Hi everyone. From couple weeks my E320 having hard time locking and unlocking from the remote control. I changed batteries couple times but no success. Before i was opened with the key and the alarm was starting but now when i open the car there is no alarm. From last week i can not lock it anymore with the remote. Its lock as usual when i start to drive and i can lock it and unlock it from the knob on the dashboard but i can not lock it with the remote and the alarm is gone.
I checked the pump is ok.

IS ANYBODY HAVE ANY SOLUTION???

Thanks in advance!:confused:

It might be that your key has gone bad. I don't suppose you have a spare one to try? I have no idea why your alarm stopped working, but it doesn't seem related.

Are the batteries good ?????

To test the actual key hold it in front of a digital camera, if no beam the either battery contacts or past its sell by date

Malcolm made a good point. Also, are you sure you are inserting the batteries with the proper polarity? I think both positives (+ symbol) must face up.

yes i'm inserting the batteries with the 2 + as is shown on the key.

No i have only one key.

I have doubts about the key, but the alarm and central locking failed. I don't see any interaction between all. Unless is a fuse, but i did checked them.

Still in the middle of nowhere!!!
