Prius (Gen 2) :: 2005 - Alarm Sounds Whenever Unlock The Car
Jul 29, 2012
I just bought a 2005 Prius in great condition. However, the alarm is making me crazy. It sounds whenever I unlock the car, whether by remote or keyless entry. I turned off the keyless entry function, but it still sounds when I press the unlock button on the remote. I have to press it again to get it to stop. It is very shocking, especially when using keyless entry. I walk up, stand for a moment to assure my key fob has communicated with the car, touch the door handle and it goes off! Then the car unlocks, I pull open the door and it stops. One day I was just walking by the car with my key in my purse and the alarm went off! I had to find the key in my purse and press the unlock button to turn it off. So strange!

I have a new to me 05 F350 dually with 6.0. When I open the door with the key the alarm goes off and the truck won't start. How do I shut this off so I can get in the truck with the key. I can't just leave the door unlocked all the time. It has the key less entry, but I have not set new numbers yet, and if I give the keys to a valet, I don't want to give them the door code too.

I bought the prius fog lights from and installed them per the instruction guide.
The lights work great but one BIG issue.
I cannot lock my car because after 3 seconds my alarm starts going off. Also whenever I start my car it chirps at me regardless if the alarm has gone off yet.
My car is currently on the road unlocked.

I'm a new Prius owner (<1 month) and have a hopefully easy problem to solve.

I bought a 2007 Prius this week and I am having trouble with the door lock/unlock procedure. I have read and re-read the manual and feel I am doing everything correctly. What is happening is I can lock the car, either with the push button on the handle or with the key fob. When I return to unlock the car 2 things may happen. Either I get within 2 feet of the car and the alarm goes off or I can get close enough to touch the door handle and then the alarm goes off. Either way, I then have to use the fob to turn off the alarm noise and then I can unlock the car. All rather embarrassing and I'm getting tired of looking like an idiot! The worst part is when I was back at the used car dealer briefly yesterday and went to show him the problem, it behaved perfectly which was the only time it worked ever for me. I have tried both of my key fobs and the same thing happens with both of them.

So I had my hood open to check my oil, not a big deal for a 2001 Jetta 1.8t. When I shut the hood, the car decided to simultaneously lock, and now the horn/alarm is going off and the key fob won't unlock the car or disable the alarm. And the keys don't work in the door/trunk so I can't get inside. What I should do?

My father recently purchased a 2012 Prius 3. To reduce his insurance premiums, he purchased an alarm system, which the dealer installed for him a few days after he first took the car off the lot. Now, when unlocking or locking the car from the driver's door handle sensor or via the remote, it both chirps (not the horn) and briefly sounds the horn twice or once, depending on whether you are unlocking or locking.
The problem is that when the car is unlocked from the trunk or the passenger door (using the door handle sensor with the key in pocket), this does not disarm the alarm, and the alarm will sound when the door is opened. The alarm is only disarmed when using the remote's unlock button or using the Smart Key sensor at the driver's door. One of the major differences between the 3 and 2 trims is that the 3 has Smart Key capability on the front doors and the trunk, rather than just the driver's door but the alarm has negated this benefit, as opening the trunk or passenger door without first unlocking from the driver's door or remote causes the alarm to sound.
Is this normal for a Toyota-installed alarm?

Over the past few days, my (factory) car alarm has started going off in the middle of the night, with no one/nothing near it to cause it to go off. The car battery is less than 9 months old, the doors, windows, hood and trunk are all always closed. Why it is happening?

I traded my 2005 prius a year and a half ago for an '08 which apparently was a rental car for 40K miles before me. It came with only one key(not a SKS)which recently quit unlocking the doors and hatch remotely. I looked under the steering column and there is only a reset button for the tire sensor guage, and a couple blanks, presumably one would be for the remote/smart key reset.
I am currently using the enclosed key to manually unlock the doors. The remote works as usual when I place it in the slot to start the car. I live an hour plus from the closest dealers, and would love to address this issue without having to go there. I checked the FOB battery and even replaced it, although the voltage was practically identical between the existing battery and a new one. The little red light is operational when i press lock/unlock. The car stays outside - i don't have a garage, and remains unlocked between trips. Recently it sat for several days in the last large snowstorm. When I finally drove it up the 1/3 mile driveway, it would not lock when i was ready to leave it up on the 'hard road'. I've checked out a few related threads, but haven't hit on this issue yet. Perhaps the 12V battery is weak?

On startup my 2005 Prius standard produces a low level cyclic noise which sounds like a hacksaw. This noise lasts for several minutes and is not affected by putting the car in motion or leaving it parked. The noise seems to be coming from the Synergy Unit but who knows?

My Lexus SC430 parking sensor alarm sounds intermittently while I am driving. (No, I do not tailgate the car in front.)
It has happened several times, all but once when it was raining. On that one occasion, the sun was shining. It happened again today while it was raining, and continued to sound after the rain had stopped, but the road was still wet.
What could be causing this to happen, and how can it be prevented. I have decided to fit an ON-OFF switch, if the problem cannot be solved conventionally.

I have found a new issue with my trunk. When I hit the release button the latch unlocks but when I set my alarm and then attempt to open the trunk it is still unlocked even after the alarm has been set!! The worst part is the alarm doesn't ever go off after I open it..

Seems to still go off for some reason when I unlock the door normally. The key will not stop the alarm as before. I have to pull the fuse to stop it.

For my '13 GLS, I leave my fob in the center dash box compartment, and lock the doors using the button on the door. Sometimes when I unlock the door w/my key, the alarm goes off. Why is that, and how can I prevent that w/out having to carry around my fob?

So my remote and main key got into a washing machine...Put new batteries in it but no go. Car does not start with either main key or valet. When I unlock the driver side door with either key, engine does not start and alarm goes off immediately. From searching the forums I assume I have 15 seconds from opening door and I am well within 15 seconds. Remote should not be necessary as transponder used to validating key is a passive RFID in the key part.
Dealership so far has been unuseful. I told them I can't start the car and they said yeah come in and we'll program you a new remote. When I got there (by motorcycle) they told me they need the car. It's a 2000 Passat GLX V6.

I bought a 2008 F250 crew cab, long box diesel and other than a couple of minor issues I love it. Tows my race trailer like it isn't even there.
If I use the remote to unlock the doors then everything works as it should, no alarm.
If I unlock the doors using the key pad the alarm sounds?
I have read thru many of the threads I can find but most are reprogramming the keypad. I am suspecting that a door open switch may be the culprit but wouldn't that affect the remote as well?

I've had a 2003 Rav4 for 10 years. Only recently did I discover that there is an alarm system in it. Occasionally, if you try to unlock the door with the key and turn it to the left, the alarm will sound. It goes off once you turn the key to the right to unlock the door. Thus far, it has never beeped when we lock the door.
This morning, for the first time ever the car began sounding 2 beeps when we manually unlocked the door and 1 beep when we lock it. (We don't have a fob) The alarm sounds if we open an unlocked door without first disabling it with the key. It is basically going off every time we try to get into the car. It is incredibly annoying.
What happened? What triggered the system to come out of hibernation? And how do we send it back to sleep?

I came out to get into my car today and pressed the keyfob to unlock and nothing. Went inside, same deal with my backup and valet key. I tried to scan with vag com with the alarm going off and I could link up, but not to the immobilizer or lock system. I did get both key 1 and key 2 adaptation surpassed codes. Even when I manually unlock the drivers door the alarm does not go off and I cannot roll up my windows with the key or unlock any other doors with the key. Things have been strange lately too, every time I lock the car and set the alarm the doors themselves locks don't sink down but the alarm is activated allowing anyone to get into the car but alarm goes off.

I have a 2009 VW JETTA. I have experienced my ABS alarm lights and sounds coming on in the past few months, twice while driving at speed in a curve and braking. Stopping the vehicle, turning it off and back on clears the errors, checking with my ODBII reader once I get home finds no errors.
Where this has occurred is a rather odd exit off of I-70 to Wadsworth Blvd., you are exiting at pretty good speed from the Interstate, curving to the right, then to the left and pretty much braking the entire time, and going into a slight bank. You can feel the increase in G's as you make this exit. I have also driven the exit and greatly reduced my speed and level of braking and the issue with the ABS does not occur. My local dealer is at a loss to find or explain what is occurring.
My questions are, is there something seriously wrong with my braking system (ABS), if there is, what is it, if there isn't, why does it do this only under the conditions that it is occurring?

My sons 2005 Santa Fe alarm goes off whenever it feels like it. Is there a solution to fix it or can the siren be disconnected without pulling the fuse? Could it be a hood switch problem?
