking the car with the physical key. that didn't disable the security. I finally got frustrated and called my local Toyota dealership. they were no help at all.

I finally had the idea to see if the horn had a single fuse. it did. look up the fuse for your horn and pull it out. The bad news: you won't have a horn. The good news: you won't have a horn.

 

Sorry for necromancing 4 years old thread but just got exactly same issue as OP.

Maybe US model is using the normal horn only but UK model does have 3 horns, one for security mounted to the firewall on engine side, it is connected to main body ECU directly without any fuse, and 2 (low and high tone) operated from the steering wheel and alarm (use normal horns for alarm can be disabled). So removing the horn fuse don't kill security horn.
