Prius (2010-12) :: Key Not Detected Signals - Loose Connection To Battery?
Nov 13, 2012
I changed the battery in my key fob recently. Since then the car has randomly given me "key not detected" signals. At these times, the door lock/unlock buttons don't work either.
When it does, I open it and push the battery around, trying to make it connect, close the fob back up, and it works for some apparently random amount of time. So my best guess it that there's a loose connection to the battery.
If so, have you found a cure, such as the right place to wedge in something small to make the connection secure? Anything else?

My husband was kindly pulling the Ex into the garage for me. I drove it around town today. He came in and He said he pulled it in and turned it off. Then went back to turn it on to pull it in a little farther. When he tried to restart it there was a big "CLICK" and it went all dead. He said the theft light briefly flashed after everything else went dead. Also, aux power such as cig lighters still work. Could it be a fuse?

VAD mobile scan sporadic connection. The camera would go in and out sometimes while backing like a loose connection. Now it does not operate at all. Is there a harness that travels through a hinged location? I'm going to rescan as soon as my Palm is charged.

I left the key on and drained my auxiliary battery(It was weak before) and when I jumped it it started and then shut off after ~20 seconds. I tried various different things and all I succeeded in doing was draining my HV battery from starting it so many times. So I disassembled the pack and recharged it and now it starts and runs but it is misfiring. It throwing 4 codes:
P0300: Random/Multiple Cylinder Misfire Detected
P0302: Cylinder 2 Misfire Detected
P0304: Cylinder 4 Misfire Detected
P1305: Ignition Coil 2 Primary Feedback Circuit
I inspected the igniters and plugs and they seem to be OK and I'm not sure where to look next. I'm not sure if the battery issue is related or not but I did replace the auxiliary battery.

I have a 2005 Prius Gen II with 114,000 miles on it. I was driving last week when it suddenly displayed a Christmas tree of lights that included VSC and the triangle of death....and of course the battery fan kicked into high gear.
Hooked it into a OBD II scanner:
P0A80 "Hybrid battery pack over temperature"
P3019 "battery block 7 becomes weak"
P3000 "DSL solenoid circut low"
P0300 "random misfire detected"
P000A "engine position system performance- bank 1"
Also C1241, C1242, c1249, c1259, c1310, c1357
I went ahead and cleared the codes. The angry lights went away but came back within minutes of driving. The car went into limp mode but I was able to make it home.

There have been a couple of incidents where the key fob has not been detected by the car, even though it is in the car. When it did this, I also noted the unlock button on the fob didn't work. It only does it a couple of times then all of a sudden it seems to work. There is no message for a low battery (it's not that old).

I was looking around under the hood and noticed a plastic T with two rubber hoses attached, and one end of the T open with no hose. This is on the drivers side in the engine compartment toward the fire wall. Why would this not have a hose on it or at least some type of filter?

I connected the driver's side LED door sill without a problem by following the video instructions. However, there were no instructions for the passenger side. So, I guessed that I would t-tap the two top wires. The LED's do not light up. Now on second view, the top cable that I t-tap'ed looks more black than blue. I should have done this in the light. So...
1) What are the correct wires to t-tap for the passenger side?
2) Did I damage anything if I t-tap'ed the wrong cable and I then remove the t-tap?

I have a 2011 Prius Three. After about a month of owning it, I had the dealer disable the back-up beeping so it only beeps once when backing. I'd like to disable the "key not detected" beep.

I got this message today, twice as I was pulling out of the driveway but it went away both times. After the 1st I stopped and pulled the key out of my purse. It came back on a 3rd time and right as I was trying to determine if it was significant enough to pullover when the hood flew up and hit the windshield. The hood was closed and there were no other messages.

I've had this happen twice now. I got my gen3 in October 09' and lately the car has said the key wasn't present though it was sitting on the passenger seat. I had to put the fob up to the start button just to get my car started.

After last maintenance at dealer where I got my Prius. I get two or three times of "Key not Detected" message per week when I try to start the car. I have to push start button several times for the car to detect key and start up properly. However, I don't have issue to unlock door by placing hand on the sensor and enter driver's seat. Where to start? I thought it was battery issue, but that wouldn't explain why I don't have any issue unlocking the driver door by placing hand on the sensor, which I always do before I push the start button.

Last week as I was returning home I had a strange event in my Prius. I was coasting at about 30 mph when I heard a very faint pop sound a bit like a balloon breaking. It sounded like it came from the right rear area of the car. Afterwards I thought I detected a very faint chemical smell. Could this have been something involving the HV battery?

B5 Passat, it has the 2.8 and it has been having moments of shuttering so I did a scan and hit 3 engine falts, I did do a clear and rescan so these are new faults.
3 Faults Found:
17801 - Ignition Coil Power Output 1
P1393 - 35-00 - Electrical Malfunction
17802 - Ignition Coil Power Output 2
P1394 - 35-00 - Electrical Malfunction
17803 - Ignition Coil Power Output 3
P1395 - 35-10 - Electrical Malfunction - Intermittent
Right now my guess is the coil pack is going out or loose connection to the coil, this coil is roughly 8 months old so it kinda has me at a loss and hoping its not the coil.
