The battery is running low on my Mini key (2004 model) its becomming so bad that i have to stand next to the car to open it! I know how to open the key and change the battery. The question is: Will it still work after?
I have heard that you have to take it to the dealer to get the battery changed, because it "flashes" the key and it will no longer work on the car. Is this true? if so, how much will this cost?
I do have a spare key which works, but to be honest, its in perfect condition and i dont wanna use it unless i need to e.g. i lose the other key or something.
In theory the key shouldn't need the battery replacing; they recharge while they are in the ignition, though if you don't drive all that often it could slowly 'bleed' flat. If that is the case, use it manually in the door lock and it will recharge when it is in the ignition. Or you may have a bad battery and it just won't hold a charge. Do note that they don't work seem to work that well in some areas, those with lots of radio waves and other electronic interference. And if you don't use the spare key occasionally, it too will eventually bleed out.
I have an R56 MINI Cooper S race car. I've got the central locking working and the key will unlock / lock both doors but the remote buttons do absolutely nothing.
Yes, this should be the recharging type, and yes that means I shouldn't have to crack it open to change batteries, but as this one looks dead as a Dodo, does anyone know how to open the key? At least that way I can put a multimeter over it to see if the batt is dead or if there's other issues.
Does anyone have URLs for where you can actually get a key battery as mini is dead dead dead. If I can whip the old one out and then whisk the new one in in under 30 seconds then that sounds good to me. Just don't know where to get one from.
