    battery in key

    Hi all,
    Changed the battery in the key as I had : low key battery: warning
    on dash.
    New battery didnt work so I changed back to old battery and still doesnt work.This was a new battery after I had changed it earlier last month when I first got low key battery warning.
    Can get into car by using door lock,but alarm goes off and car doesnt start but can turn key to position 2.
    Do I have to program the key again or is it something else.
    beast is 2003 TD6 RR

    You may have to reprogram the key.

    UPDATE:

    Tried reprogramming keys,didnt work, BUT

    Have an old key with the buttons not working anymore(hadnt had battery in it for 3 maybe 4 years)
    Put new battery in it and it cancels alarm and I can start the engine.
    But keyfob still doesnt work on either of them.
    Also suspension wont work(had it in access mode and it raised up to standard height. )

    Will get iid tool on it tomorrow when I have some time and see whats going on.

    Ohh the joys of computers in cars soapbox:

    Hi Laurie,
    Main battery is good, its the only one I got.
    Connected up iid tool and it had a few errors, cleared them all and some came back.
    Mostly the ones that always come on.
    There were a couple of odd ones that didnt have a specific number 0X??
    Took it for a drive as it seems to be behaving itself, suspension lowered to hwy mode on the hwy.
    Went to a locksmith and checked the rfd,s, 1 was working the other not.
    My problem now is that I can only access the car by the doorlock, when I open the door,the alarm sounds until I put key
    in ignition and switch to start position with key, then the alarm goes off. Also only 1 key lets me start the car( the old key with crappy buttons grrr).

    So the question is:
    How do I fix the alarm and how do I get remote locking synced back onto key(s).
    Have tried reprogramming keys and it still doesnt work, the red light doesnt appear after you synch the key, nor does it appear when you press any of the buttons.
    Could it be the bcm is kapput or is it something else.

    All answers greatfully received as to my problem.

    I had to try reprogramming mine several times. I don't recall the exact reason(s) but you have to do both keys. You can't do only one. If you do, only that key will work.

    That's the key to the problem.

    Don't laugh, but did you use a Duracel battery ? Plenty of comments on Ffrr that some other battery brands cause troubles like your having.

    Laurie,
    Definately using Duracell, altho I read somewhere that they used Panasonic batteries when they first came out.

    Key battery does they re-charge?

    I keep getting told that the key fob battery re-charges when you are using the key in the car.
    I'm just wondering how that is possible if there is only one contact (the actual key) going into the vehicle?
    How does that complete any circuit that the battery might be on?
    I'm happy if they do, but I'm thinking that they don't actually re-charge.
    Anybody know for sure?
