    Anyone clue`d up on Ak90+ new version ?

    I have bought a key off fleebay and ak90 as i needed a spare key just incase!!! Only to find the key is already coded to another vehicle :( ..
    I`m new to using the Ak90 so still working it out and brain hurts today lol.

    So please explain as if talking to a complete idiot as have only had the AK90 for 24hours and its already been a pain in the butt to install due to driver issues

    Thanks !!

    p.s Any info on changing chip might be useful too if i can`t recode key or MCU Cheers

    You won't be able to reuse the key as it is, but you can disable the onboard chip and fit an older style transponder in the case.

    You need to remove the Elmos SOIC chip and then jump the pins between 3 and 8 which completes the circuit and allows the battery to still change.
    The transponder chip you need will be a BMW prepared (ID44) PCF7935
