Have him put in 3.5 qts, then check level. 3.9 seems to be too much.

As part of my job, I am incharge of Lost and Found, you would be surprised how many items are turned in and go unclaimed. Unfortunately, I can't return a lot of these items because I don't know who the owners are. I think FOB's are worth putting a small sticker on with your first name and cell # on them. You never know if you are going to loose them and whoever finds it just might give you a call. You definatley don't want your full name, address or home number on it for security reasons.

With a background in electronics, computers, and auto repair, I just had to get a true Toyota Scan Tool with "Factory" software. Cost me about as much as a good used car! Did I mention I also have a NGS Star Scan Tool for my Ford F-150 which does a great job.

My personal opinion is this. For Ford products, you will get a lot of use out of their factory scanner. Most non-dealer shops agree that they see more Ford 'engine lights' than any other make. My F-150 engine light stays on all the time because I refuse to clean the lines to and from the EGR frequently-not a fun job. The plugged lines has no effect on anything that I can tell. Therefore, I just read the computer often to make sure no new codes come in and hardly ever get any new codes except a misfire during seasonal changes-no big deal-just clear the code and go on.

MY person opinion on Prius. The technical services manuals are not well written and difficult at best to understand. This is also true with the scan tool and related manuals. For the most part, you must figure out everything yourself. Good useful Toyota information is available online for an expensive price. Tech Support. ( Dealers have it, of course! ) Therefore I don't recommend anyone getting a scan tool at all for the Prius. My 2005 has 14 computers and the scan tool can access all 14 but little or no useful related technical material is not good. I recently purchased a SmartKey and programmed it for my Prius. The key works the ignition but will not program the doorlocks. I can start and drive the car but cant lock or unlock it! Go figure. I have plently of time to play, so I will figure it out one day.

One last note. Not all scanners are alike. There are Toyota Brand Scanners with firmware thay blocks some programming functions. Wow.
The real test is try the scanner before buying it or get it from someone who knows Toyotas and scanners. I am not sure what I have, but I paid almost $4K so I believe I have all the features, but not sure since I can't program the doorlocks.

RE: The new fob will NOT lock or unlock the doors

Have your dealer scan your prius for any/all errors codes.
You will find one code for the immobilizer.
DTC=1 B2795 unmatched key code.
The dealer has not programmed the FOB correctly.

Dan.... You are the man! I've been searching the net for a long time to find this information. Thanks for sharing your knowldge.


[quote="DanMan32"]They should go to page 05-2266. Apparently for non-SKS fobs, one could do the registration themselves. Pretty complex.

1. driver door open, no key in slot, door unlocked.
2. put valid key in and out of slot twice within 5 seconds.
3. close and open driver door twice.
4. insert and remove key in slot.
5. close and open driver door twice.
6 insert master key in slot and close door.
7. press power on then press power off in one second interval. This is add mode
8. remove key from slot
9. car should lock and unlock door once for add mode.
10. press both buttons on transmitter.
11 within 3 seconds, press one button.
12. car should respond with one lock-unlock. two means it didn't work.
13. open a door or put key in slot.

isnt it a myth that you have to replace the entire ECU when you lose
all the keys? i thought toyota issued a service bulletin on how to
reprogram the ECU with new key entries making a physical replacement
not needed

Well folks, this is NOT a myth, it works great

Finally! How to program a non-SKS key/fob. Detailed!
Ok folks THIS is really how you do this, and yes it really does work. I bought three old keys on ebay anywhere from $23.52 to $50 even. Make sure you have on your original key and have looked on the back for a black toyota logo. This WILL NOT work for the smart keys with the SILVER toyota logo. To get started go to ebay and find an auction for a black logo key. Bid and win and when it gets there, follow these instructions carefully.

The Fob (for operating the car)
This isn't hard, as long as your new fob is not broken and you are able to follow simple directions. The whole process will take less than two minutes.

1. Insert old fob into slot and remove it 4 times in a row, and insert it a fifth time but leave it in there!
2. Open and close driver door 6 times.
3. Remove old fob from slot. Car is in fob programming mode at this point.
4. Insert new fob and leave in the slot for a full minute. Watch the blinking red anti-theft light on the dashboard. When it stops flashing and goes dark, your new fob is all set.
5. Remove the new fob and you're done. You should test both fobs to be sure they work properly.


Now for the door lock functions.


The Fob (for remotely unlocking/locking the doors)
1. Open the driver door with no fob in slot and the driver door unlocked and opened. Other doors can be locked or unlocked, it doesn't matter.
2. Insert old fob into slot and remove it twice within 5 seconds.
3. Close and open driver door twice.
4. Insert and remove old fob once.
5. Close and open driver door twice again.
6. Insert old fob in slot and close door.
7. Without pressing the brake, press power button, wait a second, press it again, wait a second, press it a third time to turn car back off.
8. Remove old fob from slot. You'll be in "add mode" at this point.
9. Car should lock and unlock doors TWICE to verify it is in add mode.
10. Press both buttons on new fob simultaneously for a second and a half!.
11 Within 3 seconds, press only the lock symbol button. yes it does matter which!
12. Car should respond with one quick lock/unlock to verify that the new fob is all set. If the car responds with two lock/unlocks, that means it didn't work. I don't know how to troubleshoot that problem. Maybe just try again.
13. To end this programming, open a door or put fob in the slot.
14. Enjoy the savings from NOT buying a fob from the dealership!!!!!
15. If you want metal keys, DO not buy them from ebay, they quoted me $7.92 CUT by them from dealer.

its a myth

if you lose ALL YOUR KEYS, tow the vehicle to your local toyota dealer, or a friend with the scan tool (preferred, heh)
you will need your license and a copy of the registration (so they say, heh) and they obtain the six digit password
from the vin number, enter it into the scantool, and the scantool erases all the master keys, and allows the
dealer to enter in new keys.

make sure they connect the 12v battery to a charger/tender during the reflashing sequence.

I see the repair for BLACK Smart key below--
But what about my SILVER Smart key--I have only one and want another--what will work to re-program??

See below. Can we mix Black & Silver Fobs, or must they match--I have one Silver and need another fob...cheaper if Black...2005 model

Can I reprogram TWO fobs that start the car, but won't lock or unlock it? They stopped working, I replaced the fob batteries, then took it to my mechanic, who replaced the 12V battery, and now they are telling me I have to take it to the dealer to get the fobs programmed. Would really rather not.
