Key Repair

Have a 2007 X3si. Warranty expired an 7/28 and I just noticed the my 2nd key is bad. Dealer says the battery cannot be replaced because it is a sealed key and I would have to buy a new one. Anyone have success replacing the battery in their key?

Have not run into this so far with our 07. However, you would think that everything about the key that was important (chip and physical laser-cut key) could be moved to a new shell/battery making the cost pretty much insignificant. However, not sure that would be the BMW way.

Jackson, look back a page to "Remote Unlock Problem" thread - there is a YouTube link I posted on that. Might be a pain but can be done.

There was a thread here a few years back on replacing the battery in the X3 key. It involved a radio shack battery a bit of soldering and you were good to go. The cost was something like $2.00 as I recall. The OP indicated the hardest thing was opening the key case. Someone else might remember the thread or you could try to search for it. Good luck!

My memory of the DIY .....

as the case can only be opened by cutting into it,
as opposed to finding a naturally occurring plastic seam that can be pried apart,
I imagine the caveats are that you might slice into the inside components by accident,
and even if it works, after gluing it back together it will never look or feel quite right.

Worth a try though.

I was at the BMW dealer a few weekends ago buying some parts and discussed the issues that I'm having with my key. I have two keys, one which I never use. I've noticed with my main key, that is has been acting non-responsive. I'll double click to open all doors, but all doors wont open. I'll have to lock, then double click again. Annoying. I was told by the Dealer that the sealed keys are "the worst BMW design ever" and that I would not be able to replace the battery once it died. In fact, I would have to buy a new key (est. $180). I am now using the other key and it's working great. He told me to switch out my keys often, as the battery gets charged in the ignition.

Thanks HilaryEP. They key that died was my spare. It's good to know that the battery is charged when in the ignition. I'll have to start rotating the keys out on the wife's car.

The dealer quoted me the same price for a new key. Works fine for a spare. Just can't push the buttons so I can deal with it.

Thanks again for the info.

I own the Gambit key programmer that has a CHARGE BATTERY function. It is a USB driven device that works on Windows XP. You can purchase and try it.

Our second key was dead 1 day after purchase. The dealer tech charged and reprogrammed it in the ignition. It only took 2 minutes.

Is there any chance you could offer the part or model number for your Gambit charger, X5 guy? Thanks for your thoughts!

If the battery is already dead, you aren't really risking anything other then the price of the battery you are putting in it.

My last post.... Again, if intended to be serviceable, would be serviceable.... Its not about screwing the end user or the risk (other than cutting yourself). Overall, with all the time u wasted with installation time, battery purchase, research, etc... and hopefully it's the battery..... you are further ahead by just buying the key from the dealer.... If you have lots of time on your hands or have something to prove to yourself go for it! If you think its a dead battery, charge it with the vehicle or $100 gambit, or buy a key for $175... Don't forget to program your door locks and trunk to the new key, you can do that yourself without scantool, but need all keys present.

Just remember its just a key..... On to the next repair....
