Anyone know how to program the e55 smart key? I cant unlock or lock doors just manually with the key, kinda annoying.

Have you changed the battery?

No idea i just got the car from a dealer on Saturday, my guess would be maybe? Since it sat at a warehouse for a while?.

Are they installed correctly? Does the red led on the remote flash when pressing a button? Try aiming the remote right at the black square on the drivers door handle. Aim the remote at your camera on your phone and press a button and you should see a flash coming from the tip of the remote.

I dont see any red light but i do see a flash like light coming out of it when i point i to my camera .

Check fuse 8 in the rear fuse box, if its blown you are looking at either RF amp is dead or what i found is the alarm siren which is on the same fuse has probably filled with rubbish and is shorting out... Alarm siren is located behind the front wheel liner.

Fuse 8 looks good , so im guessing it is gonna be one of the other 2 you mention.

If fuse8 is okay then its either the key, the RF amp or the antenna maybe.
