Dead battery opened the door using the key as the Nissan ob

This answer was rated:

Dead battery opened the door using the key as the Nissan ob would not unlock the door. Attempted a boost start. The engine started but the car horn keeps beeping. How do I turn off the horn?
JA: Did you test the battery with a voltmeter? And have you ever changed one before?
Customer: I usually have a dead battety as I store the vehicle for 6 months. I think my problem was that I unlocked the door using the key instead of the FOB. I've started a dead 350z battery before but I belive the dood was opened by the FOB and not the key.
JA: What year is your 350Z?
Customer: 07
JA: Are you fixing your 350Z yourself? What have you tried so far?
Customer: I have a lithium battery charge device which started the vehicle OK. Its just the horn which is a nuicance.
JA: Anything else you want the mechanic to know before I connect you?
Customer: No Just hjow to solve the horn isue.
