My wife never gets in the driver's seat, nor ever touches either key (after all, she lost the second spare key the first and only time she touched it). Both of my keys were programmed in sequence, and the X5's battery has never gotten low, so there shouldn't be any problem, due to buttons being pushed, nor loss of system power.

I only set the #1 power seat button in memory, once, never the others, but I also never touch any of them, just the manual switches if the positions are incorrect. I guess I'll have to follow the seat & steering memory setting procedure again, and this time set all the buttons thae same.

But what's going on with the mirrors? do they get set in memory too (I've read where they are programmable, but on other BMW models, not the early E53)? Since the remaining 18+ month-old spare key seems to trigger the problem(s), should I

• 1) reprogram it (and the OEM key) to the EWS, then set the seat/steering/mirrors again
• 2) only use the spare key (with a possibly dying battery) in emergencies, or
• 3) buy new spare, uncut keys from my source on ebay, again?
