Both keys for my 1997 E220 CONVERTIBLE WONT OPEN THE DOORS. New batteries have been inserted, but nothing.I locked the car this morning with the key which contains the alarm mechanism, but when I went to open later, I couldn''t.I have unlocked the car with the key manually, but dont know if I can open the doors and start it - will the alarm go off ?
