    Hi all

    Starting to have a little problem and thought I would post here and see what others think.

    I've always been able to open my 659CC Copen's trunk by holding down the 'unlock' button on the remote.

    Lately (about 10 days) this has started to become a problem. It mostly will unlock the doors ok, though occasionally I need to use the actual key. But more often than not, I now need to open the centre console and press the trunk unlock button as the keyfob won't unlock the trunk.

    I'm not sure if the problem is a dodgy unlock button on the remote (maybe the long press doesn't maintain contact inside the remote well enough to send the long signal to the trunk?) or if there's something going amiss in the trunk receiver.

    I haven't yet tried the only fix I can think of: replacing the battery in the remote, which I haven't yet done in the two years I've owned the car.

    Anyone think that this will fix it, or have suggestions as to what else might be going wrong? The other scary thing is that if the remote dies while the car is locked, unlocking with the key doesn't appear to disengage the engine immobiliser.

    Thoughts?

    My boot has never opened with the remote :cry: but I would try a new battery in the remote first. My remote started not working intermittently and it was just the battery. I changed it when I got stranded in a car park with the alarm going off because I opened the door with the key :banghead:

    Yep, likely to be the battery, not enough juice for a prolonged key press.

    Agreed - battery
    Same symptoms
    Weirdly the battery tag was soldered or welded on, it will come away with some persuasion, then a standard replacement works fine

    Sure enough, replaced the battery and all is good again, should have done it ages ago, cost me AUD$2.95, bargain!

    Haha - I did exactly the same thing, I was locking it manually (actually, not bothering at all) for several weeks, expecting the worst - that the fob was broken. I even looked at a few replacement key websites
    then 'Sure enough, replaced the battery and all was good again, should have done it ages before, cost me HK$2, bargain!'

    Cos I use my car for work and my gear is in the trunk, three to five stops a day, open close open close, I've actually worried about wearing something out!!

    My car just came with a key and no fob....I presume this is something I can buy/replaceable but how to go about it?

    You can get a replacement at a daihatsu dealer (expensive). I think it is possible to buy a used one off ebay and reprogram it, but I do not exactly know how
