Our X1’s primary remote, which was only a year old, ceased operating. To restart, I have to hold it against the steering wheel.
The old battery only has 2.96 volts, which isn’t the best voltage, but I went ahead and switched it out for a brand-new 2032, and…
There are some hints that I might need to re-sync the key, but I can’t find any information specific to X1.
After changing batteries, it shouldn’t be necessary to resync, especially if the old battery had good voltage.
Get inside the car using a different key to sync. Keep the other key far from the vehicle. Place the key (main remote) against the steering column’s key marks (if no markings then place key against steering column where lock would have been). Keep your key in position when you press the car’s starter. Now that the ignition is turned on, the engine should start if it is on automatic and your foot is on the brake. If this doesn’t work, check to see if the battery is installed properly. If it still doesn’t function, the dealer should probably replace it free of charge (while it’s still under warranty).
You will likely need to reassign driver profile details through idrive if resync is successful.
Every time I unlock the car, one of my fobs displays a low voltage battery error; I’ve replaced the CR2030 cell batteries (3.3v), but the error still appears when using that fob. The second transponder, however, unlocks the car without displaying any errors.
After changing the battery, I encountered the same problem. To fix it, I carefully lifted the two spring metal connections that press against the battery’s underside.
I also verified that there was enough strain between the outer metal connections and the battery edge.
Additionally, it is advised that battery faces be completely clean and free of finger oil, dirt, and other contaminates. I’ve discovered that using fine grit paper to lightly roughen the faces and edge of the battery improves the connection.
It all comes down to the ohmic resistance between the battery face and key fob contacts, and making the battery “snug” will always assist reduce any such resistance.
I’m over this. I believe the cause was some old, stale batteries I had stashed away. purchased some good new Energisers. Varta products are reportedly very good. The problem is that it’s difficult to discern when batteries purchased online are bogus. I’ve even purchased Duracells from Amazon that turned out to be subpar lead acid imitations, ruining my LED flashlight.
