Prius (2004-09) :: Theft Deterrent Going Off?
Mar 21, 2011
We have a 2004 Toyota Prius, with the smart entry and start system. A few days ago the (factory) theft deterrent alarm started going off at random, when there are no obvious causes. Last night it went off 3 times in the middle of the night. I won't have time to get it to a dealer in the next few days.
Is there a way to defeat the theft deterrent system and still have the car be drivable and lockable? Somebody suggested I could lubricate the door lock switches which may not be making good contact. Or, the fob battery may be low. (Can't check either till my wife gets home with the car.)

My 2005 prius with 81k on it just had the Hybrid vehicle immobilizer / Theft deterrent system indicator light spontaneously come on during a road trip where she was heavily loaded for the very first time since I have owned her for over 10 years. I stopped at a rest area and when I got back in it was on...immediately my batteries started draining. They are in 50wh mode which has never happened before, and charge will driving, but if I shut down for even a few minutes they are drained again. The dealer told me this was nothing to worry about and that as soon as they fully charged this would stop.

I have a 2012 Pruis C II which has a smart key and I just noticed that the Theft Deterrent indicator, page 110 in the owner's manual, has started to blink whenever the power is off. I have not noticed this in the past 5 months. Could it be that I never noticed it before or it has just started to work or?

Two days ago, my horn began honking for no reason...as if the anti theft alarm was going off. I was able to shut it off only by putting the key in its ignition. Last night, the possession by the devil was complete and at 10:30pm, my car began to honk (same as before) incessantly... and I wasn't able to turn it off. This happened about 5 time within 30 minutes. I tried to disconnect the battery but of course, the Prius designers placed the battery in a location that makes it impossible to disconnect. Why this horn malfunction is occurring?

...Battery is very weak also but had a couple questions...
I started by reading up on issue and 9 times out of 10 people were saying the fuel pump driver module causes the issue...
So I ordered a Dorman and plugged it in...I did not bolt it down...Just wanted to see if it would fix and nothing...
Now stuck on the starter...Top bolt is a huge nightmare.
Would a weak battery and bad starter cause theft light to flash or is my problem elsewhere?

Same symptoms as last time : [URL].....
I did notice that the theft light is not flashing this time. Truck acts as if its not in park. I have wiggled the shifter, and even tried to start it in neutral with no luck. Im really thinking that it has something to do with the anti theft/PATS system.

I just got an 08 F-150. No key fob and no power locks but it does have what appears to be an anti-theft device that blinks on the top of the dash. I would like to have keyless entry. What steps should I take?

I get these weird days when the Alarm system on the Phaeton would go off by itself. The car was locked and in my driveway when it decided to go crazy on me.

So in managed to spill orange juice all over the center console and bottom section of the radio.
I took the center console out and cleaned everything but the bottom radio buttons are sticking.
If I unplug the radio and take it apart will I have to visit the dealer for the code?
Is there a theft code?

2003 Taurus, 3.0 duratec flex, 30K. While driving at various speeds the theft light flashes for a split second and the car starts to stall before resuming normal operation on its own. The rpms drop off, and power is lost for a split second. This is getting more frequent and happened five times during a 30 mile drive. The original Ford key is being used. My scan tool reveals no codes. I understand that there may be anti-theft codes that my scanner cannot read.

I have a 2003 sliverado with a RDS radio. I had a bought another one from a person on ebay. I put it in and everything worked. the next day I went out to drive it and found the radio was lock up. Because of the anti theft on it. They did this to keep crooks from using the radio if they steal it. I read you have to have vin to unlock it without the scan tool. So I wanted to know how to use the old vin number to unlock it?

Yesterday everything was working great with my FOB key, I swapped plastic housing to one that is in better condition and then things went down hill. Both FOB's tested great for wireless transmitter. Old FOB no longer locks, unlocks or pops trunk. Car drives and turns over with master and valet keys properly (ruling out immobilizer I believe?)
I am trying to reset and program the FOB but my anti-theft system is not turning on with key- and that is critical to have on with what I have read here. Once I can get the red-light flashing and indicating anti-theft is on, I should be good to proceed.
Last night I turned key in car to on position and the alarm was going off, used the master key to pop the trunk open and that caused the alarm to cease.
Since then I can not get the anti-theft/alarm to activate at all. Currently if I have all my doors and windows closed along with the trunk, turning the key in door to the lock position it locks but does not activate the anti-theft -- no blinking red LED. Turning the key twice does not lock all doors either.

Last night someone broke into my 2000 Ford Ranger (3.0L, automatic, 2wd, extended cab) and tried to steal it from my driveway. For some reason they didn't complete the theft. Looks like they forced open the rear sliding window to gain entry. The steering column is damaged where you insert the key. The rotating part where you insert the key that has a slit is laying on the floorboard, along with a plastic ring that has stranded wire around it. (I think this is part of the anti-theft system that senses the smart key).
Anyway, I can insert the key and turn the ignition but nothing happens, the engine doesn't crank. The "theft" lite on the dash is flashing more quickly than normal. The thief didn't damage anything else but did take the owners manual from the glovebox. This is just an everyday truck that is over 10 years old, nothing special about it, so I guess it was an attempted joyriding incident. Police said they had another vehicle in the area stolen and later found abandoned. I need this truck to drive to work, what do I need to do to be able to start it? There's not a lot of money in our budget for bigtime repairs right now.

I have a 2000 Explorer Sport. Sometimes when I start it the "Theft" light stays on. If I kill the engine and restart the light goes out.
