Prius (2004-09) :: 2007 - Alarm Sounds Whenever Door Is Unlocked
Nov 19, 2010
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.

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?

Have started seeing an issue on my 2012 about few months already and the dealer could not even diagnose it because it is intermittent.
Sometimes when I arm the alarm, I can hear the actuators/solenoids cycle, but there is no single beep and the driver's door invariably remains unlocked. Repeated press of the arm button on the fob would not change, i.e. vehicle remains unarmed and driver's door remains unlocked. All the other doors are unaffected.
I can cycle through by pressing unlock once or twice, then the next relocking press would work. This is worrisome if I didn't pay attention to the beep and thought the vehicle is locked while in fact it was not, this could also happen when the vehicle is at the dealership as the porter would think pressing the button would have locked the vehicle.

As the title states, my alarm horn chirps when opening the unlocked passenger door in my '03 Golf. Asked the master tech about it and we sat there scratching our heads for a while. Nothing he's ever seen or heard before. What set of conditions would create this?

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

This morning when I shifted to drive mode, the door locks remained unlocked. When I parked the car and tried to lock by touching the door handle, it didn't lock. Then I tried using the hand remote and it didn't. Finally, I had to manually lock each door. 2010 ES350....

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?

The dealer was able to quite that beeping door unlock. Nothing bugs the neighbor more than my frequent in/out late at night.

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 rarely drive with anyone else in my 2004 Prius. This week we've had out-of-town guests, with two people in the back seat. When the doors are locked, the front seat passenger can pull on the handle to open the door, but the back seat passengers can't open their doors with the handle until someone in one of the front seats pushes the door unlock button. The child safety locks are not set. I keep getting out of my car and forgetting to push the button to let the back seat passengers open their doors. Is there anything I can do to change this rear door behavior?

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!

My 2009 LS 600h:
I park the car, i turn it off, the steering wheel goes to park position. Then, when i open the door i hear a sound like a electric motor.
My GS 450h did exactly the same. Auto handbrake on or off makes no difference.

I have a 2012 Santa Fe and the front map light fixture was where my issue started. I believe from what I read that the diode had gone bad because the map lights would work if the light button was pressed, but not if the door button was pressed. At that point, the only issue I had was the light now working when the door opened. So, I ordered a replacement part and tried to install it today. It was harder to get the old one out than last time, but it came out no worse for wear and I unplugged the old map light fixture. I plugged in the new one and it did not work at all. I checked the wire and it looked fine, the prongs and they were fine and tried it again... nothing.
Now, the back seat dome light and trunk dome light don't work either. (with the new map light plugged in or not) Old one back in and still nothing. Checked the manual for the fuse that is supposed to control those lights and it is fine. I got frustrated because it made no sense and gave up for the night. (no light is even plugged in where the map light goes for now) I come in the house and now every hour or two (when I lock the car) the alarm sounds for no reason. The alarm button won't shut it off either, I have to hit unlock and it stops. (3 times in the last 5 hours now) So, I have decided to leave it unlocked for now. So far, so good. BUT, I need to lock my car when I am out without the alarm sounding and I need my dome lights working. Everything else with / in the car seems to be normal.

2011 XLE, 54k on it. Drove to work last night, turn signals working fine. Came out in the morning, noticed the lights did not flash when I unlocked the door. Started up to drive home, noticed the turn signals not working, also emergency 4-ways not working. Found the 10 amp fuse, #19 blown, replaced, still no signals or 4-ways. Fuse is still good, I suspect to flasher/relay, but where is it?
Fuse panel under the dash mentions signals with clock & glove box light, but they are working and that fuse is good. I do have a hitch on the car with the electronic plug & play relay, but I unplugged that and plugged the stock harness back in, same problem, no turn signals or 4-ways.

Having some seemingly intermittent issues with my driver's door locking. I will use the key fob to lock the door, and the driver's door will remain unlocked. I have noticed this a few times, but haven't done many trial and error tests. I believe it does lock most of the time, but I forget to look since I'm at a distance when locking or unlocking typically.
I've read up on the solder joint cracking issue, and that's what I believe it may be. Are there any other thing to check on if that does not turn out to be the case?

So I was having a problem with my right rear door on my '99 Passat. Even when unlocked, I could not open it from the outside, just the inside. So today my dad decides to take a look at it and opens it (from the inside) and puts the child safety lock on... and closes the door. So now I can't get in through that door from either way.

Car is a UK 2004 W12.
I've tried everything I can think of or find to get them working but the interior lights won't come on automatically. They work if I turn them on manually, or once I'm in if I press the 'door open' button on the lights they will work when the doors are open.
But surely they should come on when the car is unlocked like every other car? It's getting quite annoying getting into a car in total darkness!

The rear door of my 1998 Sport will not open. It is unlocked and I can press the handle but the door will not open. I have been able to partially pull back the inside panel (not easy because the bottom of the panel is attached to the closed door) and it I can see the lock/unlock works okay and pressing the outside level works the rod to the latch connecting the door to the car body. But I cannot see where to pull the latch open and cannot locate any diagrams on the internet. I have sprayed some lubricant inside,, no effect. My thought is that if I can get the door open and remove the inside panel the repair may not be to complicated.

I have been noticing this problem more frequently. It's been about 2 months that I noticed the car is doing this.
I would typically touch the door handle to lock the car, (hear the beep) and sometimes I use the remote at a distance to make sure I did not forget to lock it. But after I return to the car, I usually go to the trunk, to put away my briefcase, (without pressing any button). After closing the trunk, and going to the driver side passenger door(its unlocked) (no beeping sound or anything)
I have made sure several times (clicking the button several times) that I indeed locked the car. but it's unlocked. I have tested the auto lock feature on my car (locking, then unlocking without opening doors, yes it automatically locks the doors after 60 seconds).

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?
