Finally, installed Omega Rec-43T keyless entry in my 1991 190E 2.3. It is easy to install. Thanks Costanza!

Only one stupid question. Unlock is no problem, but when lock it.... It seems delay. I need to hold the lock buttom few seconds, then the door will lock. Do I need to adjust it? Also, it seems only work within four feets around the car. Do I made mistake during installation?

Anyone has the same problem on it?
