car: MB e320 avantgard. 1996
remote: one button fob.
problem: before change the battery, press the button can unlock and lock the door but the both the red and green light on mirror flash, also the alarm will on when I sit in the car. Then I change the battery of the remote this morning at 11am, it works fine when test before 12am. but at 6pm, the remote stop working, nothing happened when I press the key.
question: I read some threads here, seems like I need re-sync the key, but do not know how to do that (different ways are discussed here, I do not know which one is for me), I do not have manual, so I really need some one tell me how to do this step by step. please.

Welcome to the forum, Urffourm. Please take a moment to complete your user profile, available via the "User CP" link. Your vehicle year and model and your location are especially helpful.
To synchronize the remote on a '96, aim the transmitter at the mirror sensor and press the button twice. Within 30 (?) seconds, put the blade in the ignition lock and turn to position 2. Then turn back to position 0.

1. no problem, profile updated.
2. thank you very much for you kind help, will go to try this way later and let you know the result.
The problem with searching for this information is that our '96's have a completely different system than the later cars, and the synchronization procedure did not remain the same through the years.
Need help about the battery changed remote
