One of the doors is not completely closed, or you have a faulty door switch.
The brain for the alarm is under the driver seat just disconect it you should be good!
Insert the ignition key into the ignition and turn it to on, the alarm should shut off.
How do you bypass the alarm on a 2000 Ford ranger cause I replaced the ignition
Insert the correct key into the ignition switch and start the engine. That should shut the alarm off.
Yes you can undo the false alarm after you start the ignition.
Most alarms have an ignition cut off as part of the system, on the steering column the ignition wire should be cut and an alarm wire spliced into it connected to a relay, when you disarm the alarm power is supplied to the relay allowing you to start it. If you intend to keep the alarm off you need to find where they spliced into this wire and reconnect it.
To reset the alarm on a 1999 Town Car, put the key in the ignition and turn the ignition to on then off twice. This should turn the alarm off if you cannot get it to turn off otherwise. If this does not work, then the alarm is probably an aftermarket and the best thing to do is to disconnect the negative battery cable.
try to inspect your your lock and tumbler or key ignition switch.
Unlocking the door and putting the key in the ignition should reset the alarm.
My 1995 Ford Explorer has also done that occasionally ( although I have removed the ignition key as soon as I open the drivers door , the key in ignition chime starts " going " ) What I do is put the ignition key back in and then remove it again and the chime will stop Give that a try
Just unlock the door with the key and open it. The alarm should not go off. If it does insert the key in the ignition and turn it on. The alarm will stop.
Try pulling the master fuse for the ignition to reset the alarm.
