Prius (2004-09) :: Transmission P Lock Mechanism Is Abnormal
Mar 20, 2011
I own a 2005 prius that I purchased used this year. This morning I had my first issue. I turned on the car and it gave me the following error message:
"Transmission p lock mechanism is abnormal. Park your car in a flat place and apply parking brake completely."
The parking break wasn't on and I was already parked in a basically flat parking space. I couldn't move my car because it wouldn't go into drive or reverse or neutral. (The car turned on, but the engine wouldn't start). I tried turning the car off, but the car also wouldn't turn off. I let the car sit for 5 minutes then tried again and the car turned off. When it turned back on, everything was fine.
My questions is: Do I need to bring this into a mechanic? The car seems to work fine now, but I don't want to be stranded again or do damage to the car by driving it with an issue.

My 2005 Prius has about 140,000 miles. I had been getting the intermittent warning message, "Caution: The transmission lock mechanism is abnormal" although the vehicle has been able to start and drive just fine. I replaced the 12v battery, which was suggested in several other threads. However, the warning keeps reappearing. Possibly related, my gear shift knob is "sticky". I'm able to get it into each gear (and the transmission remains in the gear selected), but the knob does not move smoothly like it used to.

After trying to start my '08 Prius, the following message appears on my touch screen about 2-3 times a month: "The transmission PARK lock mechanism is abnormal. Park your car at a flat place and apply the parking brake completely". I try to patiently wait it out while I apply the parking brake, unapply it etc. Finally, all dash lights will go out, and I can then start the car.

A month or two ago I started getting the error message on my screen while driving. There is a problem with the Transmission P lock mechanism. Park you car on a flat surface and fully apply the parking brake. After reading up on the error, I replaced the 12-volt battery. (it was the original)

My 2011 Prius apparently had a broken lock actuator on the driver's door, and knowing that the dealer would charge me over $500 for installation of a new actuator, I decided to order a new $5 motor off of ebay, and change the little motor inside the actuator myself. Everything was going fine until I put everything back together, and gave it a try. Now my door won't unlock at all. All of the other doors work fine. I've tried the little key from the keyfob, and turning it kinda feels mushy. My guess is that something is wrong with my re-installation of the cables.

Weird problems with my 2006 prius. Car has 54,000 miles.
4 times now over the last year, during abnormal braking conditions (someone swerves over at me on highway and I have to break and swerve suddenly to avoid), I get multiple warning lights, and the warning buzzer. Yesterday this happened, and I got the red triangle, the red brake light, the abs light, and two new lights on the LCD display I've never seen before. I pulled over and began to slow down. The brakes felt stiff, and the vehicle started to loose acceleration power. LCD started resetting itself. I stopped the car, turned it off, and turned it back on to find everything normal. I then drove 200+ miles to my destination without incident.
This is the worst case of this problem yet. My 12v battery was replaced last year after the first of these issues, with similar symptoms, but no loss of acceleration. The tech said the only code in the system was a voltage spike, and thus thought it needed a new battery. In every other case of the problem, I turn the car off and turn it back on, and it's fine. I'm about to drive 2000 miles next week, and want to avoid further issues...

Although the key slides into the lock easily, it's a bear to turn the key left and right. I tried squirting some graphite into the key hole and working it with the key but that didn't do much if anything.
Is there a way to lube the internals that a homeowner--not mechanic--can do?

I have a persistent prob with the lock mechanism on the rear door of my mk4 golf, I don't suppose there is a picture tutorial on this subject. I have looked but can only find for the front door.

My car occasionally locks me out! When I lock the car using the driver's side automatic lock, it works fine, but then it won't let me back in. My repair shop says the left-side locking mechanism needs to be replaced but they can't get the part. The car is a 1992 Cadillac Brougham that I've had since new. The car is in great shape and runs like a top.

Ok. So I purchased my 2009 Prius on Saturday (4/23/2016). Couldn't be happier. I have a couple of things that I need to get to right away including a very small crack on the front windshield and the slide mechanism on the drivers side. I am a small guy and the seat belt currently goes across my lower neck (not a good thing). Now the passenger side will allow for the adjustment of the seatbelt height by sliding up and down but the drivers side won't budge. The seat belt itself works fine, just not the adjustment for changing the height.

I've read around the forums stating the P Lock error is common from a low battery causing the vehicle not to start.
The strange thing is that my vehicle DOES start and the message appears and the dash shows READY and I am able to enter gear and drive. If I hit a button on the console the message goes away and if I'm driving at higher speeds the message does not return but the large triangle stays. The error message only reappears when I slow down to 3 mph.
The error does flash back on the screen when I slow down to stop or sit at a light. The car does not shut off during this it just flashes the message and shows the large triangle.
My battery test shows 12.3v on no load and 11.6 on a load. I would hate to replace my battery and have the issue not be resolved.

Can I disable the automatic door lock mechanism? Maybe pull a fuse? All of a sudden the locks start locking and unlocking over and over and the lights dim. I would like to disable the automatic and use the key to lock and unlock the doors. It is a 2002, F-250-Super Duty 4x4 SuperCab.

I have just bought a 2001 Prius with 127,550 miles. Hybrid battery has been replaced with a used one and all systems seem to work fine except the shift lever in the "Park" position does not lock the transmission. No big problem as long as the Parking Brake works. Preliminary investigation does not reveal any easy fix.

Truck is 04 supercrew with 5.4 and 140,000 miles. I have the typical shutter when cruising 55 - 60 and just ease on the throttle to pass someone. I chalked that up to the torque converter unlocking, if I punch it instead of easing into it, it will not shutter. As of yesterday, it acts like the converter is going to full lock up almost immediately. It will bang when it shifts and rpm's drop to lock up range. A few times it has killed the engine when I shift into D. No codes at all, I removed the programmer and installed the stock tune, no change, unhooked battery, no change, fluid is good, and twice after leaving stop signs it worked perfect until the next stop. I believe that it is an electrical control problem.

How do I fully lock the car after disconnecting the 12V battery negative lead?
It seems to me that the driver's door mechanical lock only works for that one door, not the hatch.

Second time I've had this problem this winter. 2007 Prius, about 65K miles. When the outside temps go below 20 or so the car locks seem to not want to work. For example this morning temp was about 19, smartkey unlocked the car ok-took a couple of button pushes but it worked. Car started fine. Drove to work and after shut down couldn't lock the car. Smartkey didn't work, pushing the door button didn't work. Lock switch inside the car works, so I locked the doors except driver's then used the manual key to lock the driver's door.
I've checked the battery using the internal maintenance screens, no load voltage about 12.3V, Load voltage 11.7Volts, Charging voltage 14.3 volts. I know I'm due for a 12V battery with it being 5 years old and such, and I'm pretty sure a good cold day will kill it dead. But, other than the battery...

Is there any way to make my Prius beep on lock? I know some friends who own Prius and theirs do it, so it is doable. Is there any sequence of buttons you press on the remote that turns it on and off? I bought it used so I suspect that the previous owner turned it off or something.

I am experiencing with my key fobs on my current 2004 Prius. The issue is that I am unable to unlock and lock the car via the SKS Remote, and I am only able to turn on the car via inputting one of the fobs into the slot to turn on the car.
