Flat Battery, can’t open vehicle

  • Just returned today from 6 weeks away, and went to start car, but battery is completely flat. Key, and spare, both indicate that they are sending signals, but doors do not unlock. When I look through the window at the dashboard, I see that the clock has stopped.

    Tried the emergency (blade) keys that are hidden within the fob, neither of them do anything.

    Called out breakdown recovery people, they had a quick look but couldn’t get in; they suggest I engage with a locksmith. I’m waiting for a formal call back from their call centre, to confirm this.

    So, any other suggestions out there, or is a locksmith my only option? If I do go down that route, presumably I’m likely to have the lock completely destroyed? Look forward to thoughts.

    Thanks in advance.

    What do you mean by the hidden keys don’t do anything?

    Thanks everyone, I must say that I feel quite flattered that so many of you are taking the time to assist a newbie so quickly.

    Chris — I think my wife got the cordless toothbrush (and other vibrating devices) in the divorce settlement!

    Austy — battery is under the bonnet, in front of the passenger. Thought there might be an easy way of releasing the bonnet without getting into the car, but seemingly not.

    Tony — Thanks for giving me the confidence to push harder clockwise. It didn’t take much, but it does now turn 90 degrees clockwise. Still nothing happens though. Should I be trying for more than 90 degrees? There seems to be no spring in the lock. When the key is inserted at 12 o’clock; it doesn’t matter if I rotate 90 degrees to 3 o’clock or to 9 o’clock, it doesn’t automatically return to 12 o’clock. Is this normal?

  • A correct key ‘will’ turn either way.
    An incorrect key ‘won’t’ turn either way.

    Clockwise will unlock,
    anticlockwise will lock.

    The key will go to about 100 degrees but the inside button will be lifting by about 75 degrees.

    A simialr thing was happening to a member from t’other site. It may be of interest to read this.

    The work around does take some effort and that chap didn’t have the confidence it seems. But it’s the best way to get in if your flat, and the blade fails, imo.

    Thanks M80 and Tony.

    Nothing at all within the first 90 degrees, either way. No movement at all on the inside button, and the lock just feels loose, as if there is no barrel behind it. I’ll persevere for a bit longer but, if no movement by 90 degrees, I am beginning to feel that I’m flogging a dead horse. I’m also a bit wary of breaking the key in the lock, and so compounding the problem.

    Thanks for the link M80, an interesting story. My CLK is a convertible, so I don’t want to go messing around with the rubber seals too much. One thing that the original poster on that thread said that jumped out at me, and it might have just been a throwaway remark, was about breaking a window. Maybe this is the quickest and cheapest option that I have (if the lake of WD40 doesn’t do the trick). It’s got to be cheaper to replace a window, than to replace the locks? (note that I’m badly jet lagged, after travelling around 48 hours to get home, so feel free to tell me to sleep on it if this seems a crazy suggestion!)
