I just got a 2005 Prius with only one key. The key has always worked to start the car, but never worked to open the doors or set off the alarm. However, when I press a button on the key to try and open a door, the little red light turns on. Do I just need to replace the smartkey battery? Or is there something more complicated I need to do, like reset something?
View 17 Replies…well, I guess it just had to happen sooner or later! I was out running errands yesterday, and when I returned to my car, found that I was unable to unlock the doors, so I tried the buttons on the SmartKey FOB all to no avail, so ended up using the mechanical key to unlock the door, and placed the FOB in the slot in the dash. I checked the FOB battery when I got home, and found it to be slightly less than the 3.00V, plus the fact that it was quite cold yesterday, so that might have been a contributing factor. I've not needed to replace the FOB batteries in the 2 years I've owned the car.
View 3 RepliesI have a 2007 Prius with keyless entry and start fob. My battery went dead, got a jump, took it to Toyota dealer. They checked my battery and they said it is a good one just recharged for me. Then when I tried to start my car without inserting the key, it would not work. I asked the service person and he said I would have to come back and pay $110.00 for them to reprogram. Can I do this myself? It was working before my battery went dead. This happened once before but did not lose the keyless function.
View 5 RepliesI was out of town for about a week. I drive a 2008 Prius with about 35k miles and no previous issues. I get back tonight and go to open the door with keyless entry. Nothing, doors wont open. I hadn't replaced the batteries in the remote since I bought it, so I figured it was just that. I use the key to manually open the doors. I then go to start the car. Nothing. No lights, no noises, literally nothing happens. I figure, perhaps I left a light on while I was away and the 12V battery is drained. It is quite the rare thing, but it has happened a few times in the past. Usually I would catch it the next day and be ok, so maybe a light was on for a week and that did it.
So at this point I assume it's just a dead 12 V battery. I ask my friend to give me a jump. We open the hood, connect up the jumper cables in this order : + Prius, + and - to his battery, then - to the Prius frame. Quite a few sparks fly, which seemed like more than what I was used to seeing, but it doesn't seem too outrageous. I try to start the car and nothing happens. My friend then tells me he accidentally hooked up the jumper cables backwards. (I know now this is bad, and may be the source of the problem but hear the rest of the story to get a complete picture of what's going on).
So we swap them on his battery and try again. I put my foot on the break and push the power button. His car is still running in the background. The power button LED then turns green, and that is it. No noise or anything else. I then (while keeping my foot on the break still), push the power button again. This time the power button LED turns orange, the parking break P LED turns on green and the check engine light on the dash turns on. Also I think the car also makes the normal humming sound we are used to hearing when it turns on. No other lights are on at this point. The main display doesn't come on, nor does the interior lights work, or anything else for that matter.
The only thing functioning from inside are those 3 lights. I turn the car off and we just figure it needs more time to charge. So we give it a few more minutes of charging and still the same thing. We notice a strange thing. We hear a clicking sound coming from the fuse box area of the car. Every 5 seconds or so, it sounds like a relay clicks, and then clicks off after 2 seconds or so, and this continues on. My friends engine sounds as if during those two seconds like it is sending current to my car (lower engine rpm). So it sounds as if the relay sends current somewhere for a few seconds and then no current goes to my car, 5 seconds later it sends current to my car then 2 seconds later no current, etc. This goes on continuously and we are not sure why.
We figure maybe a fuse is blown. My friend checks the fuses we think to check but can't seems to find anything wrong there. We then think maybe the power needs to be disconnected to the electronics to allow capacitors and what not to discharge. So we disconnect the lug from the jumping terminal (the one we connected the + jumper cable under the hood) for about 10 minutes. We reconnect the lug back 10 minutes later and try again. Same things with the lights and buttons pushing as before. The only difference this time is you can get these lights to turn on without having the jumper cables connected (as if some of the battery was charged).
Next we figure, maybe we just need to hook directly to the 12V battery in the "trunk". So we connect to that. Now, instead of having the relay tripping every few seconds we don't hear the relay tripping at all. And the engine rmps are operating constantly as if it is consistently drawing current (constantly lower rmp sounds). So that is different this time than when we connected to the post under the hood. So we continue running the car at high rmps for a few minutes and try again. Still the exact same thing with the lights.
Also during these tests the break pedal seems to put pressure on itself when you hit the power button a second time and the lights turn on. (This is just a detail to include, I'm not sure if there is anything useful to gain from knowing this). Anyway, I know the problem is most likely that everything was fine until my friend accidentally hooked his end of the jumper cables to his battery. But in the event that there is something else I should check.
I have a problem with my prius 2004. When i start my prius then the Fan is always on with coolest temperature and air-con is also on. How I fix this problem? Is there any reset method to off the fan when I push on the power button or any method fan works with hot temperature.
View 4 RepliesI lost one of my SmartKeys I bought another (used)
Then came the rude awakening: Between reprogramming the SmartKey and a replacement metal key
Needless to say, I'm looking for a way to cut down on these amounts
I have prius 2007 of the Japanese make (140k miles). Yesterday, my keyless fob stopped working. I couldn't use it lock/unlock my car; however, it is starting the car just fine. I replaced the batteries on the fob but no avail. The small red light on the fob is shining like normal. There is no abnormal behavior in the car otherwise. What should I check?
View 8 RepliesI have a 2005 Prius. The remote keyless entry just stopped working for locking and unlocking the doors. I replaced the battery and it didn't affect it's performance. The key will still start the car without inserting it into the dashboard. It feels like the unlock portion of the remote is "stiff" and does not depress. It is toyota model number B31EG.
View 2 RepliesI noticed today that the red (panic) button cover is lost from my keyless entry (silver Toyota logo) Gen II 2008 remote.
What I basically need is a broken remote, essentially just that red rubber cover.
I have a 2005 Pruis and the remote entry does not work. Changed the battery in the remote and I still have to put the remote key in slot to start the car. Been working fine for ten years.
View 5 RepliesKeyless entry stopped working on driver's door, but still works on passenger door and hatch. Pushing the buttons still works. I already changed the battery in the fob, so it's obviously a problem with the sensor in the door handle.
View 5 RepliesI have a 2008 fully loaded Prius.
Keyless entry. it will not lock but pressing the black nubs or via either set keys. It some times beeps or does nothing.
I verified all doors are closed and there is no door open light on the dash. Every time I exit the car the car gives 3 beeps and the key light on the dash flashes.
I am owning 2008 Prius 2nd gen car since last may 2012, 2 days before when i was stooped and restarting he car my main display screen wont work and touch screen wont work either. after that i reset the car and kept it for 5 minutes. it works after the reset and went on to 260Km. today morning when i start the car same problem appears and cannot fix it like last time by during the resetting the system.
View 3 RepliesAll of a sudden, my 2008 prius, basic package without the smart entry system, stopped locking or opening the doors when i pressed the button.
At first i thought it must be a dead battery, so i replaced it with a new one and got the exact same behavior. i checked the old battery and it was still giving off 3 volts as was the new one when i checked that with a volt meter. when i press any of the buttons on the key, a small led light goes on and on the dashboard a picture of a key lights up briefly. the owner's manual does not show the key as a warning light.
I am wondering how does the jump start works on the Prius since it uses a electric motor to start the engine but not a conventional starter.I recently drained the 12V battery (left the interior lights on for two days) and had to take the battery out from the trunk to recharge it. Initially, I tried to jump start it at the specific jump port at the front of the car but it didn't have any effect at all. By that, I mean as if there was no external power source given to the Prius - i.e., no lights came on and no response when pressing the Start button.
I mean zero electric current at the Prius. Is the electronic starter motor power driven by the hybrid battery? If that is the case, it may explain why jump start didn't work in my case because it only passes the power to the 12V battery which doesn't drive the electric starter motor. So what good is the jump start for if it doesn't work like a conventional car? How this process works on Prius?
My girlfriend has a 2006 prius with two fobs, one fob works just fine opens/closes doors and red led illuminates, the other fob does not; I have replaced the cr 2032 battery, and verified that the battery works with a voltmeter. no battery energizes this fob as determined by depressing the membrane switches and NOT seeing any red led illumination. I could possibly fix the circuit if I could separate the two plastic housings.
View 8 RepliesAfter about a min once bluetooth connects it fails. In setup under bluetooth it says it's off and pushing it does nothing. My phone shows bluetooth on and still paired. If I was talking to someone call does not get dropped but I have to pick up my phone and turn off bluetooth so I can hear them on phone speaker.
View 5 Replies2006 Prius with 58,000 miles. Drive in San Diego and Palm Springs. Earlier this year, the A/C would just cut off, maybe about once a week. The control panel indicated the A/C should be on, but absolutely no function. Drive around for 20 minutes, and all of a sudden, it would come on and work perfectly. It is starting to happen on a daily basis now...sometimes it won't work from start, other times it just cuts out while driving. I can park the car and shut the car off with the A/C working, then come back 30 minutes, and no A/C. It doesn't seem to matter which setting is selected. The control panel accepts all commands, but no function changes when the A/C has shut itself off. Loose connection somewhere? It works about 90% of the time, and blows very cold. When it shuts itself off, no air passes through the vents at all.
View 6 RepliesI have a 2004 that I purchased in Jan '05 with just over 10K miles on it, after taking out a large deer with my previous Prius (90k miles on that one). I'm now at 271k and my first non-maintenance repair issue has occurred. My A/C was working fine one day, then nothing the next. Hot air, and nothing else. Had my regular service place (not dealer) check it during my regular oil change. Found the refrigerant was out, and did a little digging. They suspected a bad compressor, and referred me to the dealer. Upon recommendation from a friend, had another non-dealer check it the next day ( Wow, no Freon, and we can't locate the leak!). So I bit the bullet and took it to the dealer.
Not sure I want to put that much into fixing the a/c in a car this old/this many miles. I'm pretty handy with fixing things, but not this. And not a lot of non-dealer options in my area who will work on hybrids.
I have a 2005 Toyota Prius and the AC seems to work when the car is not warmed up. After about 5 to 10 minutes of driving the vehicle it does not seem to want to blow cold air. Obviously it works better in the morning then the afternoon but the AC seems to work intermittently. This may be electrical problem?
View 2 RepliesI have an 04 and the power door locks will not work. The hatch does lock and unlock but everything else just stares at me staring at it. When the fob or inside switches are used I can hear a relay clicking inside the Body Ecu / Fuse Box. I am thinking that is the problem as all fuses are good.
