Electronic key not recognised. Hi, Went out to my Brera just now and found it with both windows fully down. I have seen this before when I accidentally hit some combination on the key fob, so I tried to use the key in the ignition to allow me to put the windows back up.
The battery is really easy to change, but it's not intuitive how to get the fob apart. From memory, first you separate the two halves of the fob, then you rotate the central part that has the metal emergency key inside to reveal the battery. Maybe this picture will help?

#1 · Apr 30, 2017 Hi all, Needs some help here This morning i tried to unlock my 159 with my remote key, but nothing. I replaced battery - nothing. Tried 2nd Key - nothing. I can unlock manually and have checked the relevant fuse on the panel - (to the lower right of the steering wheel).

I have fix almost all the problems with the car, except the keyless remote. I turned off the alarm and remote about 2 years ago with the little key. The car sat for 9 months without a battery in it after the valves and pistons hit. I turned the alarm on in the trunk and nothing seems to work.

Today, when I tried to start my Q4 (July 2017 build, MY2018) the engine would not crank and the IP displayed "Key Fob Not Detected". I placed the fob inside the center console, on the bottom, as instructed by the Owner-User Manual. The engine now started normally, with no IP warning.
