I would not install remote start until warranty runs out.
I have not been able to lock the door while the proximity key is in its slot whether the car power is on or off. I have not tried taking it out of the slot and doing this. Also, I have only tried this by pressing the electronic door lock button on the door. So I'll try two new variables of 1st leaving the FOB out of it's slot and pressing the door lock button with power on and power off then 2nd with a second FOB and power on and off and let yoou know.
Over all I think you'll be pleased. I bought an '06 with package 6 in August and have a little over 5K miles on it. As an audiofile, I have quite a discerning ear, but the JBL system is most excellent.
I got a little better mileage each tank for the first 5 tanks and it has been steady now somewhere between 44 and 47 mpgs. However I have learned to drive very differently. I was a way too aggressive driver and have turned into more of a grandmother. If you make the fuel consumption screen your default on the LCD display you can't help but be. I'm in central Maryland. You would probably average 50 mpgs in a flatter state. I go light on the pedal and therefore all electric for up to 10 or 12 mph and then accelerate to the speed limit as with any other car. I also learned to let the car go over the speed limit on the downhill if it wants to and there is less labor on the gas motor on the next uphill.
Happy cheap cruising
#357 of 385 Questions about Smart Key
Feb 21, 2007 (11:05 pm)
I was reading the manual for my new Prius, and I'm concerned about draining the battery of the smart key fob, or otherwise messing it up. It says it shouldn't be within 3 ft of electrical appliances like phone chargers and computers. What about cell phones themselves, or pagers? How do you carry both the phone and the key fob on your person and not have interference? It also sounds like the battery will drain faster if the fob is near the car. When I sit at this computer with my key in my pocket, my car is maybe 6 ft away on the other side of a wall, while my CPU is within 2 ft. Do I need to find some other place to store the fob? And while I'm asking, does the fob take standard batteries like AA or AAA or does it need some specialty watch battery? I read how to change the battery but not what kind to use. Thanks, Diane

First, the battery should last much longer than 5 years. Don't worry about it. Just think how many other people are in the same situation as you, and have not reported any problems.
The module in the car calls out to the fob and the fob responds. This happens less than once per second. -IF- other electronic devices could call out, the fob would respond, but the electronic device wouldn't recognize the code, so no action would happen. This is what the warning is about - placing the fob beside something searching for a fob would -slowly- drain the battery. Just remember, this happens when you are in or very close to your car constantly (about once every 5-10 sec., maybe less often). This is how the system operates the immobilizer. If it doesn't get the correct response from the fob and the engine is shut off, you will not be able to start it. So if you placed the fob close to something calling out it would drain the fob battery as fast as it would drain when in the car. Not a big deal.
They may also be worried about large fluctuating magnetic or electric fields, such as the security chip erasers used at checkout counters. There is a slight possibility these could damage the fob, so keep it in your pocket away from the eraser pad.
The battey is a "coin type". Not hard to find. In fact, I've seen them in home centers and food stores. And, of course, Radio Shack.
Finally, even if the battery dies, you just have to plug the fob into the slot in the car and it will work. Of course you would also have to use the key hidden in the fob to get into the car.
The fob is very rugged. I've read of several people who put them through the washing machine (left them in a pocket). After opening and drying them they worked fine.

Aquired a replacement (fob) key from a wrecked 2007 took all the fobs to Toyoto for reprogamming.... did not work.... got still another 2007 fob and took all four keys to toyota to be reprogrammed. did not work. Is there something that is missing here. The dealership said they are waiting on the 2007 scanner.. This is April who is spoofing whom???? Any ideas or hints.

Time to find a dealer who knows what they are doing. There's no change from 2006 to 2007 that I've heard about.

#364 of 385 Electro-magnetic interference with door lock function
Dec 18, 2007 (9:33 am)
I parked my Prius this morning along the waterfront in Point Loma, San Diego, but could not lock my doors in the typical fashion (by pushing the square black button on the door handle). I tried the secondary method of locking the doors with the remote. Nothing working. I had to lock the car with the tertiary method of the door lock switch inside the door. Just then, I turned around and noticed an aircraft carrier returning to port about 1/2 mile away, with it's surface search, air search and navigational radars operating. To confirm my suspicions, I asked a coworker who drives a Prius to come out and try to unlock his car remotely. His keyfob didn't work either, nor did the "touch sensors" on his door handles.
After the ship passed well out of view, we tried our remotes and "touch sensor" methods again, and this time they worked. I think my theory is confirmed that powerful ship radars will interfere with the frequencies used by the remote keyfob. I'm sure there are other sources of electromagnetic energy besides ship radars that could result in the same interference.
Anyone know what exact frequency the keyfobs operate in? Knowing that, we might be able to narrow it down to the exact radar causing the problem.
#365 of 385 How do I open a FOB?
Aug 06, 2008 (10:54 am)
I have a 2006 Prius level 3. The FOB that I have been using for more than two years has been through the wash at least once. Now the button that opens the door locks is stuck in the down position. This prevents me from either locking or unlocking the car using the FOB. I've removed the ring and manual key, slid the top off of the FOB, unscrewed the battery cover, and removed the battery (a Panasonic CR2032 3v by the way), but still I cannot access the button from the back. How can I open the FOB so I can access the buttons from the back?
