"Unprogramming" a memory key?

Deprograming? Unprogramming? Not sure what to call it, but in all my years I have never run into this.

One of the keys on my 2002 4.6is clearly has a memory function in it for the hobbit that likely owned it before me.

When I turn the key, the steering wheel starts to automatically drop to the lowest position. The seats, nor the mirrors, move at all.

I have tried the simple memory steps (door open, set seat memory) and like I said - seat memory works fine but the steering wheel still drops.

Is there some procedure I'm missing here to have the key "forget" that memory setting? Or a different reset procedure? It's driving me batty.

If the memory is working correctly it should remember the last adjusted settings on that key memory when you lock the doors with that remote.

There is a difference in how key memory works if the key fob is used vs. the key blade.

I used to have the exact problem you describe and would have to hit my M1 memory regularly to undo the mystery key memory.

The solution; get in the car.

Once the troll setting is done adjusting, recall your memory setting.

Now roll down your window.

Reach out and lock and unlock with the key blade.

This fix worked for me any time it ever came up. I never figured out what magic of somebody moving my seat and key use that got the key memory not synced.

Report back please.

I have never seen an issue like this before but low and behold, this worked a treat.

This was particularly problematic for me as the motor in the column likes to get stuck. In fact, one of the reasons the car was selling cheap was the steering wheel was "stuck" in the lowest position but I was fortunately able to get it back up playing around with the mechanism. However, when it goes back down it wants to stick again, so I *REALLY* needed this to go away.

But yeah, bingo! I used the seat memory to interrupt the wheel going down, then rolled the window down, locked and unlocked the car, and it hasn't moved again!

Mine hasn't done the issue in years but I had it happen half a dozen times or more, I suspect related to changing which key I used and sometimes with fob sometimes with blade.

E70 you can stop the wheel dance by overcurrent the motor by pulling down on the wheel while it's trying to park for departure but e53 that trick doesn't work. Also is temporary until you adjust the wheel in any way.

My eyes skipped all your other words and IMMEDIATELY fixated on the M1.

Then I actually read the rest

For a few seconds there you were an M1 car owner

That's awesome.

To fix your X5, first get in your M1 and drive over next to your X5.

Bwahhaahhaa.


Re reading I wrote "hit your M1" so maybe drive into your M1 with your X5? That'd be an expensive cure.

Just an FYI to verify the procedure Andrewwynn laid out…pay special attention to the 2nd & 3rd paragraph in the BMW tech info below on how the PM-SM (power module-seat module) operates in regards to memory:
