93 nissan maxima...keypad locks are on the outside ( i don't know the combo). When I locked the car and shut the door, the alarm started going off, the door key wouldn't work (to get me in the car) and I had to have a wrecker haul it back home. What happened and what do I do to fix it?

If you don"t have the remote and alarm is going off , there are a few ways to get the alarm off . First make sure all doors are closed and hood and trunk as well go to the drivers door and use your key to lock and unlock the car the alarm should disarm if it does not work do the same on passenger door or trunk one should disarm it . All the locks have magnetic switches on them , they do break so if it doesn't work on one lock it should work on one of the others unless all are broke . Hope this helps you .

Im buying a 1999 nissan maxima it did not come with a keyless entry lock remote i never had this kind of a car so i did not know it needed one i noticed the alarm was beeping before i started it but stopped after i guess i did not check the car over good enough before getting it it takes a few times trying to start it before it starts and noticed the key i have to start it does not lock the doors can i by pass the alarm.?

The reason your alarm system is going off is because you used a coat hanger to open the door. This only proves that the system WORKS! It simply thinks that you are trying to steal the car - so it is screaming about it to tell on you!

To get the alarm to turn off, close and lock all of the doors (don't forget the keys :) ) Then use the KEY to open the driver's door. This should disarm the system and the security light will stop flashing and the horn and headlams should turn off and everything should be back to normal.

will your key work in the passengers side?
If so I asume you have electric door locks. open drivers door from inside shut the passengers door. go around to the drivers side shut the door lock the doors from inside then unlock the doors open door shut door and try to start it...as far as disableing it you will have to take it to nissan electrical tec.

this happened to my wife tonight with her 89' maxima but the alarm went off while she had the car in gear and opened the passenger side door to shut it all the way she got the alarm off but the car would not crank..... lights, radio, everything was working just would not turn over I took the keys out locked the driverside door and put in the key and it resets the alarm and car started right up:)

hope this helps,

go to your pass side door and with the battery connected and lock and unlock the car with the key till the alarm turns off from the pass side

now you know what sets off the nissan alarm.lock the car,with the key, hold key over for 30secs then unlock with remote.should reset system....you unlocked the car manually so you need to lock the car manually....

replace the remote's battay

Im no professional but i did recently buy a 93 maxima and i have the same security alarm problem and my powered locks dont work at all. im taking off the door panel today to take a look and see if the alarm sensor is loose or damaged, if it is, ill probably just disconnect it. one thing i have noticed though is that when i hit the lock or unlock button, i hear a faint click from the dashboard area which im assuming is the solenoid on a transistor which would mean that the buttons work but the transistor isnt delivering power. Semi-Solution for Locks: Listen for very quiet click when you lock/unlock doors, if you hear it, uve got major work to do, if you dont, then take apart the door and check the switch connections. Semi-Solution for Alarm: take off the door panel and disconnect the sensor.

If you use the drivers outside door lock to unlock the vehicle it should disarm the vehicle. emmissionwiz is correct, you can't simply shut the factory alarm off.
