Dead key - happy ending
 

2011 X5

I never really knew much about the battery in the fob or what it might mean if it died. Three weeks ago, I was left using only the emergency key inside the fob. Putting the fob in the slot for a couple of long trips did nothing. Dead Dead Dead.

All the horror stories about $350 replacements and DYI dremel-assisted dismantling and resoldering sounded like to much cost or trouble so I just let it go.

Yesterday, we took the X5 in for a free 99 point inspection (part of a local dealer celebration) and they found a couple of warranty items. Good for us.

While we were there I happened to ask what a new fob/key might cost because my fob battery died and wouldn't recharge.

The helpful fellow took my key, popped open the secret hatch, :wow: and popped in a new CR-2032 battery and all was right in the world once again. :thumbup:

So, before you break open your key, check and see if the battery is simply accessible and replaceable. I never would have seen the battery compartment cover... and it's not mentioned in the manual. :dunno:

Comfort Access = Replaceable Battery
no comfort access = battery charges via induction in ignition

Did you even google this?

Thank you for pointing out the obvious.
I have less time on my hands than some.

Just for future FYI, page 37 of the manual.;)

Ah well. I own two other BMWs without this feature and the X5 belongs to my darling bride. Who would have imagined BMW would provide a user-serviceable battery exchange? What made them give up their $350 new key cash cow?

Of course this all happened as I was informed that the 2011 has one-use rotors. Replace pads and replace rotors. What planet is this? So why would I imagine they would let me change my own fob battery....

I appreciate the wisdom and experience of this forum.
