    Have a 2002 Zafira that needs its battery changing. How can the battery be replaced with a new one without setting off the car alarm and if possible without having to re-enter the electronics (radio/cd etc.) security code after the battery change?

    Sorry, if this is a very basic question - I have never performed a battery replacement.

    Thanks.

    If it's like my Astra then switch the ignition on (without starting the engine), then switch it off and withdraw the key. Yo now have 15 seconds to disconnect the battery!

    As for deactivating the radio code, again for mine it's:
    Ignition on
    press and hold AS button
    Switch on and hold until bleep
    When prompted enter code with station buttons
    Press AS until bleep
    Radio code is now deactivated.

    As Delbert says. It's the same throughout the Vauxhall range.

    It's best to slacken the battery terminals first so that you aren't rushing to do it while those 15 seconds are ticking away.

    or you could get another battery and a pair of jump leads. loosen the terminals then attach the leads and other battery. then swap battery's and re-connect terminals. take off jump leads and tighten terminals. uninterupted supply.

    Connecting two batteries in parallel is highly dodgy, I'd have thought. If one is even only slightly higher voltage, then a high surge current will doubtless flow in an attempt equalise the voltage. Possibly damaging one or both batteries.

    i have done it this way before, it works fine, it also saves the hassle of having to re-enter your radio code, radio stations and resetting the clock, as there is a permanent live.

    Hi you can also get a code retainer which is a cig lighter to cig lighter lead /small battery which gives enough power to save the code on the radio but you need the ignition in number 2 for it to work which isn't bad and saves alot of hassle
    regards

    I'm not saying it doesn't work. I'm just saying it's bad practice and contrary to the batteries wellbeing.

    The former I can understand, but unless the stereo isn't the factory fit one, the clock will auto update itself from the RDS signal of the stereo.
