Diamond key

Evening gents, recently bought my first bmw, E46 330ci
Pleased with it so far apart from the annoying bit of having to use the key to lock and unlock.
Read all about the sealed diamond key, just wondered if anyone in Australia (Perth would be handy) knew any info on how or change the battery or a company who can replace it professionally
Cheers

Cheers for the reply mate.
I tried it myself using that video, accidentally snapped one of the terminals off while trying to get the old battery out.
I tried to solder it back on but no luck. Afraid to persist with it incase I damage it to the point of no return

Bummer. Maybe contact a electronics boffin to fix it? He won't charge anything like what BMW AU want for a new fob ($650 odd).

Definitely what he said. I read somewhere that if you push the key buttons more than 60? times the rolling code business loses track and the key needs to be re-initialised.

Spare diamond keys can be had from Bimmernav for about $250. I recommend that you have a spare.

Very good!
Also if you hook the car up to a battery tender and leave the key in position 1 overnight that will charge it and by a slim chance keep you out of trouble for a short while (if the battery is actually not able to hold very much charge anymore)

mate, i have a few spare genuine (used) keys,which you can swap your blade into or swap internal out to your blade. They have not been cut open, you u will need to do that.

of course u will need to repair with your GM

pm if you want one.

oe if much better than thailand ones. few things on the differences which the locksmith wont tell you

1. Thailand clone, does not charge battery
2. The few thai ones ive tried, range was a little less than oe
3. The delay was also more than oe when opening door/boot

Yeah I'd possibly be interested, what do you mean by repair with your GM?
