    Please Help BMW E91 Problems

    BMW E91 (facelift)
    When starting the car, the hatched key symbol on the dashboard. The key did not hold to key slot. I continued drive to home, then i turn off car and go home, after 10 min i come back to my car and cant open car with remote. Then I unlocked with the key manually.
    When I put the key to key reader (slot) dashboard no lights, no warnings, nothing happens..i cant start my car.
    Feeling that the key does not lock to key reader (slot).
    with remote cant lock/unlock doors.

    Worked:
    ~interior lighting
    ~Radio (when turn on manually)

    I checked:~Fuses
    ~battery (car) 12.2V
    ~Battery (key) 3.07V
    ~key reader slot checked, but I did not see anything suspicious.

    Remote key:
    ~did not fall to the ground
    ~no water


    Please help

    Welcome to the Forum!

    Do you have a second key FOB? I am thinking that the FOB is out of sync, and needs to be resynced, but it could be that it's not communicating with the car either, aka a dead FOB.

    No other FOB.
    But whether a damaged FOB explains that it does not hold in slot? The key does not lock after insertion..

    If I remember correctly, if the car doesn't recognize the FOB, it won't lock in. Give this video a try: https://www.youtube.com/watch?v=6qgA06vZizg

    I would also see about getting a second FOB and key.

    "If I remember correctly, if the car doesn't recognize the FOB, it won't lock in." Exactly!
    Reprogrammed car computer and programmed new keys. Now the car was running.
    That was my solution, maybe someone will help.
