    First hi to all in the forum, form a just registered prius '07 user from Italy.

    I have several questions, but just start with this one:

    in which of the 2 modes the electronic key/fob's battery is going to last more?

    a) press button on fob to open/close car or
    b) let the automatic system do this (put hand on sensor - press gum-button on car to close) ?

    The fob battery will last for years and is a common, inexpensive battery. So don't worry about which way will make the battery last longer, and just go with whichever way you prefer.

    wow! thanks for quick replying. (my 1st reply)

    So i have another question:
    assume i go for a long trip and want to bring both fobs with me (just in case i lose one), how to leave the second in car while e.g. i am by a client and don't have already a hotel or accomodation?
    If i do everybody could open the car.
    Perhaps removing the battery? Or disabling the smart key system? Or putting some metallic foil around the fob?

    You can lock a second smartkey fob in the car by pressing the "Lock" button on the fob you take with you. When you return to the car, you must use the "Unlock" button on the fob you have with you to unlock the car. No one, including yourself, will be able to walk up to the car and unlock it with the door handle. However, if they were to break into the car, then they could start it and drive off.

    You could take the battery out. Others have suggested putting it in a metal Altoids box (assuming you have such in Italy), but I haven't tried that.

    An Altoids box (or something similar) would work and it could be stored in the hidden compartment. Of course, if you lose the fob you're carrying, you'd still have to get to that second fob (which is now locked inside the car). I suppose one method would be to remove the key from the second fob and hide it somewhere on the *outside* of the car.

    Why cannot you take both keys when you go outside? It's a small thing, keep both in your purse/pockets. :) When I go on trips with friends (anywhere out of town), I always take both keys and give the extra key to a friend to keep in his pocket.

    I think you have the best solution there, Michgal, but provided you're with a friend or friends. From what I could glean from RRB's post, it appears as if he (she?) travels alone, presumably on business trips. In that event, carrying *both* fobs yourself might be unwise. Also, I can understand being hesitant to ask a client to hold a spare fob. ;)

    If i understand correctly, if I lock the car with the lock button, i cannot unlock it with sks using the OTHER fob. But i can unlock with sks using the SAME fob from which i locked ?

    I looked better, taking away the battery is a rather difficult task, i see 4 little philips screws... then one have to take them apart with the cover in some little box or bag and be sure not to lose any component.... :-/

    Finally no idea what an altoid box is, i think a metallic sealed box should do...

    <div class='quotetop'>QUOTE(Michgal007 @ Jun 6 2007, 08:56 PM) [snapback]456708[/snapback]</div>
    ok, i thought about it, but:
    1) sometimes i am alone on trip
    2) i take 1 fob in my pants pocket and 1 could i take in a purse, but if i wish to leave it in the car, (obviously hidden) for some minutes, it does not solve, it still remains active in range for sks.




    p.s. i'm male, name Robert.

    Hello Robert,

    1) How to say this politely? On this area, you are unfortunately (or fortunately) mistaken. But not about you name or gender, I hope. ;)

    Look at the FOB like any other Remote key set. (But MUCH more expensive and complex.) You can lock with FOB1, then unlock with FOB2, then even start with FOB3.


    <div class='quotetop'>QUOTE(RRB @ Jun 6 2007, 05:32 PM) [snapback]456848[/snapback]</div>
    2) Removing the battery is not TOO difficult, if you don't have a short temper. like I have. B) There is a good step-by-step procedure in the Owner's Manual. You just remove the battery, and can then store the battery in a small envelope in your glove box.

    If you lose your primary FOB, once you get into your car, you can still start and drive the car even if the back-up FOB is missing its battery. -- Neat. :rolleyes:


    <div class='quotetop'>QUOTE(RRB @ Jun 6 2007, 05:32 PM) [snapback]456848[/snapback]</div>
    3) Altoids are breath mints (I believe from England). They come in small tins, that way they can charge a lot more for them than "normal" breath mints. B) But yes, any small tin (or even aluminium foil wrap) will do.

    <div class='quotetop'>QUOTE(RRB @ Jun 6 2007, 05:32 PM) [snapback]456848[/snapback]</div>
    4) In this case, you can lock the car using the lock/unlock buttons on the FOB like any remote control. Here, even though the system knows there is a FOB in the cabin, it will still lock the door (because you MUST have another FOB since you ordered the door locked from outside the car).

    I hope this information clears up any confusion.

    An important item concerning Prius' and FOBs: Appareantly if you lose BOTH your FOBs, then it is EXPENSIVE to get you system reprogrammed to completely new FOBs. I'm a Camry Hybrid driver/owner, <_< but I know that has been mentioned MANY times in these forums. A real Prius owner will likely step in an go into this in more depth.

    OK, i got it.

    I've found an old tin box of some pills, "pastiglie bronchiali".
    It works great: if i put the fob in the box and close it don't react at all with the car.

    Good advice, thanks a lot. #1 problem solved!
