Prius (2004-09) :: Hybrid Vehicle Immobilizer / Theft Deterrent Indicator Light Came On
Sep 9, 2015
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?

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.)

I have an 05 escape xls 4cyl that has started acting up in the past 2 weeks. The vehicle has 52k on the clock and has no other issues but what im posting about.
Heres the problem: Vehicle starts fine every time you turn the key. It does not stall or idle rough when engaging the trans mission so I've concluded it has nothing to do with the torque converter. Once the car is running the vehicle will shut off randomly with the THEFT light coming on. I played with it for about 2 hours and have found that it will do this idling in Park, while in Reverse, and while in drive. The vehicle also will shut off while I am going down the road and every time it does the THEFT light is coming on as the problem starts. It does appear that it only happens when the accelerator is not depressed and will sometimes stay running if you hit the Gas Pedal as soon as it starts to happen.
I have tried using another key figuring maybe a transponder is bad...No dice does the exact same thing. I have also noted that i do hear single quiet (tock) when the vehicle shuts off coming from the drivers side lower engine compartment.

2005 GX470.After returning home my wife parked the GX470 in the garage. She returned 30 minutes later and noticed the headlights were on. She also noticed the immoblizer light was blinking.
We always keep the headlights in the "auto" position. Headlights staying on is a little strange. but I recall the lights staying on once or twice before. Immoblizer light flashing has never happened.
I inserted the key and turned to start the car and the light went out and the GX started fine. Once I remove the key, the light starts blinking again. I tried this with both keys to make sure it wasn't a transponder issue--all keys did the same as above.
I checked battery voltage--12.4v. Charging--13.6v at idle Some light corrosion around the negative cable but not too bad. cleaned anyway Wife did say she came out of work and noticed that two different car alarms were going off that were right next to her car. Possible kids messing around. Maybe our car was going off as well?

I bought a new to me 2005. The car came with one fob with the silver logo. The smart key functionality does not work on the car. Lock and unlock works with the fob and I can start and drive with the fob inserted in the slot. Oddly when I push the black button on the outside of the door the red light flashes on the key fob. I have pressed the button under the steering wheel labeled key and that does not seem to change anything. Pressing the button on the door handle causes a long beep to sound.
In addition the light on the dash that is the car with the black key in the middle constantly flashes. It never turns off while driving. I believe this is the same light that acts as the theft deterrent light. I would think that the two are somehow related.

I let a friend drive my car for the first time today. Before today I always had a key with a slash through it that blinked until I started the car. Now that has disappeared and the hybrid lock indicator light is on instead. My friend left the car on, by mistake, while she went into the store. She tried repeatedly to lock it, and of course it wouldn't. Did this change something in my indicator lights?

Today I test drove the car and was told that the key fob was lost and a replacement was programmed for the car to start...but not locks. But while driving it I noted that the Immobilizer / Theft deterrent light was flashing. Is this normal because everything i'm reading says that the car shouldn't even start. I know that the car isn't stolen because we are planning to take over the loan in the morning for the car at the bank. What I should do. If this is because the key was only programmed without the original then can I simply use this one until I can have Toyota make me a new key for around 350-400 based on what I'm seeing online.
Below is the light that i'm referring to (car with key in it).

Just got a 2008. The Hybrid Battery Status indicator on the display is usually yellow. it will sometimes switch to blue. I assumed that yellow was the correct color but after reading some posts here it seems that they should be blue.

I have a 2008 Prius with 106,000+ miles on it. It was running fine till 2 days ago, I didn't start it yesterday and today when i went to start it, I get the Hybrid System Malfunction light, along with check engine, the red triangle and TPMS light. The gas engine tries to start up, then 1 second later makes a grinding noise and turns off.
I am in Toronto and its cold, but not THAT cold yet. So I am doubtful its temperature related. I checked the fluids and they all seem to be sufficient (engine oil, radiator fluid, power steering fluid). I didn't notice any leaks under the vehicle either.

On my way home from work tonight, the master warning light and the check engine (malfunction indicator lamp) appeared on the dashboard, and the hybrid system warning light has popped up on the multi-informational display.

I have a 2003 Ford Escape Limited V6 replaced thermostat and fuel pump and 3 coils and 3 spark plugs recently. Now the theft light has come on and will not crank or start. The fuel pump is still not working unless I manually press the fuse under the hood which is also the only way the car will crank still will not start. That's because the previous owner got the key stuck in the ignition so he bypassed it with a dial you can turn. The dial will put the car into ACC and on mode but will not get the car to crank. Also btn1 and btn2 fuses under the hood are draining my battery.

My "Theft" light on my 2005 Ford Escape is flashing and I cannot start the Escape.
1. I tried the key that I had been using successfully for the last 7 years. , car did not start, Theft light blinked. ,
2. Tried wife's dealer key, Car won't start, theft light blinks.
3. Tried various things, such as manual locking & unlocking, turning alarm beeping on/off, disconnecting battery, etc. Nothing works.
Called the dealer, they say they know nothing. Must bring car in, they say. Basically I am screwed and now must spend big bucks to take it the dealer because of Ford's software bug.

On my new/used 2008 Escape XLT 2.3L 2WD. It flashes every two seconds, like the manual says. Lower left corner of instrument cluster.
But I don't recall the warning light flashing when I test drove it. But I did push the buttons on the keyfob and various places on the dash/instrument cluster to see what they did...
Is the anti-theft system an on/off affair? If so, how do I turn it off?

My 2011 Camry LE 4-cyl has 48k miles. Today I was driving on the highway during very heavy rain. My vehicle slip indicator light came on, along with my check engine light. I stopped at Advanced Auto for a diagnostic check. They said they couldn't be sure if it was a sensor, or maybe a wiring issue.

2011 Sonata Se. Keyless fob will not unlock car or open trunk. Brake lights and overhead lights are all that will light. Immobilizer indicator flashes yellow when start button is pushed with brake depressed, car does not even attempt to start.
Putting fob in console will also cause the Immobilizer light to flash, no start up. Holding start button with foot on brake for a minute does nothing.
Owner's manual says call dealer. Car battery is 1 year old and 2 fobs have new batteries, and neither will work.

I have a Gen III Prius with 13,000 miles. It is less than a year old and I just got the Hybrid Malfunction indicator...I'm a bit upset about this and am wondering what it means. I'm not going to be able to take it into the dealership until next week, and was hoping to get some information about the indicator. It's a blurry shot but it is an exclamation mark with wavy lines below it.
